With the launch of a new, slightly improved 3-series, Bayerische Motoren Werke, bringing some confusion in their ranks. For example, in Europe new model 330i will replace the previous 328i, but it will happen purely nominally, since the motor will not change its volume and everything will also be presented 2.0 liters.

I remember, there were few other times when everything was different. Everything was much easier and intuitive. Model 328i meant that under the hood there will be a 2.8 liter motor, and 330i, of course, had a 3.0 liter engine under the hood. And so on, and the like, at par.

According to the logic of things, such a "forge" is not accidental and partly justified. Motor volumes are definitely becoming more modest, but the power ..., the power on the contrary grows, and a very rapid pace. Do not have time to look back, and the new model bypass last year's good couple dozens horse power. Over the decades of continuous progress, the engines considered at the beginning of the 90s are small, 1.6, 1.8 and even 2.0 liter engines now give out the capacity greater than the one developed 2.5, 3.0, and then 4.0 liter units at the end of the 20th century.

So it turns out that if you consider in horsepower under the hood, then some BMW with a "modest" and nothing, or a remarkable engine in 2.0 liters can safely make the peak power of 4.0 liter monster of the outsturned century. About others important parameters As an output to the peak torque from 1.800- 2.000 rpm or economy in normal exploitation, generally silent.

And in order to psychologically buyers, it was more comfortable and not to scare customers with signatures 1.6- 1.8 on the trunk lid, like other leading automakers experiment with the names of their models, do not write horsepower on board, in the same case?!

To understand the depth of the value of the nomenclature engines BMW.We will try to find out which top 5 BMW motors put on cars 3-Series for long years. Including and "M" models.

5 - BMW M42 B18, 1.8 liters, row four-cylinder, 138 liters. from. (E30, E36)

Fifth place, took many famous 1.8 liter bMW aggregate. Quieter, quieter, do not drive horses! We understand that it may not be from Bavaria, but listen to us.

First, where was it used? In the lightweight bodies E30 and E36, often in models 318is. Recognize, this is not the most best BMW According to the dynamics and drive (it was so that it was so that the owners of the BMW are all like this notorious "Drive"), but the 1.8-liter motor still fulfilled its mission. For an acceptable price, you purchased a window-portable car with wide refinement capabilities and the dynamics in stock state of just above 10 seconds. For the end of the 80s, the first half of the 90s it was a truly valuable breakthrough. Bavarians brought feeling sports car in mass. Moreover, to acquire models with this engine could anyone without overpayments.

Why did the Germans have not developed success on and did not offer the model for distributing other continents? The case was that the idea prevailed in South Africa, that cool car Must be compact and easy and carry the largest of the most available engines in its rotor space. It is necessary to say, the nor of the coupe was still the one, not everyone was subject to all the power of this rare nugget.

3 - M47, 2.0 liter, petrol row four-cylinder, 136 liters. from. (E46)

With this engine, BMW has shown that diesel can be cheerful. In essence, the 320D model, driven by a strong 16-valve motor, was faster than 2.0-liter 6-cylinder gasoline model 320i, which possessed 148 hp. Both machines reached 100 km / h in 9.9 seconds, after which the torque was given to know about themselves and 320d easily accounted for its less promundant colleague.

Shortly after launching in production, 3-Series created on the basis of M47 installed a high standard for affordable, reliable and economical sports sedans. Sounds paradoxical? Maybe however, this explains why the 320D models are so successful to this day.

2 - S54, 3.2, row six-cylinder, 338 hp (E46)

Okay, enough to talk about 1.8 liter engines And Diesels, it's time to remove heavy artillery. This 3.2-liter monster standing on E46 M3 is undoubtedly one of the best engines BMW from ever created. In its foundation, M54 DOHC is a row six-cylinder engine, an aluminum block and a solid aluminum head of the cylinder block was used.

It had individual throttle valves for each cylinder, lightweight pistons, larger intake valves, a high-pressure high-pressure valve high-pressure gas distribution system for changing phases of gas distribution, the list of advanced technically solutions is not complete, it can be continued for a long time ...

S54 is not far from BMW racing engines and was the last atmospheric native motor installed on M3. Power was enough to overclock the M3 from 0 to 100km / h in 5.1 seconds, with maximum speed Limited at 250 km / h.

1 - S65, 4.0 liters, 420 hp (E90 / 92/93)

What is the easiest way to develop a V8 engine? Well, in the case of BMW, you need to get rid of two cylinders from the engine S85 V10. Yes, the V8 version installed on the 4th generation M3 is derived from the monstrous, inspired F1, road V10, which was in the production line BMW.

03.04.2017

- Compact car produced by the German automaker BMW AG.. BMW "Tryshka" has always been one of the most sought-after cars among young motorists. The addiction to this machine is quite explained, as it is pleasant in all respects: actual appearance, good equipment, powerful power units, high level Comfort and excellent handling. Adds the popularity of this model and the reasonable price of the car on secondary market. And, here's how things are with the reliability of the used BMW 3 series, and what to pay attention to when choosing a "treshka" with mileage, I will tell you in this article.

Some interesting facts:

The presentation of the first BMW 3 series, which had an E-21 index, took place in June 1975, and marked the beginning of the story of the "Trex" BMW. In 1980, a sports version of the car was presented, which was named " BMW M3." In essence, it is a BMW 3 series in the body "coupe", but a BMW refined by the factory branch and is completed only by the most powerful engine. To date, six generations of this car have already changed, but today it will be about the fifth generation of the model, the world premiere, which was held at the Geneva Motor Show in 2005. Depending on the type of body, the car assign the appropriate index: sedan - E90, Universal - E91, coupe - E92, convertible - E93.. When developing the design of the fifth generation of the treshki, the manufacturer did not solve the cardinal change of style, but limited himself to evolutionary changes, bringing the appearance of a treshka in line with the design of senior models.

After half a year after the debut of the sedan, the BMW 3 series appeared on the market in the universal body, and in September 2006, serial production of the car in the body of the coupe began. Since 2007, at all BMW 3 series began to apply the system " Dainemix", Which demonstrated how pleasure driving can be harmonized with exemplary fuel consumption and toxic emissions. BMW 3 Series is the most-selling company model - in 2008 about 40% of sales fell on the 3rd series. Models of this series periodically fall into the list of the best-selling cars in Europe. In total, 2,147,247 copies were produced over the production period of this model.

Disadvantages and common faults BMW 3 series with mileage

BMW 3 series body corresponds to the image of the brand and are not subject to corrosion. Metal body elements Standingly withstands our reagents, and even in places of chips, after several years of operation, in most cases there are no hints on rust. But the body equipment does not boast of exemplary reliability. So, for example, after 2 years of operation, the front optics begins to curb. Over time, the doors handles begin to twist, this ailment is unpleasant in that when it appears, it is necessary to change not only the handle, but also the door lock. Another trouble that is peculiar to cars in age - the seal between rear glass and lid trunk. In most cases, the owners eliminate the problem independently, putting a gum on glue. For the winter you need to pour a high-quality non-freeze for glassesOtherwise, in a heavy frost, when trying to rinse the headlights, the washers will fail.

Engines

Traditionally, for BMW, "Tryshka" has a large number of available power units, but in our secondary market, there are most often cars with such power units: gasoline - 2.0 (136, 150, 168 hp), 2.5 (215 hp), 2.5 (215 hp) .), 3.0 (254, 268 hp), 3.5 (302 hp). Also, diesel engines are quite common - 2.0 (120, 141, 167, 177 hp), 3.0 (194, 201, 228, 242 hp). BMW power units are always associated with power and reliability, but not everything is so unequivocal with the "treshka" motors. One of the most problem seats Engines are considered increased flow Oils - up to 2 liters per 10000 km of run, and, the more the machine has a mileage, the more often the oil will have to top up ( to liter per 1000 km). When maintaining engines, it is necessary to pour the recommended oil, otherwise the oil-challenged caps are premature.

W. power aggregate volume 2.0 valve lid Made of plastic, because of this, over time, oil starts to leak from under it. Also, this motor does not like overheating, and if you do not follow the engine temperature, then, in most cases, the valve lid loses geometry. Once in 60-80 thousand km have to change the sensor of the eccentric shaft. It is worth noting that during its malfunction, the car will not start. Once at 100,000 km is required replacement throttle valve (Valvetronic) - electromotor is covered with oil. The remaining gasoline motors are more reliable, but still, it is difficult to call them difficult. One of the most common ailments of gasoline engines is considered a small catalyst resource, which, even if the quality fuel is refilled, is unlikely to serve more than 70,000 km.

Quite often, the reason for visiting the service center is fuel nozzles, which in our realities on average, only 80-100 thousand km are kept. The first signal on the presence of problems with nozzles will serve: bad speaker acceleration as well sIZY smoke of exhaust system. Chain GRM On average, it serves 150000 km, if you do not notice that the chain began to stretch, everything can end very sadly ( chain jumps and piston bent valve). Over time, the chain tensioner fastening bolt is weakened with vibrations, as a result from under its seals, oil leaks appear. To the mileage of 100 thousand km, the solenoid control of the couplings of the variable phases of gas distribution is clogged with oil sediments. It immediately affects the dynamics, and it happens that the motor goes into emergency mode Work.

Diesel motors

No better situation and with diesel engines. The most problem is the engine 2.0 (177 hp), which, even with a minor mileage, can disrupt the chain from the camshaft drive. If this trouble happens to the engine, you need to be ready to lay out 800-900 cu. for restoration work ( cost, taking into account the original spare parts). The problem was solved after 2008. Also, the disadvantages of this power unit include piezoelectric fuel injectors ( medium resource 50-70 thousand km) that are not subject to recovery.

Two-liter motor with a capacity of 163 hp Equipped with a turbine from Mitsubishi, as a rule, its resource does not exceed 100-120 thousand km ( the axis is destroyed). Also, problems with the turbine control unit are possible ( varies assembly with turbine). The remaining engines are more reliable, but they suffer from leakage of oil from under the exhaust manifold, which leads to damage to intake dampers, and in the further engine. When using poor-quality fuels, prematurely ( on mileage 50-80 thousand km) fails the elements fuel system (nozzles, TNVD), as well as an EGR valve and a diesel filter.

Transmission

It can be equipped with such gearboxes - six-speed mechanics and automatic transmission. If we talk about the reliability of the transmission, then with careful operation and timely service, both boxes are practically not given any problems. In rare cases, troubles with automatic transmission are possible due to a failure in the control unit ( the clutch hangs). For example, it is worth noting that the problem is not serious and is solved by diagnosing and deleting an error. In mechanics weak place Clearance is considered. With medium loads, its resource is about 100,000 km, but if you use a car as a sports car, the clutch replacement may be required after 30000 km. Most BMW 3 series rear-wheel driven, but, all-wheel drive versions are found on the secondary market. The most common problem of such cars is a small resource. dispensing boxwhich fails at 80-100 thousand km of mileage. In most cases, for further use full drive, Distribution has to be changed to the new one.

Features and disadvantages of BMW 3 series suspension elements with mileage

The running BMW 3 series combines acceptable comfort and high level of controllability. Most of the details of the front suspension are made of aluminum, such a solution allows significantly reduced the weight of the car, but negatively affects the cost of repairing the chassis. If we talk about its reliability, then in this component the suspension "treshka" will not disappoint. Many owners complain that after 500,000 miles of run, when driving on a bad road surface from the suspension appears foreign noise (skyrp, knock). This feature is not a breakdown and eliminated by lubricant silent blocks. Otherwise, if you do not take into account the racks and bushings of the stabilizer ( change once in 30-40 thousand km), in the front axle, with careful operation, to 100-150 thousand km do nothing.

The rear suspension is also reliable. Only floating silent blocks, which are very often on mileage 80000, can be out of order. For the rear rubber, elevated tread wear is peculiar from inner. This is due to the fact that the wheels for increasing the stability are set by a house. In the steering, most often dislike Pump GUR ( have to change every 50-70 thousand km) I. steering Reika (begins to knock on a run of 60-80 thousand km, the replacement will cost 500 cu).

Salon

Traditionally, for most models of BMW, there are no complaints to the "treshka salon", and this refers to both the quality of finishing materials and the assembly. As for the reliability of the electrical equipment of the cabin, then it should be paid to the performance of the stove fan ( over time, starts whistling). The problem is solved quite simple ( motor machine lubrication needed), but to get to the fan will have to disassemble the floor of the cabin. Also, there are complaints of the radio ( ceases to catch a radio station). Causes questions and performance of the Central Castle ( ceases to react to remote control). To eliminate the problem will have to post about 200 cu. ( antenna replacement is required in the lid of the trunk or wiring, the problem is relevant for universal). If, on the instrument panel, the indicator with a yellow steering wheel caught fire, you must urgently contact the service. If this is not done, at the most inopportune moment the steering wheel can jam. In most cases, the disease is treated with a flashing of the control unit, but, there are often cases when owners have to study on the replacement of the electronic board.

Outcome:

In a used state, there are a number of sufficiently serious shortcomings with power units, to eliminate which, in most cases, you will have to lay out a cereal sum. However, if you are looking for stylish and fast carThe management of which gives true pleasure, then a more suitable option in this price segment you cannot find.

Advantages:

• Stylish design.
• High-quality finishing materials.
• Excellent driving characteristics.

Disadvantages:

• High cost of repair and maintenance.
• Elevated rear rubber wear.
• Problem force aggregates.

Reliability, problems and repair of the engine BMW N47

By car BMW 1-series in the Body of E87, in 2007, appeared diesel engine BMW N47, which replaced M47. Unlike its predecessor, a new lightweight closed aluminum block of cylinders with cast-iron sleeves, two balancing shafts and a cylinder diameter of 84 mm was used on N47. Inside the block there is a wrought crankshaft with a piston of 90 mm and forged connecting rods. Compression height of pistons 47 mm, and compression ratio 16.5. Together it gave a working volume of 2 liters.
On top of a block aluminum 16-valve head with two camshafts. The diameter of the inlet valves is 27.2 mm, the outlet 24.6 mm, and the thickness of the feet of the valve is 5 mm.
BMW N47 engines received injection system COMMON RAIL. And turbochards with an intercooler. Used turbine on the first versions (116 hp and 143 hp) is Garrett GTB1749VK with variable geometry.
Timing the timing chain and chain here is located behind the motor. The resource of the timing chain on the N47 is designed for the entire service life of the motor, but in reality there is no durability, about problems with the chain is written below. The exhaust gas recirculation valve is also applied, two-mask flywheel and Bosch DDE7.0 / DDE 7.1 control unit.

In parallel with this motor, a version with a working volume of 1.6 liters was produced - N47D16, as well as a 6-cylinder diesel N57.

Since 2014, the N47 engine is smoothly replaced with a more modern B47 diesel engine.

9. N47C20U1 (2011 - 2014) - version N47D20U1 for Mini Cooper SD.

Problems and disadvantages of the BMW N47 engines

1. Noise from the rear of the motor. The most famous disease of N47, which is caused by a stretched timing chain, its service life in practice about 100 thousand km. Often the problem arises much earlier. The solution is only one thing - the replacement and pull with this should not be otherwise happen. Additional trouble with the replacement of the chain on the N47 diesel is the need to remove the engine, because the chain is located at the back. In motors until 2009, the chain change together with the crankshaft.
2. Still extraneous sounds can cause the crankshaft damper, it serves about 100 thousand km, sometimes more, then requires replacement.
3. Vortex dampers. By analogy with M47, there are vortex dampers in the intake manifold, but the difference from the same M47, they cannot get into the engine. However, from the work of the EGR system, the dampers can be completely covered in Nagar. So that this does not happen, it is better to drown the EGR valve, and clean the dampers together with the collector or, even better, remove them and put the plugs. In order for the motor to work extremely adequately, after this operation, you need to flash the control unit without all this good.

In addition, overheating of this motor can lead to the formation of cracks in the block between the cylinders, which can be triggered, but the likely probability is that it does not help and have to look for a block of cylinders without cracks. The resource of turbines is about 200 thousand km, but maybe more.
The resource of the BMW N47 engine depends on the maintenance and if you cure disease on time, it may exceed 250-300 thousand km and more.
To reduce the likelihood of problems with the engine, it is advisable to change more motor oil, To use only the original manufacturer recommended by the manufacturer, also pour normal fuel, in time to be serviced and not to drive in full growth.

Engine tuning BMW N47

Chip tuning

To increase the power of his motor, it is enough to go to the tuning office and pour a new firmware. Refracting N47 at 116D and 118D in E87 and E90 bodies gives an increase in capacity of 35-50 hp Versions with an index 20d in E87, E90, E60, E84 and E83 bodies, can be decided to 210-220 hp Motor N47 TOP allows you to remove 240-250 hp using chip tuning
N47TU engines with a capacity of 116 hp and 143 hp Get the opportunity to get in a standard turbine 185-200 hp
Versions N47TU 184 hp Firm up in 215, and with a downpailer at 230 hp
The top N47S1 gives a chance to get firmware 240+ hp, and with a downpailer 280 hp

Probably disputes about what motors will never subscribe ever. All motorists are conventionally divided into several "camps", the largest of which are fans of German, Japanese and American brands. In this article we will look at the most successful, in our opinion, the Motors of BMW and talk about their reliability.

Among bMW owners You can easily find such who own a car with a real mileage of more than 500,000 kilometers, you can even meet such, on the speedometer of which there will be a mark of 1,000,000 kilometers. And this is not a myth, such engines really exist.

In the category of the best diesel units, we placed the M57 motor. This six-cylinder diesel has proven itself as very reliable and at the same time a rather dynamic power unit. It can be safely attributed to the change in the perception of diesel engines as "motors for pensioners", "Tractor motors for a taxi", etc. A bright example is the BMW 330D in the Body of E46, whose dynamics impressed without exaggeration.

M57 engines were produced from 1998 to 2008 in several modifications with power from 201 to 286 horsepower and installed on most models of those years. In addition, Range has been completed with these engines. Rover Vogue.. It is worth noting that the predecessor of the M57 diesel engine, the M51 motor, which stood on the conveyor from 1991 to 2000, did not differ as much reliability, although without difficulty "leaning" up to 500,000 kilometers without a boaronta.

The next place in the list we gave the V-shaped eight-cylinder M60 Motor. It should be immediately noted that V8 in the world aircraft has proven itself as powerful, but not very reliable engines, which, with difficulty "reach" without serious repair to a run of 500,000 kilometers. However, in the case of M60, BMW designers managed to make a breakthrough. Timing with a double row chain, thorough construction of construction and special nickel-silicon ("Nikasil") cylinder sputtering provided a large resource motor. There are documented cases when when there are mileage of close to 500,000 kilometers when it disassembled and the definite, there was no need to even replace piston rings. Of course, time takes his own, and today it is quite difficult to find a "alive" motor, but still real. During the operation of these engines in BMW, they decided to refuse Nikasil coating, which turned out to be sensitive to sulfur impurities in fuel, in favor of an improved coating "Alusil". M60 engines have been produced from 1992 to 1998 and installed on the BMW 5 and 7 series.

Most motorists are the phrase "row six" associated just with BMW. And one of the representatives of such engines that are distinguished by reliability is M30, the first modification of which saw the light back in 1968 and later stood on the conveyor until 1994.

M30 engine power ranged from 150 to 220 horsepower with a working volume of 2.5 to 3.0 liters. The reliability of this motor is explained by the simplicity of the design: the timing chain drive, the cylinder block, cast from the cast iron, the GBC from aluminum with two valves per cylinder. The safety margin laid into the M30 engine allowed Bavarian engineers to make its turbocharged version of M102B34, the power of which was 252 horsepower. To do this, the engine required a minimum amount of refinement.

M30 engines were equipped with BMW 5 and 7 series of several generations. With proper maintenance, these motors are easily passing to 500,000 kilometers without overhaul.

The M30 successor became the most "Legendary Six" - M50. The working volume of this motor ranged from 2.0 to 2.5 liters, and the power from 150 to 192 horsepower. As well as the predecessor, the cylinder block of this power unit was cast-iron, and 4 valves on the cylinder were used in the aluminum cylinder design. In addition, the late versions of the M50 engine began to equip the Vanos gas distribution phases system. As well as the other engines from this article, with timely maintenance of M50 without difficulty, "waders" to half a million kilometers without serious repairs. The new generation of this motor, which received the M52 index, despite the more complex design, retained the reputation of a reliable unit, but, as the time has shown, loses its predecessor in the resource and number of breakdowns.

As for modern turbochargers motors BMW, then allocate favorites among them, perhaps, early ...

To the restyling version of the BMW X3 Facelift 2014, a new generation of diesel engines was presented, which in subsequent years can become an integral part of the European Park car BMW. The B47 engine, as well as its predecessor N47, has four cylinders and 2.0 liters of working volume. Numerous enhancements were aimed at reducing fuel consumption and improving the sound of the motor. In one of the Interviews Christian Bok (Christian Bock), which heads the project of developing a new engine, disclosed information about many technical features new 4-cylinder diesel aggregatewhich is offered in options from 150 and 190 hp

It is impossible to overestimate the significance of the economical, but a powerful diesel engine for the European market. For example, Motor 520D not only longly dominates in the BMW 5 series, but also very popular in the 3rd series and models increased passibility X1 and x3. With the release in 2014. Restyling version of the BMW X3 F25 LCI, the previously used engine N47 will go to a well-deserved rest and will be replaced. new BMW. B47.

Like its predecessor, B47 has four cylinders located in a row, injection system with a common injection pipeline, 1995 cubic centimeters of a working volume and one turbocharger with a variable turbine geometry.

While N47 in the X18D and X20D variants possessed with a capacity of 143 and 184 hp, the new B47 offers 150 and 190 hp. The maximum torque in the case of a 150-strong version remains at 360 Newton meters at 1500-2250 revolutions per minute (earlier: 1750-2500 rpm). In a more powerful series, this figure increased from 380 to 400 nm at 1750-2250 rpm (previously: 380 nm at 1750-2750 rpm).
