Service of power aggregates

SERVICE CONTROL AUGE A4 A4 is carried out for all power units. The intersavice service interval is 15,000 km. It is possible to serve engines, both in the car service, and with your own hands.

Maintenance card looks like this:

TO-1: Oil change, replacement oil filter. It is carried out after the first 1000-1500 km of run. This stage is also called the cycle, since the motor elements are triggered.

TO-2: Second maintenance Percentage of 10,000 km run. So, the engine oil and the filter are changed again, as well as the air filter element. At this stage, the pressure on the engine and the valve adjustment is also measured.

TO-3: At this stage, which is performed 20,000 km after, the standard oil replacement procedure is carried out, replacement fuel filter, as well as the diagnostics of all engine systems.

TO-4: Fourth maintenance is perhaps the simplest one. After 300,000 km of mileage, only oil and oil filter element change.

TO-5: Fifth, for the engine, as a second breath. This time a lot of things change. So, consider which elements will cover the replacement in the fifth maintenance:

• Change of oil.
• Replacing Oil filter.
• Replacing the air filter.
• Replacing the fuel filtering element.
• Change timing belt and roller or chain.
• If necessary, the generator belt.
• Water pump.
• Valve cover gasket.
• Other elements that need to be replaced.
• Adjusting the valves at which the gas distribution mechanism is adjusted.

The subsequent maintenance is carried out according to the 2-5 card, then according to the relevant run.

Output

Audi A4 engines are one of the reliability standards. At the same time, the design of most motors will not name simple. Serve force aggregate It is real, but what concerns troubleshooting, you will need a trip to the car service.

Audi A4 enginesThese are modern, powerful gasoline and diesel power units. In Russia, buyers offer gasoline engines of the TFSI series with a working volume of 1.8, 2.0 and 3 liters. Diesel power units of TDI volume 2 and 3 liters are also available. At the same time, 1.8 TFSI in the basic version has 120 hp, in a more powerful version there are already 170 horsepower. The same story with a 2-liter diesel Audi. A4 outstanding in different versions 150 or 177 hp

TFSI A4 engines The same volume can easily have completely different power. The reason is not in the design of the motor or software electronic block Control, mainly power depends on turbocharging. More precisely from the performance of the turbine, the larger air volume is able to "inflate" the turbine, the high power The engine Audi A4. Often, two turbines are attached to the engine, in this case the motor gives maximum power. The same principle works and in the case of diesel engines Audi A4.

First we will tell about gasoline engines Audi A4 TFSI Working volume 1.8 and 2 literswhich are almost the same in design. The difference is only during the piston, which in 1.8 TFSI is 84.1 mm, and in a 2-liter 92.8 mm. The diameter of the cylinder in both motors is the same 82.5 mm. This is an inline 4-cylinder, 16 valve engine with a cast-iron cylinder block, aluminum cylinder cylinder cylinder camshafts, Timing chain drive, a system for regulating the phase distribution of intake and exhaust valves.

The injection of fuel combined is carried out in the collector, and directly into the combustion chamber. Inline four-cylinder gas engine Audi A4 has a turbocharger with an intercooler. Of the features, you can mark the AUDI Valvelift System (AVS) valve management system. The valve mechanism of the power unit has hydraulic components.

Engine Audi A4 3.0 TFSIThis is already 6 cylinder V-shaped motor. 6 cylinders account for 24 valves. In the dual head of the cylinder block, 4 camshafts are used. A chain is used as a GDM drive, while not one or two, and much more. You can look at this image below.

If the audio A4 engines of 1.8 and 2 liters have a turbine, then V6 installed a mechanical supercharger, it is installed in the cylinder collapse zone, between two parts of the block head. The use of the supercharger avoids the effect of "turboyama", since the air supply is continuous, there is no need for strong cooling air cooling. Plus compact design and durability of a mechanical compressor. Actually, setting more productive compressors, you can increase the power of the Audi A4 engine.

As for diesel engines of Audi A4 working volume of 2 liters, these power units have fuel injection directly into the combustion chamber and turbine. Pretty economical diesel Audi A4 2.0 TDI with injection system COMMON RAIL., has a large torque of 320 nm. But if gasoline motors Audi. A4 have a timing chain drive, then the diesel has a belt.

Head block cylinder diesel engine Audi. A4 2.0 l TDI The Common Rail injection system is made of aluminum and has a design with a transverse gase duct, two intake and two outlet valves per cylinder. Valves are located vertically and are directed down. Two camshafts are located on top and are connected by gear transmission from a cylindrical gear having a built-in gap compensator between gear teeth. The timing of timber is carried out from the crankshaft using a toothed belt and a gear pulley on the camshaft of the exhaust valve. The valve drive is carried out using roller levers with low friction, equipped with hydrocomathers.

In this motor, an interesting timing scheme was applied. The belt synchronizes the rotation of one camshaft from the crankshaft. And the second camshaft is synchronized with the first at the expense of the gear on the camshafts. Further more detailed technical audi characteristics A4 2.0 TDI

Diesel power aggregates Audi A4 are characterized by a large torque with minimal fuel consumption. The 3-liter turbodiesel produces 500 Nm of torque and accelerates the car to hundreds for 5.9 seconds, while spending less than 6 liters of diesel fuel in mixed mode. Of course, the service and especially the repair of this unit is a very costly event, but for such a dynamics you have to pay.

Automobiles Audi Some of the most desirable representatives secondary market. The reasons for this interest are several: high durability of many models, pleasant finish, good equipping 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.

Unexpectedly large expenses can generate both gasoline and diesel engines. Among petrol aggregates 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 failure 2.5 V6 TDI ( latest versions which, for example, BAU has already been almost spilled from 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 characteristic faults You can only notice the refusing ignition coils and pollution 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, wrought steel crankshaft and an aluminum block 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:

Some unpleasant typical defects in old cars with big 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. 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 younger and more powerful versions 1.9 TDI appeared more solutions 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. Drive chain 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 motor oil. There are problems with a turbine, distributive treals and electronics.

Flashing sheep are also among diesel aggregates. 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 quite reliable modern engine It will be roads in content and maintenance.

Audi A4 - a car belonging to the middle class produced by the German automobile enterprise Audi AG. Audi A4, and until 1995 Audi 80. This is a successor model F103. In 2011, a 5-million copy of A4 came up from the plant conveyor. Today, sales are so high that Audi A4 ranks 4th in the number of cars produced in Germany. Four is made with 4 types of body - two- and four-door sedans, a convertible and a 5-door wagon.

EA827 engine with a volume of 1.6l., Was developed in the distant 1985. He represented a block with short-terrestrial crankshaft At 77.4mm and the diameters of the cylinders in 81mm. The engine with one camshaft and eight valves in the GBC (SOHC 8V). Versions of engines with injection technology on an inlet shaft were equipped with a system for changing the phases of gas distribution. Adjustment of valve gaps on this engine not needed, because In the design of the motor are hydrocomathers.

Engines 1.4 TSI EA211 series are equipped with a turbocharging system in a pair with an intercooler, which is installed in the intake manifold. Depending on the modification of the engine, the turbine is installed in various types. The main advantage new Series Before the old are the smallest internal wafing and more economical fuel consumption.

We have a finalized version of the widely known atmospheric 1.8-liter four-cylinder VW engine, the main innovation of which was the use of turbocharging. The GBC in the motor is used by a 20 valve, 5 valves per cylinder, with a gas distribution phase change system on an inlet shaft. There are hydraulic components, so you will not need to adjust the valve to 1.8t. The timing belt is used in the timing drive, which is preferably every ~ 60.000 km, when the belt breaks the motor will fit the valve.

The two-liter engine of the EA113 TFSI series was published in 2004 and was developed on the basis of an atmospheric motor with direct fuel injection VW 2.0 FSI. The main differences between the two engines is not difficult to guess in the first added letter - new Motor Equipped with turbocharged. This is not the only difference, under high power The power unit needs to be competently prepared in TFSI instead of an aluminum cylinder block using a cast-iron with a modified balancing mechanism with two balancing shafts, a different crankshaft with thick thrust tides, modified under a reduced degree of piston compression on enhanced connecting rods, is used.

The 6-speed automatic transmission ZF 6HP19 / A (09L via VAG) is used since the 2000th year for rear and full-drive BMW, front and all-wheel drive Audi (as 6HP19A), Hyundai. Designed for engines with a capacity of up to 3.5 liters. In 2006, electrician box was seriously updated in the next modification of this family - 6HP21. After that, the automatic transmission has a new 2nd generation mechatronics with improved gear shift, the valve plate, solenoids changed, the 7th hydroaccumulator appeared, have some friction and almost all steel discs.

Automatic transmission ZF 6HP26, having 6 high-speed modes, Designed together with BMW specialists. Starting from 2001, she began to embed into all prestigious cars equipped with rear wheel drive and possessing engines up to 6 liters. Modified ZF 6HP26A equipped the front-wheel drive Volkswagen and Audi. The torque indicator can reach a mark of 600 nm. Then there were new modifications of automatic transmission - 6HP19 -21 for engines with a smaller torque (up to 420 nm), ZF 6HP32 for DVS with torque up to 750 nm).

The 5-step automatic transmission ZF 5HP19 was developed in 1995 for anterior and all-wheel drive AUDI and was designed based on 4-speed 4HP18 and 5-speed 5HP18 (with which most nodes are identical). The difference between 5HP19 is that it is designed for a slightly larger torque than 5HP18 and aggregated with engines up to 4 liters.
