Reliability, problems and repair of the BMW N57 engine

The year 2008 was marked by the release of another in-line 6-cylinder N57 turbodiesel, which was supposed to replace everyone's favorite BMW M57. The new engine used a closed aluminum cylinder block with cast iron sleeves and with an intercylinder distance of 91 mm, a forged crankshaft is installed inside the block with a piston stroke of 90 mm, a cylinder diameter of 84 mm,and the height of the pistons is 47 mm. As a result, we have a working volume of 3 liters.

They covered the block with an aluminum cylinder head, which is slightly lower than that of the M57 predecessor. Two-shaft head, 4 valves per cylinder, diameter intake valves 27.2 mm, exhaust 24.6 mm, valve stem diameter 5 mm.
To ensure the safety of pedestrians and increase the distance between the engine and the hood, the timing drive has been moved to back engine.
The timing chain on the N57 is single-row and lasts longer than on the 4-cylinder counterpart N47. The chain resource exceeds 200 thousand km.
The N57 uses a 3rd version common rail injection system, a CP 4.2 injection pump and, of course, a turbocharger with an intercooler is installed. The turbine here is a Garrett GTB2260VK with variable geometry that inflates to 1.65 bar.

This engine complies with Euro-5 environmental standards.

Like the M57, it uses a swirl flap intake manifold and an EGR exhaust gas recirculation system.The engine is controlled by a Bosch DDE7.3 ECU.

In September 2009, BMW 740d cars with the N57 TOP engine went on sale. It is equipped with a modified exhaust, piezo injectors and a two-stage turbocharging system, where the second stage has a variable geometry turbine and a boost pressure of 2.05 bar. Turbines here are BorgWarner K26 and BV40. Drives a Bosch DDE 7.31 motor.

Since 2011, the production of modified N57TU diesel engines began, which became a little more economical, received slightly modified combustion chambers, Garrett GTB2056VZK, solenoid injectors, and also began to comply environmental regulations Euro 6. The control unit here is Bosch DDE7.41.
Released in 2012 top variant from this series - N57TU Super or N57S, which was developed on the basis of N57 TOP. It was distinguished by a reinforced cylinder block, new pistons for a compression ratio of 16, a different crankshaft, an improved cylinder head cooling system, the strength of which was also increased. Inlet and outlet valves have been added in size (29.2 / 26 mm), camshafts have not changed. Also here is a new short intake system, piezo injectors and a modified fuel system with increased injection pressure, and the exhaust complies with Euro-6 standards. The N57S uses a Bosch DDE7.31 ECU.
The most important thing that distinguishes the N57S is three-stage supercharging: there are two BorgWarner BV45 and one B2 turbines, which allow you to get 381 hp. at 4000-4400 rpm and a torque of 740 Nm at 2000-3000 rpm.

In parallel with the N57, a related 4-cylinder diesel engine N47 was produced, which is a smaller copy of the N57 and, in addition to the absence of two cylinders, differs mainly in turbines, intake and exhaust.

Starting in 2015, the N57 is gradually being replaced by the newer B57 diesels.

BMW N57D30 engine modifications

1. N57D30O0 (2008 - 2014) - the very first N57 diesel. Its power is 245 hp. at 4000 rpm, torque 540 Nm at 1750-3000 rpm. They put this motor on the BMW 530d F10 and F07, 730d F01, X5 E70 and X6 E71.
For the BMW 325d E90, the torque has been reduced to 520 Nm.
2. N57D30U0 (2010 - 2013) - the weakest modification of the N57 with a Garrett GTB2260VK turbine. Engine power 204 hp at 4000 rpm, torque 450 Nm at 1750-2500 rpm. This motor is found on the BMW 325d E90 and 525d F10. This ICE was replaced with a 4-cylinder N47.
3. N57D30T0 (2009 - 2014) - the most powerful engine N57 which replaced the M57TU2 TOP. It develops 306 hp. at 4400 rpm, torque 600 Nm at 1500-2500 rpm.
They put N57 TOP on BMW X6 E71, X5 E70 and 740d F01. For the 535d F10 and 535d GT F07 cars, power has been reduced to 299 hp.
4. N57D30O1 (2011 - present) - an engine from the N57TU series, which replaced the N57D30O0. Power 258 hp at 4000 rpm, torque 560 Nm at 1500-3000 rpm. There is such a modification on the BMW 530d F10 / F07, 730d F01, 330d GT F34, 330d F30, 430d F32, X3 F25, X4 F26, X5 F15 and X6 F16.
5. N57D30T1 / N57TU (2011 - present) - replacement for the N57D30T0 model. Power reached 313 hp. at 4400 rpm, and a torque of 630 Nm at 1500-2500 rpm. This motor pleases the owners of 335d F30, 335d GT F34, 435d F32, 535d F10, 535d GT F07, 640d F13, 740d F01, X3 F25, X4 F26, X5 F15 and X6 F16.
6. N57D30S1 (2012 - present) - N57 engine with three turbines, which allow you to get 381 hp. at 4000-4400 rpm and a torque of 740 Nm at 2000-3000 rpm. Such an engine can be found in the BMW M550d F10, 750d F01, as well as the X5 F15 / E70, X6 F16 / E71 with the designation M50d.

Problems and disadvantages of BMW N57 engines

1. Swirl flaps. Unlike the M series, here they cannot fly into the engine, but they are able to coke so much that they stop moving, as a result of which the car will start to run unevenly and produce errors. The reason for this is the EGR valve, which needs to be periodically cleaned or programmatically removed, because often already at 100 thousand km the collector can be completely clogged with dirt.
2. Noises, extraneous sounds. As on the N47, the crankshaft damper fails here early (after about 100 thousand km) and needs to be replaced. After 200 thousand km extraneous sound from the back of the motor indicates the need to pay attention to the timing chain, it may need to be replaced.

The turbine resource is normal and is approximately 200 thousand km or more. In order for the motor to serve for an extremely long and trouble-free time, you should not delay changing the oil and use only high-quality engine oils, as well as regularly service your engine and pour good fuel. In this case, the resource N57 can greatly exceed 300 thousand km.

BMW N57 engine tuning

Chip tuning

Simple versions of the engine with one turbine of the N57 series (204 hp and 245 hp) with one block firmware are tuned up to 300 hp, and with a downpipe up to 320 hp. N57TU engines give 10-15 hp. more. These are the most profitable internal combustion engines for tuning.
The power of the N57 diesel with two turbines can be raised to 360+ hp. firmware and downpipe. Models with N57TU allow you to get about 380 hp. with the same set.
The most evil and perfect diesel engine N57S with firmware and downpipe can show 440 hp. and 840 Nm.

Strong foundation

Even today, mechanical components and parts form the basis of any engine operating on the Diesel principle. The task is to convert the chemical energy present in the fuel into motion using a thermodynamic process. As a result of the combustion of the fuel-air mixture, the piston receives acceleration. This rectilinear up and down movement of the piston is converted by the crank mechanism into rotational movement.

The block crankcase limits the combustion chamber and it also houses the crank mechanism.

In the cylinder head, gas exchange is exclusively controlled by valves and channels.

The physical principle of operation does not differ from the gasoline engine. The main difference from a gasoline engine operating on the Otto principle is the combustion process. In a diesel engine, fuel is injected directly into the combustion chamber (internal mixture formation). Due to the high degree of compression fuel-air mixture becomes very hot and its temperature reaches the ignition temperature. Combustion starts without the aid of a spark plug (self-ignition).

BMW diesel history

");w.show();" alt="(!LANG:mex_yz_vv_(1).jpg" title="mex_yz_vv_(1).jpg">!}
Rudolf Diesel and his engineRudolf Diesel patented his first engine internal combustion self-igniting in 1892. This large, slow-running engine was originally conceived for stationary use only. The labor-intensive design of the engine, the complex injection system resulted in a high production cost. First simple engines were not too comfortable and high-speed units. The harsh combustion process made the diesel engine, especially when cold, quite loud (due to knocking). Compared to a gasoline engine, it had poor power density and dynamics, and, in addition, a low liter power.

Only after using trucks and a number of improvements in the properties of materials and the manufacturing process managed to miniaturize it. Although the first car with a diesel engine was made already in 1936, it was necessary to wait until the 70s until the diesel engine was used as a real basis. car drive. The breakthrough came in the 80s when it was finally fully developed.

The diesel engine has become an alternative to gasoline. At this time, BMW decided to use it on their production models cars due to the improvement of its dynamics and acoustics.

");w.show();" alt="(!LANG:mex_yz_vv.jpg" title="mex_yz_vv.jpg"> !} BMW has been producing cars since 1929, and since then the demands on engines have been constantly increasing. BMW has always been innovative and technical details who were unparalleled in the world. This tradition continues in the field of diesel engines. The era of diesel engines began with the first production BMW engine in 1963.

1983

First introduced on the E28, the M21D24 was turbocharged on the 524td and had a displacement of 2.4 liters. Its prototype was the M20 gasoline 6-cylinder engine, and it developed a power of 85 kW / 115 hp. With. In this case, both engines could be assembled on the same conveyor.
Dynamic performance with a top speed of 180 km/h and acceleration from 0 to 100 km/h in 13.5 seconds set new standards for diesel vehicle dynamics at the time. This is why the 524td was given the title of "Sport Diesel.

History of diesel engines

Impressive innovations in the BMW 7 Series set it apart from other sedans executive class. Most Hi-tech are reflected in the new flagship of the Bavarian brand - this is a body made according to the Carbon Core principle using carbon fiber elements, BMW eDrive combined drive technology, gesture control, remote control parking with the interactive BMW Display Key and much more. Today, the most powerful 6-cylinder diesel engine in the world has been added to this list, which will be installed in two modifications - the BMW 750d xDrive and the BMW 750Ld xDrive. Consumption BMW fuel 7 series with an innovative powertrain is only 5.7 l / 100 km (5.9 l / 100 km in the case of the extended version), while the new engine develops an impressive 400 hp. maximum power and a torque of 760 Nm.

The new 3-litre inline 6-cylinder engine is based on the latest generation of powertrains. BMW units group. It features updated BMW technology TwinPower Turbo, including multi-stage turbocharging due to 4 turbochargers and an improved Common Rail direct injection system that supplies fuel to the cylinders at a pressure of over 2500 bar. All these changes have resulted in exceptional performance, excellent traction at all engine speeds and unsurpassed dynamics. New BMW The 750d xDrive improved its predecessor's performance by 0.3 seconds and now accelerates from 0 to 100 km/h in 4.6 seconds (BMW 750Ld xDrive in 4.7 seconds).

Efficiency on highest level: engine power improved by 5%, average consumption fuel reduced by 11%.

The outstanding new generation 6-cylinder diesel engine develops 400 hp. at 4400 rpm. Its optimized performance is most clearly reflected in the character of the increase in torque. The minimum 450 Nm is already provided at 1000 rpm, and the maximum 760 Nm of the power unit develops in the range from 2000 to 3000 rpm. Combined with an 8-speed automatic transmission Steptronic, the new motor allows the flagship sedan not only to quickly accelerate from a standstill, but also to accelerate intensively even at high speeds.

The most powerful 6-cylinder diesel engine from BMW has no equal speed characteristics and economy. Compared to its predecessor, engine power has been increased by 19 hp and torque by 20 Nm, while fuel consumption and emissions have been reduced by 11%.

Maximum efficiency at high boost pressure.

The best-in-class diesel engine from BMW is the pinnacle of German concern engineering. The unique solutions used in the manufacture of individual parts made it possible to achieve excellent power characteristics and engine efficiency. All engine components have an increased margin of safety and are able to withstand both increased thermal and mechanical loads. For example, maximum pressure in the combustion chamber increased from 200 to 210 bar.

The cylinder head and block are produced by hot isostatic pressing, which allows to achieve maximum strength of aluminum castings. The assembly process of the main bearings and the cylinder head is carried out using tie rods, the cylinder head gasket now consists of five layers, and the cylinders themselves are coated with a wear-resistant composition using the double-wire arc welding method. The pistons are made of aluminum alloy, have bronze piston pins and are centrally cooled with oil.

Exhaust gas cleaning system installed on BMW models 750d xDrive and BMW 750Ld xDrive, includes not only a diesel particulate filter and a nitrogen oxide catalytic converter, but also an SCR emission control system with urea injection.

The latest in turbocharger development from BMW: even more driving pleasure.

Thanks to multi-stage turbocharging and the coordinated work of all system components, the new engine has become even more efficient and productive. New boost system consists of two compact turbochargers high pressure integrated into a single variable geometry body, with the large turbocharger responsible for boost at low revs replaced by two smaller, more responsive turbochargers. Electronic system control system of the latest generation, which controls all engine parameters, coordinates the work of each turbocharger in a clear and harmonious manner.

In other words, one high-pressure turbocharger and two low-pressure turbochargers are constantly running. And only with a sharp acceleration from the revs idle move system disables both turbochargers low pressure, which contributes even more rapid increase boost pressure. The second high-pressure turbocharger is activated when the engine speed reaches 2500 rpm.

Another unique feature of the new engine is the exhaust gas recirculation system, which is active at both low and high boost pressures. This principle of operation can significantly reduce the level of emissions of harmful substances into the atmosphere.

The BMW 750d xDrive and BMW 750Ld xDrive models will be available from July 2016.

A six-cylinder diesel engine with four turbochargers was not for long the prerogative of the flagship BMW Seven: it appeared with this engine less than a year ago, and now the M550d model can boast of the same heart.

Recall that the three-liter B57D30C engine of the modular family became the world's first serial diesel engine with four superchargers. It has two low-response high-pressure turbochargers and two low-pressure "turbines" that come into operation in series. Moreover, one of the high-pressure compressors is connected only during intensive acceleration - and only after the crankshaft spins up to 2500 rpm. And piezo injectors inject fuel into the cylinder at a pressure of 2500 bar!

Compared to the previous three-turbine diesel N57 series, the maximum output has changed slightly: power has increased from 381 to 400 hp, and torque - from 740 to 760 Nm. However, traction is still limited by the capabilities of the current ZF eight-speed automatic: with the advent of a new gearbox, the restriction will be lifted and the peak torque will exceed 800 Nm. But the main advantage of the four-pressure circuit is different: 450 Nm of thrust are already available at 1000 rpm! The motor should spin up briskly from idle, although peak torque is achieved in the same range as its predecessor: from 2000 to 3000 rpm.

The all-wheel drive sedan BMW M550d xDrive with the new diesel accelerates from standstill to 100 km / h in just 4.4 seconds - 0.3 seconds faster previous model with a three-charged engine and only 0.1 s slower than the rear-wheel drive BMW M5 with a 560-horsepower biturbo-eight! The station wagon is less quick: 4.6 s to “hundreds”. The maximum speed is traditionally limited at around 250 km / h, and passport expense diesel fuel is reduced by 11% (for a sedan, on average, up to 5.9 l / 100 km).

Since the four-charged “five” belongs to the M Performance family, it has the appropriate insignia: M-body kit, sports suspension lowered by 10 mm, thruster on rear axle, 19-inch wheels, reinforced brakes and other exhaust system. In Europe, BMW M550d sedans will start selling from July, and station wagons will catch up by the end of the year. Nothing prevents us from bringing these cars to Russia, because we sell the “seven” with such a diesel engine.

AT this review showcasing BMW petrol and diesel engines that have been in use for the past 15 years. Due to the huge range of power units of the Bavarian company, we cannot cover all engines and their options. Nevertheless, we will dwell in detail on the most famous and popular motors.

BMW is one of the world's leading manufacturers, offering the most modern and advanced powertrains on the market. Therefore, you need to be prepared for large bills for maintenance and repairs. You don’t have to look far for examples - for many owners it comes as a surprise that the need to periodically replace the timing chain drive used in all modern engines bmw. The chain and tensioner, as a rule, take care of about 200-300 thousand km. This creates noise, and the engine runs unevenly. To replace the timing chain, it is necessary to prepare about 20-30 thousand rubles. In the case of older instances, difficulties arise when trying to conduct overhaul– the materials used for the manufacture of cylinder liners do not allow their restoration.

What expenses await you after buying a used BMW depends on the condition of the car and the version of the engine under the hood. Our review will certainly help to make right choice.

Multipoint fuel injection (ported)

Engines N42 and N46, produced from 2001 to 2007, are among the most popular four-cylinder BMW units on the secondary market, mainly due to the "troika" E46 and the Compact version based on it. These motors can be found in the "ones" E87 and "triples" E90 of the initial production period. It is believed that a BMW with a 4-cylinder engine is not a real BMW. But honestly, these little engines are unique. technical masterpieces. Both are equipped with a timing chain drive, both have a Double VANOS system - a system for adjusting the valve timing of intake and exhaust valves, as well as the Valvetronic system - an original solution for smoothly changing the height of the intake valves, replacing the usual operation of the throttle.

The main advantage of having a Valvetronic system is much more low consumption fuel (an average of 1.5 l / 100 km), compared with conventional engines.

Interestingly, the N42 and N46 engines perfectly perceive the transition to work on liquefied gas. The main thing is the right choice and professional installation of LPG.

Well-maintained 4-cylinder engines are low maintenance. Having picked up a copy with a real mileage of less than 200,000 km, you will be satisfied with your choice.

Faults due to LPG

Despite the fact that motors perceive the transition to liquefied gas operation without consequences, an unprofessional approach to selection and installation leads to sad consequences. Valvetronic does not tolerate amateurism, the result of which is damage to the cylinder head and burnt valve seats. Before buying a car with LPG, you need to visit a car service and check the condition of the engine.

In 2006 and 2007, a new era began for BMW enthusiasts. Exactly then German manufacturer updated the line of engines, introducing completely new engines into it. One of them is two modified engines: a 1.6-liter with 122 hp. - N43 B16 and 2-liter with 143 and 170 hp (N43 B20). Both motors received direct injection fuel. This means lower fuel consumption while maintaining high performance. But on the other hand, it means higher cost possible repair and the difficulty of installing LPG.

Operation and typical faults

N43 series engines are considered one of the most reliable among modern engines. BMW engines. They are ideal for those who have their eye on the BMW E90 and usually don't do many miles in a year. But still problems occur.

Valve train chain

There are cases premature wear timing chains. The problem concerns, first of all, cars assembled before 2009.

uneven work

Failure of the ignition system due to failure of the coils. Symptoms are accompanied by the illumination of the engine malfunction indicator.

Fuel pump failure

This malfunction often worries 6-cylinder engines, which will be described below. But sometimes fuel pump failure is encountered in earlier instances of 4-cylinder engines. Warning symptoms are starting problems and lack of traction in the upper rev range.

Engines of the M52 family debuted in 1994 on BMW 3 series E36 cars. M52 - further development reliable and powerful M50. The main difference is the use aluminum block, which allowed to reduce the weight by almost 20 kg. Together with lightweight connecting rods, chain tensioner and exhaust manifold the new engine has become lighter than its predecessor by almost 30 kg.

The M52 engine family is represented by engines with a working volume of 2.0, 2.5 and 2.8 liters, developing 150, 170 and 193 hp. respectively. S52 with 243 hp volume of 3.2 liters, installed on the M3 and intended for the market North America, is closely related to M52.

Released in 1998 year bmw 3 series E46 appeared updated engine M52TU. It is distinguished by the use of a variable valve timing system for intake and exhaust valves (Double Vanos system). In the first engines, the valve timing was changed only on the intake shaft. Engine power has not changed, but performance at low and medium speeds has improved.

Operation and typical faults

Engines of the M52 family are classics of the genre. It enjoys a good reputation for being durable and reliable, but does not tolerate harsh use and careless maintenance.

Breakdown of the cylinder head gasket and cracks in the cylinder head

Inline six-cylinder engines are sensitive to overheating: the long head can burst. AT best case pierce the head gasket. Troubles contribute frequent problems with cooling system pump and radiator fan drive. Ignoring the symptoms of overheating can lead to disastrous results when the most effective and cost-effective profitable way repair will be the acquisition of another motor in working condition.

Camshaft Position Sensor Malfunctions

Defect manifests itself uneven work engine and sluggish untwisting of the engine after warming up. Failure can also be accompanied by difficult starting - you have to turn the starter for a long time. Inexpensive analogues will cost less than 1,500 rubles, Siemens products are more expensive - about 3,000 rubles. Replacement is not difficult even for a non-specialized mechanic.

High oil consumption

In old age, the degree of wear of most engine elements increases. A considerable contribution to the oil consumption is made by exhausted valve stem seals.

Ignition coils

One coil for the M52 engine costs about 2000 rubles.

Application

Engines of the M52 family were installed both in small cars of the 3 and Z3 series, and in the flagship BMW 7 series.

The R6 M54 debuted in 2000 in three versions: 2.2, 2.5 and 3.0. All variants received a variable valve timing system for intake and exhaust valves (Double Vanos).

Owners praise not only the pleasant sound and good performance of engines (especially 2.5 and 3.0), but also reliability. However, don't rely on fuel economy.

The M54 engine disappeared from the offer list in 2007, along with the BMW E46 convertible.

Operation and typical faults

Serious malfunctions are rare and most often occur due to very long mileage, careless Maintenance and unprofessional repairs.

The only problem is over high flow oils. Losses occur as a result of oil waste and due to the specific design of the oil separator, which leads to clogging of the ventilation valve crankcase gases. As a result, it increases overpressure in the engine, which contributes to even higher oil losses.

Application

To save weight, the engine block is made of an aluminum-magnesium alloy. The Valvetronic valve stroke control system and the Double Vanos valve timing system are also used here. The engine that replaced in 2011 is a direct successor to the N52, but with a turbocharger and 4-cylinders - typical example downsizing.

Operation and typical faults

Noise of hydraulic lifters

The problem primarily concerns engines manufactured at the initial stage of production - before November 2008. Subsequent engines received a redesigned cylinder head.

Diesel engines

2.0 dM47

Short description:

Turbocharging

4-cylinder

16 valve

The power unit with the code designation M47 is a 2-liter diesel engine used from 1998 to 2007. It is interesting that two generations of 2-liter diesel engines are hidden under the M47 code: the first generation - until 2003 with a working volume of 1951 cm3, and since 2001 a new generation with a working volume of 1995 cm3. The first M47 was with a high-pressure fuel pump, and the second with a Bosch Common Rail injection system.

The 2-liter M47 can be found both in models marked "18", for example, the BMW 318d, and marked "20", for example, the BMW 320d. With the same working volume, they differ in equipment and developed power. M47 1951 cm3 was also used by the English Rover in Land Rover Freelander, MG ZT and Rover 75.

Along with the increase in capacity, the engine received balancer shafts. The turbocharger, instead of vacuum control, acquired a more accurate electric one. A good torque curve has been obtained by using variable geometry intake manifold: dampers regulate the air flow depending on the engine speed. Each version of the M47 has chain drive Timing, and in this series of engines, unlike the N47 receiver, it is placed in an easily accessible place - in front of the engine. All M47s have a dual mass flywheel, and the latest examples can be equipped with a DPF filter.

Operation and typical faults

M47 engine advanced in technical terms and sometimes causes difficulties for mechanics with the correct conclusions in the diagnosis. However, compared to the N47's successor, it should be seen as less problematic and more successful motor. Versions with power from 143 hp provide excellent performance, and at the same time quite economical. For example, a 163-horsepower 320d consumes an average of about 6.6 l / 100 km.

Destruction of the intake manifold flaps

it typical fault many BMW diesel engines, including those with six cylinders. The dampers responsible for changing the geometry of the intake manifold can become loose and fly off the axles, hitting directly into the engine. This leads to damage to the cylinder head (destruction of the combustion chambers), the turbocharger, and sometimes the pistons.

Premature failure of the turbocharger

Longer oil change times are often blamed for low turbocharger life. To prolong its life, it is better to shorten the prescribed oil change intervals. Since the turbocharger is electrically controlled, not all turbine remanufacturers can adjust it correctly after repair. However, it is technically possible.

Pulley wear

The source of suspicious knocks from the engine is often a delaminated damper pulley responsible for the drive attachments. However, sometimes a dual-mass flywheel located on the other side of the engine makes a similar noise.

Application

In view of the large power range, the M47 series engine was installed in compact bmw 1 series, X3 crossover and even in the BMW 5 series.

Among similar turbodiesels of its age, the M47 excelled technically and in terms of performance. This is a very successful engine, although you should not count on the cheap cost of operation. It has a range technical solutions that require high costs for service. However, the engine cannot be described as very problematic.

Alternative

Among BMW diesel engines, in principle, there is not much choice, except perhaps for the 2-liter M47. The rest of the engines are much more powerful.

16 valve

Common rail injection system

Compact, mid-range and SUV models

In March 2007, BMW launched a new generation of two-liter N47 diesel engines on the market. The design of the engine has changed fundamentally: the cylinder block is made of aluminum alloy, which saved 17 kg, the timing drive was moved from the front of the engine to the rear - to the flywheel. Most of the engines in this series were equipped with a braking energy recovery system, the so-called Efficient Dynamics.

All N47 series engines from 163 hp have a piezoelectric Common Rail injection system with an operating pressure of 1800 - 2000 bar. More weak engines equipped with electromagnetic nozzles with a working pressure of 1600 bar. Since the new engine has more torque than the M47, the crankshaft had to be reinforced. Very interesting versions with a capacity of 204-218 hp, which are sequentially boosted using two turbochargers various sizes. This is the most powerful 2-liter turbodiesel in the world. In 2013, the N47 appeared with a working volume of 1598 cm3 with a reduced pitch and cylinder diameter and a different block design. He received the designation 14d, and his power is 95 hp.

Operation and typical faults

The N47 diesel, in terms of performance, is very economical engine. Performance, minimal vibration and pleasant sound deserve high marks. Powerful torque, available already from low revs, suggests that even large and heavy vehicles, such as 520d and X3, will not experience any problems with dynamics. The BMW 520d F10, weighing over 1600 kg, is content with an average of just over 7 l/100 km, which is very good result. N47 in terms of fuel consumption is more economical than its predecessor M47.

Timing imperfection

Located in an inconvenient place for maintenance, the timing chain drive proved to be extremely unreliable. A poor-quality lower sprocket quickly wore out the teeth, which led to chain damage. Noise from worn parts could appear after 60,000 km. AT extreme cases it came to jumping the chain or breaking it. Theoretically, the manufacturer resolved the issue in 2010, but opinions about achieving a positive result are contradictory. There are cases when, after a warranty replacement of the timing chain, the alarming noise reappeared - approximately after 150,000 km.

intake manifold flaps

The problem is similar to the one that exists in the M47: the flaps become loose, fly off and fall into the engine, damaging it and the turbocharger.

Piezoelectric nozzles

They are used in high power engines. Nozzles of this type cannot be restored, therefore, in the event of a malfunction, the owner will face high costs. Under normal operating conditions, the nozzles confidently go more than 200,000 km.

Application

Since March 2007, the engine has gradually replaced its predecessor. AT new version"five" 2-liter biturbo replaced the 6-cylinder diesel 525d.

Common rail injection system

Turbo or biturbo

Models of the middle class and above, and SUVs

The M57 engine family with common rail injection system debuted in 1998, i.e. less than a year after the introduction of the first diesel engine with a CR system for stock car Alfa Romeo 156. The BMW diesel has received numerous engine of the year awards in its category. Other manufacturers also used this power unit: the 2.5-liter version of the M57D25 fell into Opel Omega, and a more powerful version in the Range Rover.

Diesel with the designation M57 has a cast iron block, 6 cylinders in a row and an aluminum head with two overhead camshafts. Power is provided by a high-pressure pump, a fuel rail and nozzles - depending on the year of manufacture, electromagnetic or piezoelectric.

During the production process, its design changed several times: in later models, designated M57N and M57N2, the timing chain drives only one camshaft, and the moment is transmitted to the other camshaft through gear reducer. Modifications were also sequentially introduced with electric control turbine blades, a new generation common rail injection system with higher operating pressure and a particulate filter. The top version M57TU2D30 has two turbochargers and 286 hp.

Operation and typical faults

The first versions of the M57 engine are considered not to be killed. There are cases when a BMW 5 Series with this engine drove 1,000,000 km without a major overhaul.

flaps in the intake manifold

More powerful versions M57 engines are equipped with a system for changing the length of the intake manifold. Weakening of the dampers and their "spanking" is the most common ailment of the M57. An experienced mechanic will determine the presence of a defect by ear. Many resort to the removal of dampers, but this is not recommended. The prevailing opinion of the majority that after the removal of the shutters the engine works the same way is not entirely accurate. The engine reacts worse to gas in the lower rpm range. The cost of restoration of dampers is from 5000 rubles and more.

Pulley damage M57 N

AT upgraded version engine with index N, the attachment drive pulley installed on the crankshaft. This may cause damage to units such as the air conditioning compressor.

fuel injectors common rail

In early versions of the engine, they were durable, but later, from about 2003, the resource was significantly reduced and amounted to just over 100,000 km. In older versions, Bosch solenoid injectors are remanufactured. In later ones, especially biturbo, only a replacement. The price of 12,000 rubles apiece is quite reasonable, especially since we are talking about a car of an expensive and prestigious brand.

Intake manifold rupture

Met only in the engines of the very first batches.

Application

The M57 engine is mounted longitudinally at the front, and the torque is transmitted to the rear wheels or two axles in xDrive versions, where the front wheels receive the necessary traction through the driveshaft.

Its block is made of aluminum, which is likely to affect its durability in the future. The common rail injection system operates at pressures up to 2000 bar. The N57 is the first production triple supercharged engine: this version of the engine, developing 381 hp, was designated N57S. After such a supercharged biturbo engine, you will not surprise anyone. N57 engines are very often combined with all-wheel drive. Only an 8-speed "automatic" is installed in a pair of the motor. All N57s have a particulate filter.

Operation and typical faults

chain rattle

This problem is becoming more and more acute, and BMW does not cover the costs in the post-warranty period. Long intervals between oil changes adversely affect the condition of the tensioner and the chain itself.

The appearance of soot

Owners report that the N57 engine is prone to carbon deposits in the intake ducts. In some cases, already at 70-80 thousand kilometers, it was necessary to disassemble the engine to clean it.

Application

Aluminum N57s are gradually replacing the old M57s. The engine is not used in cars of other brands.
