Reliable and not very. All about motor and Boxes Audi A4 (B7). Car reliability: Five main myths Modern Audi Motors There are among them good

The German automobile company Audi has been part of the Volkswagen Group concern since 1964. Her main motto is "progress through technology." Machines of this brand perfectly combine the sophistication of the design using all the latest developments in the field of automotive industry. Audi brand cars are also recognized as the best among all the secondary market cars.

Audi has in its asset almost a century of car release, firmly occupying among automakers of the premium segment cars leading place. The story began in 1909 with the opening of the company's production firm. The first car, Audi A, appeared smoothly a year later. Having survived the ups and downs, the company joined the Volkswagen concern.

Having access to new facilities and technological solutions, a triumphal march of Audi luxury developments begins. A large-scale development was the four-wheel drive implemented in the Audi 80 Quattro version and for a long time determining the brand's corporate style.

At the nineties of the last century, the boom of technical developments. A8 serial cars managed to "move" into an aluminum body, and A6 got a variator with a metal strap. The Germans during this period released a huge set of cars, but only their part was able to award the title of very reliable.

Audi A1.

When a subcompact model Audi A1 was presented at the 2010 Geneva Salon of 2010, she instantly became a hit. In the process of creation, it took a lot from their progenitor - three-door Volkswagen Polo V. The restyling took place in 2015 led to a change in the external appearance of the machine, and also expanded the list of power units by making them more economical and productive, compared with previous versions, installations.

For the entire period of its production, the model constantly occupied the top positions in the ratings of reliability of cars not only inside the Audi model range, but also among all world-class automakers.

According to the most reliable small-class machines, the DekRa rating agency has brought Audi A1 to the highest line. According to the collected club ADAC statistics, the thousand cars have only 6 breakdowns. "Weakness" sin wheeled discs, corrosive over time, and the occasional blockage of the front optics of the machine.

The car in the dealer salons of the Russian Federation is officially absent, but it can be available in the European Union without any problems. The acquisition of an excellent quality machine is possible for the amount of 20 thousand euros.

Audi TT.

The release of the compact coupe Audi TT officially started in 1998, the concept car appeared on the public at the Frankfurt Motor Show in three years earlier. The first generation of the car was performed continuously until 2006. It is curious that the first 320 copies of TT were deprived of the reverse transmission, which was a clear challenge to German legislation, allowing you to move back in the low speed on the lane allocated for the technique.

The second generation of Audi Tt Coupe appeared at the Tokyo Motor Show in 2005, demonstrating a lightweight durable body from aluminum and steel alloy.

The third generation has become available to everyone to enjoy the quality of the AUDI since 2015. The machine is easily recognizable, stylish, interesting, modern, with a salon, made on the highest category and high-tech filling, it certainly confirms its status of a premium segment.

Since the release of the car with enviable constancy occupies a leading position in all sorts of ratings devoted to the reliability of AUDI cars. In the annual report of the TUV Report (full rankings of used cars) at the beginning of 2019, the model confidently took the fifth place among the machines of different manufacturers up to five years, and on the third - up to seven years.

In the Russian Federation, the car can be brought in car dealerships only in the body coupe, the model price scale begins from 2.7 million rubles. In Germany, the car is presented in six variations - Coupe, RS Coupe, TTS Coupe, Roadster, RS Roadster, TTS Roadster. Naturally, to overtake from the countries of Europe. The used version of the machine with mileage can be in any body.

Audi Q3.

Concept-car was developed and demonstrated by Autoward in 2007, but for the first time the serial car "published" on the showroom in Shanghai (2011). Three years later (2014), the car was transformed after a planned restyling, and in 2018 it was time to reveal the second generation of Audi Q3.

The exterior of the car was significantly updated and recycled. The salon has become even more beautiful and more convenient, the quality of the interior decoration has increased significantly. The engines that can be equipped with a machine are presented with a large line of capacity capable of working on both gasoline and diesel.

If you believe the documentation published by TUV Report, the Audi Q3 confidently keeps the fifth place for reliability in the age group of two- and three-year-old cars of different manufacturers and takes 21 positions from a hundred competitors on the reliability of the Iron Friend "under the age of 5 years.

Purchase Audi Q3 is possible only in the European Union. The purchase budget begins from 33.7 thousand euros. In our country, it is only planned to sell this car through a network of dealer centers, however, the cost for Russia is still not defined.

Audi Q7.

The production of the Audi Q7 model line was launched in 2005, after demonstrating the new public on the Frankfurt Motor Show. Being a full-size crossover with a constant full-wheel drive, Q7 has the same platform with Volkswagen Touareg and Porsche Cayenne.

The second generation of the car, available for purchase since 2015, has a new platform and a fundamentally modified appearance outside and from the inside. During the alterations and restyling, the dimensions of the car slightly decreased, but at the expense of other changes, the salon began to look even more spacious. The list of equipment, standard and optional, has become much longer, offering more features.

As an SUV, AUDI Q7 in Russian realities is better not to use - for this there are more sharpened models for an offrophud. The absence of poles and the parquet concept applied to the engine and transmission significantly reduces the car's passability. But its convenience and reliability for the city and the track are above all praise. With crash tests, passengers inside the Audi Q7 due to the strength of the spars remained safely, which could not be said about the passengers of other small cars, which became participants in the "test" accident.

Based on the "Consumer Reports" rating, Audi Q7 took the ninth place, and experts took into account not only the number of repair statistics, but also focused on their subjective sensations from the machine on the high-speed track.

In Russia, Audi Q7 Neshevaya car - the sale begins with 4 million rubles, or, if you buy it in Germany, you will have to give 64 with a small tail of thousands of euros.

AUDI A4 / A5

The first AUDI A4 generation was created on the basis of Volkswagen Passat with a focus on passive safety and enhancing course stability. The release of the car officially began in 1994, the latter cars went off the conveyor only in 2001.

The model over the years has undergone five generations, but today buyers can acquire the fifth generation of sedan. It has a memorable stylish appearance, excellent interior design and high-tech "inside." The car is easily suitable for both family trips and working trips. The most important thing is the quality of the assembly remains excellent, not causing complaints, and the materials for finishing are modern and racks. The level of reliability of the car is also very high.

According to TUV Report, provided regularly, the reliability of the car is confirmed among the machines under the age of 3 years the tenth line of the rating, the number of breakdowns does not exceed 3.3%. Among age cars under 5 years old AUDI A4 is lowered by the 26th line of the ranking, which is associated with 7% breakage. Maximum number of complaints cause two-liter gasoline engines, at which after 100,000 mileage kilometers and the accompanying problems with naigar and production are starting. Absolutely the same indicators of reliability demonstrates the AUDI A5 model, on the fact that is a sports modification version A4.

Model A4 on the territory of Russia minimally starts with a basic configuration from 2.2 million rubles, and sales of the basic coupe A5 begins from 3 million rubles.

Audi A3.

The A3 model was designed as a small family class car. In 1996, with the beginning of production, the car has repeatedly appeared in all sorts of rated ratings that determine the reliability of cars - they took into account data on different world automakers. In January 2019, researchers from TUV Report marked the rating positions of reliability for Audi A3: 17 line among the machines at a five-year period of operation, and 16 - with a seven-year.

The first two generations of the vehicles were made only in the option of the hatchback, the third generation was also available in the modifications of the sedan, cabriolet and sportsback. In Russia, AUDI A3 dealers can be found only in the option of hatchback, the price of which does not fall below 1.9 million rubles, and sedan - from 1.9 million rubles.

Audi A6.

The first Audi A6 model, assembled on the conveyor in 1994, was replaced by the preceding model of Audi 100. Three years later, the second generation of A6 saw the light of the second generation, which became one of the most sought-after models of the Audi line at the expanses of Russia.

There are several reasons:

Body with excellent galvanized;

Salon is spacious and comfortable;
The machine is equipped with a complete type of quattro type;
The unsurpassed reliability of the gasoline engine (diesel turned out to be more capricious).

The fourth version of the model saw the light in 2011, and after another three years, the car held restyling, as a result of which the style and quality became much more interesting, better, and high technologies used in the stuffing made the car more technological.

Audi A6 has a first-class salon, made using premium materials, a spacious trunk and a large power line of engines offering a choice from 180 to 310 hp.

According to TUV Report, among the three-year-old cars Audi A6 ranks 13th, among the five-year-14th - the 14th, and among the age seven-year-olds - the 7th, confirming its reliability, not deteriorating over time.

Conclusion

It is safe to say that all modern cars of the company Audi retain the inherent reliability and high quality inherent in the German auto industry, which is a direct evidence of the growth of the sales of these firms around the world.

Deservedly was considered an extremely successful model and was produced from 1997 to 2004. The design of the chassis was very promising, but even the most successful cars cannot live on the conveyor forever, especially in the premium segment, where the company settled from the end of the 80s.

New A6 in the body that received the designation C6 / 4F inherited many generic features of the last model, including layout and suspension design. But the body has noticeably added in size and, of course, replaced the entire line of motors. No smaller changes occurred inside: MMI multimedia system - only the visible part of Iceberg. Outside the field of view, a more complex structure of electronic blocks and executive devices remained at times. Well, as it should be, more chic, "premiums", dynamics and ... prices. All according to the laws of the genre.

And the car is remembered by the monstrous V10 at S6 and RS6 sports versions. The motor of the same modular series as the V6 and V8 FSI, but it is based on this block that the unit for the new Lamborghini will make it later. And for Audi, the atmospheric option of 5.2 liters with a direct injection with a capacity of 435 liters was supplied. from. And absolutely unreal biturbo amount of 5.0 liters and with a capacity of 580 liters. s., Moreover, with a good stock for additional forcing.

In the process of restyling 2008, the car seriously changed appearance, electronic filling and line of motors. And immediately managed to light up in a scandal with a review of several stages of cars with a motor 3.0 TFSI, which literally "lured" the piston group is not just fast (what the owners are already accustomed to), but very quickly. Fortunately, a pleasant surprise was seized for Russian owners, leaving a three-liter V6 of the old reliable series at 218 liters in the gamma of motors. With., Which, along with Diesel 3.0, looked simply amazingly against the background of extremely problematic more "perfect" motors with their "male", cracks and even fires. However, let's go about everything in more detail.

I also pay attention to the frame of the windshield - there are damage to the LCP, and the state of the suture sealant in the pumping space of the machines with Motors V8 and diesel V6, a large load on the front and high temperature can damage the seams very early, but such a defect occurs infrequently. The beautiful Salon A6 is in itself a lot of potential "crickets". Alas, the complexity of the reinforcement works is much higher than the average, the breakdown of additional equipment is often found, poorly diagnosed and periodically you have to remove the seats, door lifting, and even the dashboard to access blocks and connectors. It is difficult to collect everything, and the materials are aging over time. In general, the design on multiple assembly-disassembly is not calculated. But the quality of the materials has become even better, except that the skin of the seats and the steering wheel is no longer so good, as in old cars, they often occur. But the buttons with white dread zones do not see, all inserts are silver or happy with a wooden gloss, like new, many, many years. And the smallest works are not bad even in age, the buttons do not lose the elasticity and clarity of switching.

Serious breakdowns? The climate block can "please" by the refusal of one of the six engine devices. New roads, and changing the outstanding detail for a long time and chorely, services often offer removal of the dashboard entirely to perform work. The fan motor is not particularly reliable, climate displays over time "burn out" - the loops lose contact, MMI loses the sound, buttons, settings, navigation ... Control keys on the central tunnel in the vulnerability zone - they are often tritely poured with liquid. By the way, sometimes the land of the hatch in the roof and autumn leaves - they score drains, and then water flows into the salon, right in the center.

A broken handbrake button is already our "jokes" - many owners are trying to "fift" or simply pull sharply, "before clicking". It is clear that the Germans did not count on such barbarism, the key simply breaks. And the cigarette lighter is unfortunate, coins or metal garbage can enter its vertical connector and cause short circuit.

Otherwise, everything is fine, and the interior status depends on the quality of the service, where A6 was served, as well as from the number of interconnect electronics. Machines are not so old, a complete set of problems is only present on completely sequential copies killed by "high-quality" dealer service with a multiple replacement of elements, and on traveling machines that are operated "on slaughter".

Electrician and electronics

This car needs to be very, very love. And never throw, otherwise then it's just not to restore it. Electronic blocks are more than three dozen, they are all very differently: someone quietly dies, someone puts the entire bus and persistently diagnose, someone gives something much more intense. The system can work for years without failures, but if problems appear, they are solved long and expensive. Of the more banal, purely electrical problems - headlights, proofreaders, reflectors, glass itself, on restyling one more trouble - the LED ruler goes out. If the ESP acceleration sensor fails, the half of the "very necessary functions" stops and the error on the ... is correct, on the ABS unit. In general, without a scanner and knowledge of the features of the car there is nothing to do. And also the pumping spit on motors 4.2 and the sensors live long - they are hot. Starters and fans live a little on all gasoline V6 and V8. Rear parking sensors suffer from weak sensors. I am afraid that the list of those electronic components that regularly spoil the life of the owners will be long. They are too much to allocate really serious patterns. The future owner is simply worth being prepared for everything and relate even to the trifles extremely seriously. And avoid servicing in services, where such a car is seen for the first time.

Suspension, brake system and steering

In front, the bottom front and upper levers are traditionally suffering. Behind also, it is precisely the top levers be in order to be the first. Fortunately, almost all loaded nodes have replaceable silent blocks at least on one side, and the cost of spare parts is low. Separately, it is worth noting that the silent blocks of the front subframe also need to be changed regularly, especially on machines with powerful motors. The wheel bearings from the front run only 100-120 thousand on machines with heavy motors and sports suspension. Behind the resource depends on the mode of operation: if the car often drives full load and in bad roads, you will have to change after hundreds. If this is urban exploitation, and even a maximum of one passenger, then they can be said almost eternal.

Optional pneumatic suspension occurs infrequently, and the fame goes bad about her. But now the price of pneumoballons is no longer pregnant, there are substitutes and craftsmen, repairing systems and even refining them. For example, you can put a sealed casing, A-La Porsche and strengthen the system with a large receiver.

The steering is perfectly traditional here: the hydraulicel and the rail with the servotronic. Everything is quite reliably, the rail is not prone to leaks and stacks, the hydraulics is good, the tubes do not flow, the pump is reliable. Companion on a small resource of steering and tips is mainly characteristic of machines with very wide rubber. The brakes are characterized by sizes and successful design. Large brake discs are prone to warping and even imbalance over time, they should be changed on time. And the resource of the pad is small, but it is typically for heavy and powerful machines. Otherwise, everything is very reliable: the brake pipes are very rarely fed even in the machines of the very first issues, and the ABS unit suffers except from the problems with the onboard electronics. However, when buying a car it is worth paying attention to the "Colthozing" - brakes with Porsche Panamera or another custom set of brake discs and calipers occurs relatively often. It often refuses the handbrake, but also the problems of a pure electric nature - breaks the wiring to individual motors of its drive, and people in addition break the control button in the cabin.

Transmissions

If the owner goes carefully and at the same time changes the oil in the box often, at least once every 40-60 thousand kilometers, it will pass more than 200 thousand, and the scope of restoration work will not be very large: repair GDT, friction replacement and something little things. But usually exploitation is much tougher - frequent gas races in the floor (remember, this is quattro), irregular oil change with an interval of 60-100 thousand kilometers or "to shock", plus constant overheating boxes. It is surprising that the design withstands at least 150-200 thousand kilometers in such conditions. But the price of repair ... Replacement of clutches and linings of the GDT is added to the repair of the boxes - they are broken by dirty oil with vibrations, plus repairs or replacement of mechatronics. The mechatronic block costs 300 thousand rubles, the repair is from 15 thousand, but the typical price of intervention is about 50-70 thousand rubles. The quality of repair is "how lucky." And even the purchase of the competent owner often does not save from expenses - the transition to a regular "partial" oil replacement at each or every second, then the installation of a reinforced radiator with filter with the filter will only prolong the agony. If the oil pressure in the automatic transmission is already reduced, then the wear will go in reinforced pace, and any "acceleration into the floor" to reduce it sharply. And, unfortunately, the boxes during runs from 80-100 thousand begin to capricious: strikes when switching, failures, illogical work. The problem is not always possible to just localize, many cars go to the years. Fortunately, the adaptive capabilities of the management system of the Great and the dealer scanner with the new firmware are creating wonders: often already explicitly dying structures go to the last jerk and stretch another 30-50 thousand km of quite normal operation after adaptations. And the variator, and the ZF 6HP automatic machine is more likely to break the owners with their attitude. It should be understood that the powerful car is bought to use it with power, and not stand in traffic jams. The variator provides a minimal number of failures with a neat operation and a stable resource, and the "automatic" zf slightly more allows the driver, provides better dynamics, it takes hard accelerations better, but it will also not demolish the bullying.

Motors

All engines - with a combination of belt and chains in the drive of the timing, cast-iron sleeves with inexpensive spare parts and minimum problem areas. Of course, turbocharging on 2.0 requires high-quality service, and the immediate injection of the first generation is quite capricious, but there are adapters for more modern TNVDs and nozzles, high-quality firmware. As a result - from gasoline engines these three are rightly considered the best. With a regular replacement of TRM, consumables, ignition modules and maintaining a control system in good condition, the number of problems is minimal, the resource is far from 300 thousand. 2.4 MPI Motors Series (BDW), 2.8 FSI (CCDA / BDX / CCEA), 3.2 FSI (AUK), 4.2 FSI (BVJ), 5.2 FSI (BXA) and 3.0 TFSI (Caja) are essentially different only by the number of cylinders and piston running . They have a unified cylinder diameter of 84.5 mm, and the younger motor is distinguished by a simple distributed injection. The problems of these motors are also common.

Audi cars are among the most desirable representatives of the secondary market. The reasons for this interest are several: high durability of many models, pleasant decoration, good equipment and excellent technical data. But, choosing a used "car with rings", you should be careful.

First, low prices are often a harbinger of twisted run or hidden defects. Secondly, spare parts and repair are often roads. Even if nothing breaks, the maintenance costs will be high. At the same time, with an increase in the class Audi, the cost of ownership increases avalanche-like.

If Audi A3 is not so expensive in content, then Audi A6 may be inbox. It's all about a more complex suspension, electronics and a tightly filled motor compartment.

Suddenly, large expenses can generate both gasoline and diesel engines. Among the gasoline units, the breakthrough occurred in 2007. Then under the hood Audi fell 1.4, 1.8 and 2.0 TFSI. At the same time, numerous troubles fell: the timing of the timing was faced, Zhor oil appeared, pistons were destroyed. V6 spoiled a little earlier when 2.4 FSI came to replace the rapid and durable 2.4.

No less complex history and in diesel branch. An example of this successful 1.9 TDI and a failed 2.5 V6 TDI (the latest versions of which, for example, BAU have already been almost spared against the lack). Then there were unsuccessful 2.0 TDI PD with pump-nozzles and a decent 3.0 TDI V6. Later 2.0 TDI PD changed the improved 2.0 TDI CR with the Common Rail injection system.

Gasoline engines

1.6 8V - Low operating costs

From the 1,6-liter gasoline atmospheric, you should not wait for good dynamics and efficiency. However, Audi A3 from 1.6 8V is the cheapest Audi service. The same who loves a dynamic ride, you should stay away from cars with such an engine.

This motor can be found under the hood of the Audi A3 (1st and 2nd generation) and A4 (B5 and B6). It was also widely used in other VW Group cars. It is decent only the first A3, which weighs a little more than a ton. A4 B6 for 1.6 too heavy. The disadvantages include fuel consumption. 9 liters per 100 km seem incompatiently large for mediocre dynamics.

However, in the era of complex motors is the only unit that guarantees low operating costs. Among the characteristic faults, you can only notice the refusing ignition coils and pollution of the throttle valve. Nothing dear. Replacing the timing belt? Installing gas equipment? It does not happen cheaper, especially if you compare with motors with direct injection and chain drive timing.

The engine uses aluminum housing and head. The crankshaft relies on five bearings, and a multipoint (distributed) injection corresponds to the fuel supply. The camshaft is in the head head.

Advantages:

Simple design;

Cheap repair;

Well tolerate the introduction of HBO;

Low cost car.

Disadvantages:

Bad dynamics (overtaking are hardly given, especially in the case of A4);

Comparatively high fuel consumption.

1.8 Turbo - Powerful and reliable

The 1.8-liter turbocharge motor is still worthy of attention. It is durable and fairly cheap in repair. Appreciates the possibility of tuning.

1.8 T provides decent performance and justified fuel consumption. This is one of the first turbosetics, which was widespread. It can be found not only in Audi, but also in Volkswagen, Skoda and Seat. The engine was used even in industry.

The unit has a cast iron block, forged steel crankshaft and an aluminum head of a block with 20 valves (3 intake and 2 graduation per cylinder). To drive one camshaft, a toothed belt is used, and the second shaft is associated with the first short chain. The KKK turbine without moving blades (unchanged geometry), and the injection of fuel is distributed. The block in the "dry state" weighs about 150 kg.

Soon it turned out that 1.8 Turbo has a very big potential. 240 hp serially removed from it, and in the process of tuning it easily withstands the forcing up to 300 hp Of course, in the case of a tuning unit, you should strengthen the vigilance, as it can already be concerned.

And yet, more often, the turbo engine was used not for sports trips. Under normal conditions, a car with such an engine consumes from 9 to 14 liters per 100 km.

With age, a number of disadvantages were found (timing and thermostat), but their elimination does not require high costs.

Advantages:

Good compromise between productivity and fuel consumption;

Availability and availability of spare parts;

A wide selection in the market.

Disadvantages:

Several unpleasant typical defects in old cars with high mileage (oil consumption and timing fault).

Examples of application:

AUDI A3 I (8L);

Audi TT I (8n);

Audi A4 B5, B6 and B7.

2.4 V6 - only until 2005

Despite the appearance of increasingly strong row turbo parts, Audi's fans still prefer the V6 atmospheric gasoline, especially in earlier versions. Of course, you should not count on low fuel consumption - at least 10 liters per 100 km. In the city will have to be considered even with 20 liters. But the trip will seem enjoyable.

Two generations of 2.4 liters are clearly distinguished. They have the same volume and dimensions, but in 2004 modernization occurred. Before the update, the block was cast-iron, and in the head - 30 valves (5 per cylinder). After, the block became aluminum, the number of valves decreased to 24, immediate injection and timing chain appeared.

Recent innovations and summed up. Because of the direct injection system (FSI), after a few tens of thousands of kilometers on the valves accumulated Nagar. There were problems with the tensioner of the timing chain and a small mesh filter in the lubrication system. Full of noise ignoring often ended with a circuit and serious damage. In 2008, Audi eliminated the Vulnerability of the MRM Drive, but the engine did not stand the pressure of 4-cylinder turbogors.

Advantages:

Good elasticity;

High reliability (only before updating);

Versions with distributed injection easily carry the installation of HBO.

Disadvantages:

Limited sense of the GBO installation in the updated version of FSI;

Expensive malfunctions in the work of the timing (FSI);

Pretty high fuel consumption.

Examples of application:

Audi A4 II (B6);

Audi A6 C5 and C6.

Diesel engines

1.9 TDI - Durable and economical

This is the most recognizable diesel for recent years. Even Elderly Audi with 1.9 TDI costs - robust design and inexpensive repair.

1.9 TDI - the engine of the legend. Released from 1991 and was reigning many times upgraded. He found an application in many other VW Group cars.

The most reliable and cheap in operation and repair is recognized as a 90-strong version with a distribution type TNVD. The engine has a simple design, a constant geometry turbine and a single-mask flywheel.

Yes, small problems sometimes happen. For example, with a valve recycling of exhaust gases, air flow meter and fuel pump. But most of their malfunctions are caused by non-constructive miscalculations or low quality, but a decent age and large runs.

In the younger and more powerful versions of 1.9 TDI, more solutions have appeared that can create problems. We are talking about a turbine with a variable geometry, a two-mask flywheel, pump-nozzle and DPF. However, even these versions against the background of diesel engines appear in a more advantageous light.

The exception is the BXE version of 2006-2008, which fell, for example, under the hood of the Audi A3 second generation. There are many cases of turning inserts after 120-150 thousand km.

Advantages:

Simple design;

Good endurance;

Low fuel consumption.

Disadvantages:

Many coupled instances (the engine was installed until 2009, and since 2004 it gradually displaced 2-liter turbodiesel);

Low labor culture: noise and vibration, especially after starting the cold engine.

Examples of application:

AUDI A3 I (8L) and II (8p);

Audi A4 B6 and B7;

Audi A6 C4 and C5.

2.0 TDI CR - finally everything is fine

2-liter diesel - the main unit for most Audi models. Since 2007, he began to use the Common Rail injection system.

The disadvantages of the 2.0 TDI construction with pumps prompted Volkswagen engineers to its solid modernization. Changing the method of nutrition is the most important novelty. The pistons were updated and the problems with the oil pump drive were eliminated, a new block head and camshafts were installed. As a result, the durability of the engine was significantly improved, but there were shortcomings.

Buying Audi with a motor 2.0 TDI, should check the history of the car. Often, these were cheap and cost-effective versions purchased for commercial or corporate garages. They have huge runs and not always well served.

Typical faults affect the two-masted flywheel and turbocharger. Piezoelectric nozzles refuse here no more than that of competitors. Fortunately, they are amenable to restorative repair. Within the framework of the service promotion, the manufacturer has changed high pressure trigger.

Advantages:

Good performance when the fuel consumption is acceptable;

Good durability (especially in comparison with 2.0 TDI PD);

Great variety of versions.

Disadvantages:

Expensive service (complex design and expensive spare parts);

Significant mileage of many copies, despite the relatively young age.

Examples of application:

Audi A4 III (B8);

Audi A6 III (C6).

3.0 TDI - for demanding

High performance and dynamics are not the only advantages of 3.0 TDI. Therefore, many choose him with pleasure, even despite the fairly large service costs.

The 3-liter turbodiesel was called up to correct the evil reputation of diesel V6 Audi, reinforced 2.5 TDI V6. 3.0 TDI deserved respect not only due to performance, but also durability. The block, cylinder head and crank mechanism were very strong. On each cylinder here is 4 valves and one piezoelectric nozzle.

Problems concern mainly equipment. Most often face the timing drive, the cost of replacing which is very expensive. Until 2011, 4 chains were used, and after two. The drive chain is located on the side of the gearbox. To replace it, you have to remove the engine.

Not disposed of flaps in the intake manifold (there are sets for repair) and DPF. The engine is constantly being finalized, and in later versions of faults are much less common.

Advantages:

High culture of work;

Good performance;

Low fuel consumption;

Not bad service life of many engine parts.

Disadvantages:

Expensive in eliminating timing fault, intake manifold and DPF;

Many specimens on the market have high runs and dubious technical condition.

Examples of application:

AUDI A5 I (8T / 8F);

Audi Q7 I (4L);

AUDI A8 II (D3).

A risky choice!

In the Audi assortment there are engines that are beautiful in theory, but in practice it is brought painful disappointment. In particular, the first generation of 1.4 TFSI should be mentioned with a problem chain drive timing. Currently, a more reliable version with the timing belt is used.

We seduce high-speed motors 1.8 and 2.0 TFSI with code designation "EA888". However, they suffer from extensive consumption of engine oil. There are problems with turbine, camshafts and electronics.

Parsi sheep are also among diesel units. For example, a 1.4 TDI with pump-nozzles was installed in Aud A2. The problem is the appearance of the hollow of the crankshaft, the elimination of which is economically impractical. 2.0 TDI PD is known for a cracking head block and low equipment durability. 2.5 TDI V6 torment numerous blunders with timing, as well as with a lubrication and nutrition system.

Conclusion

Once the purchase of Audi was easier - the engines guaranteed quiet operation. Currently, you need to pay attention to the version. Along with the truly successful motors, those for which designers should be ashamed. At the same time, even a fairly reliable modern engine will be roads in content and maintenance.

Audi cars are a typical sample of a German car industry. For this brand, cars are characterized by reliability, durability, excellent maintainability and mandatory equipment of their models the latest technical achievements.

If you deepen a little in history, it is worth staying on truly folk cars in Russia and Ukraine - Audi 80 and Audi 100.
Audi 80, which refers to middle-class cars, was produced in 1966-1996. And his graduate harm to the higher cell model was produced in the approximately the same time range (1968-1994).
These cars imported to the CIS countries in the nineties already, with a significant mileage (more than 150,000 km) had, more, a huge potential resource and engine, and body. Therefore, the first after importation of the repair of Audi was postponed for several years. This was facilitated by several factors:
a) Starting from 1986, these Audi models began to be issued with a fully galvanized body (initially established corrosion guarantee for eight years was increased to twelve);
b) Cars were completed with reliable gasoline (E, S) and diesel engines (D, TD, TDI). A huge number of imported cars have developed up to 500,000 km before overhaul. Separately taken Audi came to our service station for the first overhaul of the engine with a common mileage equal to seven hundred thousand kilometers. The topping of oil for 10,000 km was 1.5-2 liters (so, in principle, these cars could ride a little more).

But Audi A4 and A6 came to replace the unnecessary Audi 80 and 100. The line of the engines was expanded, five-cylinder engines were rushed into the fly, and separate models began to be equipped with a Tiptronic machine box (with an additional manual speed switching).
In 1996, Audi Universal and Audi A4 Quattro with a full drive appeared.
Although new models have and improved appearance, and modern equipment, their reliability decreased somewhat. If you take a reliability rating for 2002 according to the British magazine "Which?", Then for the Audi A6 model (new car), it amounted to 90%, and for Audi A4 and even below - 87%.
All these problems are associated with the general trend of the maintenance of cars by the main world manufacturers. The use of cheaper components always affects quality.

In recent years, Audi cars returned their own, slightly steps, positions. This is a ridicule, comfortable, modern car. But technical achievements have come so far that the quality auto repair Audi can only provide a technical service station equipped with the latter science and technology. This applies to diesel engines. Only competent experts will be able to customize the work of this main assembly of the car, which will immediately turn it out of a simple means of movement in a "rolling horse".

About Audi cars can be told a lot, but let's stop on the main thing: timely, then good specialists are the key to the trouble-free work of your car..

The reader sent a short, but a very capacious question: "Tell me about Audi A4 B7. What engine and gearbox will deliver less problems?" Let's try to give a detailed answer.

It is a further evolutionary development of technologies applied in the preceding generation (and models of the VAG concern). But it is interesting that the share of this "four" fell out the opportunity to "try" completely different motors and transmissions, which ensures greater freedom of choice. And this is for the buyer "BESika" a big plus.

Let's just say: from the point of view of reliability and cost of content, the best combination is a 102-strong gasoline engine 1.6 with a distributed fuel injection (factory index ALZ) and a 5-speed manual transmission. But let's finite: what's the point, buying a premium brand car, come down by running qualities? Therefore, we consider other options for execution, the benefit for A4 a wide line of gasoline and diesel engines was proposed, as well as several fundamentally different transmission options.

If we talk about gasoline versions, you can remember about another "simple" engine - atmospheric 2.0 alt with distributed injection (130 hp). He does not demonstrate anything special in terms of the dynamics or fuel economy, but it is important that with him A4 no longer "vegetable", and there is no special problems foresee. In general, the motor as a motor, which is also better to prefer in a bundle with a 5-speed MCP.

Do you want something more powerful and faster? Then be prepared for this to pay extra. So, even a relatively simple turbo engine 1.8T (BFB) with a capacity of 163 hp More referred to in the quality of fuel, which, besides, the "appetite" consumes - oil consumption of 0.5 l / 1000 km with active ride is quite normal. It may be more if there is also a turbine to flow into the volgar, which begins to "pass" during runs over 200 thousand km. Nevertheless, it is perhaps the optimal option in terms of the balance of power, reliability and cost of content.

After all, the remaining gasoline engines are even more difficult, "capricious" and more expensive in maintenance and repair. In particular, this refers to version 2.0 TFSI, which, depending on the modification, can develop 170 (BPJ, BYK), 200 (BGB, BPG, BWE, BWT) or 220 (BUL) L.S.

The direct fuel injection and turbocharging indicate that the engine is high-tech, respectively, demanding to the quality of technical fluids and fuels, consumables, and, of course, in need of qualified service maintenance.

The components of the fuel system (TNVD and the nozzles) in the case of repair or replacement will cost Neszayevo. However, the likelihood of their failure on the fresh car is minimal, but the increased oil consumption (0.5 l / 1000 km and even more) is quite possible. On some machines, it is observed almost from the very beginning of operation, on other manifested over time. To reduce the "Mouse", it is necessary to change the oil-challenge caps, in the extreme case (and, as a rule, on motors with a large mileage) - piston rings.

The valve of the exhaust gas recirculation system should include the valve of the exhaust gas recirculation system, fuel nozzles ("treated" cleaning, in particularly launched cases - replacement) and ignition coils, but the latter suffer due to late replacement of the candles. On the early years of release, there were problems with a hindered cold start in low temperatures.

As the top for A4, the engine 3.2 V6 FSI (AUK, BKH), which develops 255 hp Let both of the "frisky", but rather "voracious" (despite the direct fuel injection), expensive in service (the chain drive is not eternal, especially if the hydraulic agent is ahead of schedule), and most importantly - with a "disposable" aluminum unit, whose replacement risk of which from - Damage to the alusyl coating of cylinders during runs over 150 thousand km is quite likely.

Therefore, if you need the maximum thrust and power, it is better to pay attention to the diesel "six" with Common Rail - 2.7 TDI V6 (BSG / BPP - 163/180 hp) and 3.0 TDI V6 (BKN / ASB - 204/233 .from.). The last option in combination with a hydromechanical "machine" and a full drive Many brand fans generally consider the most right choice if a powerful, but relatively economical and reliable car is needed. The main thing is that the previous owner does not save on high-quality and timely service and did not "have slept" the car "left" diesel (patient theme for cars from Russia). The use of poor-quality fuels turns into the failure of the unexpected nozzles, but their work in any case should be checked during computer diagnostics. Also worth paying attention to the drive of air dampers in the intake manifold. However, such machines, as a rule, holly and cherish, are decently serviced and extremely reluctantly parted with them, and then only for considerable money.

Until 2006, a 2.5-liter TDI V6 BDG with direct fuel injection (163 hp) was installed at A4. Unlike the predecessors of the series, the GHR drive was finalized, so that the premature wear of rockers is unlikely. But problems with the TNVD Bosch VP44 remained. Also a relatively weak place is a turbine with a variable geometry. There are problems with a piston resource. However, we already, so we will not repeat about this family of engines (though on the example of AUDI A6 C5).

Well, now let's talk about four-cylinder diesel engines with pump-nozzles 1.9 TDI and 2.0 TDI. According to experts, in this case, preference is better to give 1.9-liter option (BRB / BKE factory designation). Let it develop only 115 hp and 285 nm, but generally turns out to be more reliable and cheaper in repair than a 2.0-liter option.

But this does not mean that the 1.9-liter engine can be taken without looking! So, before buying a thorough diagnosis is required. The fuel system should be fuel: it is quite reliable, but in case of failure, the repair hurts the wallet. You should also make sure that the system of changing the turbocharge geometry system is working, which in time begins to "hang", because of which the engine does not develop all the power or in the emergency mode of operation. And at large runs, it is possible to fail the turbine itself ...

By the way, in the case of the 1.9-liter version of the DPF filter, it may not be, since it was not put on all cars of those years of release. But even the presence of a filter should not be embarrassed if the proposed option arranges in all positions. After all, the filter itself is quite durable, but in case of the impossibility of its regeneration, the issue of physical and software elimination has long been learned to decide.

When choosing version 2.0 TDI (136-170 hp), the focus must be in the spotlight (especially if it is less reliable and more expensive piezoelectric), turbine, and the hexagon of the oil pump drive - if it is blunting its wear , You can handle the motor, leaving it without lubrication.

Given the age of the model (8-12 years), we can say that the mileage of the most recent diesel versions is already exceeding 200 thousand km, so that the problems described above are quite possible. It is not necessary to relax with gasoline turbosologists, especially with direct injection. This does not mean that they need to be avoided. Just buying should be preceded by thorough diagnosis, it is desirable that the confirmed mileage of diesel versions be as small as possible.

Well, a few words about the transmission. The full drive is not to be afraid: it is reliable and practically does not affect the cost of the content, provided that it was not "killed" by the previous owners. The choice in favor of the mechanical transmission should be considered true: there is no problem with it, unlike an expensive Multitronic variator repair, even with its modernization. The classic "automatic" ZF is preferable, but, first, they have completed the most powerful versions, and even in conjunction with Quattro, secondly, this box is also not safe: during runs over 200 thousand km, it may be required to be a bulkhead with the friction replacement, solenoids and possibly hydroblock.

In general, if the cost level is important, the principle is "the simpler, the better" works here to the full. Breeding such simple versions in the line "Four" is. It is also not bad that from a constructive point of view, the B7 generation is the further evolution of the predecessor, so unpleasant surprises from the main components and units are minimized. But even taking into account this, it should be understood that the latest AUDI models are not budgetified by definition or in the purchase or in content.

Pulse prices

As the price analysis shows, the weighted average price tag for A4 2006. Located at $ 8500. At the same time, the prices of copies of the first years of release (2004) are at the mark of $ 6,000, and the most recent "four" with the index B7 (2008 G.V.) are twice as expensive. By the way, leaving on peace, reincarnated in the Seat EXEO, which was released until 2013. True, this is a very rare guest in our market.
