BMW N57 engine reliability, problems and repair

The year 2008 was marked by the release of the next inline 6-cylinder turbodiesel N57, which was supposed to replace the beloved BMW M57. New engine used a closed aluminum cylinder block with cast iron liners and an inter-cylinder distance of 91 mm, a forged crankshaft with a piston stroke of 90 mm, a cylinder diameter of 84 mm, is installed inside the block,and the piston height 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 its predecessor M57. Twin-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 to increase the distance between the engine and the bonnet, the timing has been moved to the rear of the engine.
The timing chain on the N57 is single-row and lasts longer than on the 4-cylinder N47 sibling. The chain resource exceeds 200 thousand km.
The N57 uses the 3rd version of the Common rail injection system, the CP 4.2 injection pump and, of course, a turbocharger with an intercooler. The turbine here is a Garrett GTB2260VK variable geometry turbo that inflates to 1.65 bar.

This engine matches environmental standards Euro 5.

As on the M57, it uses intake manifold with swirl flaps and EGR.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. The turbines here are BorgWarner K26 and BV40. Drives the Bosch DDE 7.31 motor.

Since 2011, the production of modified N57TU diesels began, which became slightly more economical, received slightly modified combustion chambers, Garrett GTB2056VZK, solenoid nozzles, and also began to comply with Euro-6 environmental standards. The control unit here is Bosch DDE7.41.
In 2012 was released top option from this series - N57TU Super or N57S, which was developed on the basis of the 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. The intake and exhaust valves (29.2 / 26 mm) were added in size, the camshafts did not change. Also here is a new short intake system, piezo injectors and a redesigned fuel system with increased injection pressure, and the exhaust meets Euro-6 standards. The N57S uses a Bosch DDE7.31 ECU.
The most important thing that distinguishes the N57S is its three-stage supercharging: there are two BorgWarner BV45 turbines and one B2 turbine, which produce 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 N47 was produced, which is a smaller copy of the N57 and, in addition to the absence of two cylinders, is mainly distinguished by 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 diesel N57. Its power is 245 hp. at 4000 rpm, torque 540 Nm at 1750-3000 rpm. We installed this motor on 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 turbo. Engine power 204 HP at 4000 rpm, torque 450 Nm at 1750-2500 rpm. This engine is found on the BMW 325d E90 and 525d F10. This internal combustion engine was replaced by 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.
We installed N57 TOP on BMW X6 E71, X5 E70 and 740d F01. For cars 535d F10 and 535d GT F07, the power is 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 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 of the N57D30T0 model. Power reached 313 hp. at 4400 rpm, and a torque of 630 Nm at 1500-2500 rpm. This motor pleases 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 provide 381 hp. at 4000-4400 rpm and a torque of 740 Nm at 2000-3000 rpm. Such an engine can be found in BMW M550d F10, 750d F01, as well as X5 F15 / E70, X6 F16 / E71 with the designation M50d.

BMW N57 engine problems and malfunctions

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 work unevenly and give errors. The fault is the EGR valve, which must be periodically cleaned or programmatically removed, because often already by 100 thousand km the collector can be completely clogged with dirt.
2. Noises, extraneous sounds. As in the N47, the crankshaft damper breaks down early here (after about 100 thousand km) and asks for replacement. After 200 thousand km extraneous sound from the back of the motor informs about the need to pay attention to the timing chain, it may need to be replaced.

The service life of the turbine is normal and is about 200 thousand km or more. In order for the engine to serve as long as possible and without problems, you should not delay changing the oil and use only high-quality engine oils, and also regularly service your engine and pour good fuel. In this case, the resource of 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 provide 10-15 hp. more. These are the most profitable ICEs for tuning.
The twin-turbo N57 diesel can be bumped up to 360+ hp. firmware and downpipe. Models with N57TU generate around 380 hp. with a similar set.
The most evil and perfect N57S diesel engine with firmware and downpipe can show 440 hp. and 840 Nm.

For many decades, the German concern BMW has produced only cars, but since 1999 the company started producing crossovers, and the first model produced was the X5 car in the back of the E53. The first BMW X5 diesel appeared in 2001 - it was a car with a three-liter 184-horsepower M57 engine.

As of March 2016, only the 5th series of Bavarian SUVs are represented by three generations in bodies:

  • E 70;

Diesel cars X5 are practical and good dynamics, but they have both advantages and disadvantages, and they will be discussed in this article.

BMW X5 E53 diesel

Traditionally, diesels are considered to be noisy and not designed for high speed, but on the other hand they are high-torque and economical. The BMW concern decided to prove that this is not entirely true - and indeed, "Bech" diesel engines operate with low noise and almost without vibrations, and have good speed qualities.

The BMW X5 E53 crossover was first equipped with a diesel engine in 2001, but the M57 ICE itself has been produced since 1998, it is one of the best power units in the diesel line. BMW motors... The M57D30 engine is an in-line six-cylinder turbodiesel with a cast iron cylinder block and an aluminum block head, 4 valves per cylinder. On this engine, the Common Rail injection system was first used, in which the fuel injection pressure does not depend on the number of revolutions of the internal combustion engine. The M57D30 was also installed on BMW vehicles:

  • 530 E39;
  • 330 E46;
  • 730 E38.

In 2003, the M57D30 diesel engine on the X5 crossover was replaced with a newer M57TUD30 power unit, while the same cylinder volume (3.0 liters), the engine power increased by 34 hp. with.


BMW X5 E70 diesel

The BMW X5 E70 is the second generation of the popular German SUVs, this model was produced from 2007 to 2013. On pre-styling crossover BMW X5 E70 diesels came with a volume of 3.0 liters in two versions:

  • M57TU2D30-OL (3.0d) - 235 HP with.;
  • M57TU2D30-TOP Turbocharged - 286 HP with.

Since 2010, the line of diesel engines on the X-Fifth has been updated - instead of the M57 series engines, N57 diesel internal combustion engines have been installed. Motors of this family, depending on the modification, have a different number of turbines; fuel injection into the cylinders is supplied under different pressures. In the restyled version of the BMW X5, the power of the internal combustion engine 30d has been increased from 235 to 245 hp. with., and in the version of the diesel engine with double turbocharging (40d) - up to 306 liters. with.

BMW X5 cars with 3.0 diesels are found on Russian roads infrequently - such crossovers were not officially sold in Russia, mainly these cars were brought in from Europe. Often potential buyers face a choice - buy a BMW X5 with a diesel or gasoline engine. The advantages of BMW diesels are obvious:

  • low fuel consumption;
  • good dynamics;
  • high reliability.

But on BMW cars The X5 with diesel engines has many different problems. One of the diseases of all modern diesel engines is clogging particulate filter... This element of the exhaust system goes about about 100 thousand km without problems, then it starts to clog. Replacing the particulate filter is very expensive, as an option, it can be cut out, but in this case, you will need to rewrite the control unit.

Still all diesel internal combustion engines are very critical to quality. engine oil and diesel fuel, but if the car is operated with care (undergo maintenance on time, do not overload or overheat the engine), the power unit can last a long time, and it will not cause trouble to the car owner. M57 series motors have the following characteristic faults:

  • nozzles are clogged, especially often this problem occurs on an internal combustion engine after 2003;
  • The gas recirculation valve "dies";
  • cracks form in the exhaust manifold;
  • on a run of 200-250 thousand km, the turbine fails;
  • vortex dampers break, the consequences can be sad - the pistons are broken by fragments, the surface of the cylinders is lifted.

Engines of the N57 series run quite quietly, if the hood is not opened, you might think that a turbocharged gasoline engine is installed. The vibration of the three-liter N57 diesels is small, they work smoothly. Without problems, these motors nurture at least 200 thousand km, the further fate of the internal combustion engine depends on the operating conditions - in principle, they can last 500 thousand km or more. BMW diesels have one important advantage over gasoline engines - they consume less oil. If a gasoline engine already on a run closer to 50 thousand km begins to "gobble up" oil, then a diesel internal combustion engine can hardly consume oil during its entire service life.


BMW X5 diesel fuel consumption

Diesel Engines is always more economical than gasoline engines, and as in all other car models, fuel consumption on BMW X5 with diesel engines largely depends on operating conditions, driving style, and season. In winter, fuel is additionally spent on warming up the engine; in urban conditions, diesel fuel is always consumed more. The transmission also matters - on a car with automatic transmission gears fuel consumption increases compared to a car on "mechanics".

On the BMW X5 E53 crossover with a 3-liter diesel engine, the average consumption on the highway is 8-10 l / 100 km (depending on the firmware of the control unit), in the city - from 12 to 16 l / 100 km. For motors 40d in technical characteristics the consumption per hundred kilometers is indicated as 5.8 liters on the highway and 7.1 liters in the city.

BMW X5 cars with diesel engines have a good acceleration - up to "hundreds" they accelerate no worse than cars with gasoline engines of the same size. Car owners "X-Fifths" like the excellent dynamics of the crossover, good handling, economical consumption fuel. Diesels of the N57 series turned out to be more advanced in terms of operational characteristics:

  • easier to start in frost, at almost any subzero temperature;
  • accelerate as quickly as gasoline engines;
  • at idle, they work smoothly, practically without vibrations.

If the car with the N57 diesel is operated carefully, the turbine can last a long time. Another positive point - almost all diesel X5 are equipped with starting heater Webasto. The heater increases comfort - passengers always get into a warmed-up car, moreover, warming up saves engine life.

Car owners also note the cons of diesels:

  • such power units are good until they break down, and if repairs are required, then it is expensive;
  • motors are demanding on the quality of fuel, engine oil.

The M57 ICEs are famous for their long service life; in some cases, diesel engines could drive even a million kilometers without overhaul. The car owners note few drawbacks of these power units, the main faults are:

This is not to say that problems are encountered quite often, but the problems listed above are the most typical for the M57 internal combustion engine. In general, there are good reviews about BMW X5 cars with a diesel engine, and disadvantages, if desired, can be found in any car model.

The Bavarian concern equips its crossovers and sedans, station wagons with diesel power units... The line of these BMW engines is one of the best in the world. One of the main advantages is the reliability of the unit, excellent wear resistance of the catch. But as practice shows, the repair of diesel BMWs is not uncommon. Vulnerable engine parts include liners and piston rings, which rarely withstand more than 300 thousand km. Timely diagnostics will allow you to postpone engine repairs for a long time, because not only mileage affects the condition of the engine, but also the specifics of operation, timely maintenance and the quality of the oil used.

The six-cylinder diesel engine with four turbochargers was not the prerogative of the flagship BMW for long: 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-inertia turbochargers. high pressure and two "turbines" of low pressure, which come into operation in series. Moreover, one of the high-pressure compressors is connected only during intensive acceleration - and only after the crankshaft has spun to 2500 rpm. And piezo injectors inject fuel into the cylinder at a pressure of 2500 bar!

Compared to the performance of the previous three-turbine diesel engine of the N57 series, the maximum output has changed slightly: the power has increased from 381 to 400 hp, and the torque - from 740 to 760 Nm. However, the thrust is still limited by the capabilities of the current eight-speed "automatic" ZF: with the advent of new box gear limitation will be lifted and the peak torque will exceed 800 Nm. But the main advantage of the four-supercharged circuit is different: 450 Nm of thrust is available already at 1000 rpm! The motor should revive vigorously with idle speed although peak torque is reached in the same range as its predecessor: from 2000 to 3000 rpm.

The all-wheel drive BMW M550d xDrive sedan with the new diesel accelerates from standstill to 100 km / h in just 4.4 seconds - 0.3 seconds faster than the previous model with a triple-aspirated engine and just 0.1 seconds slower than the rear-wheel drive BMW M5 with a 560-horsepower biturbo-eight ! The station wagon is less agile: 4.6 seconds to "hundreds". Maximum speed traditionally limited at around 250 km / h, and the passport consumption of diesel fuel has been reduced by 11% (for a sedan, on average, up to 5.9 l / 100 km).

Since the four-aspirated "five" belongs to the M Performance family, it has the corresponding insignia: an M-body kit, a sports suspension lowered by 10 mm, a steering mechanism on the rear axle, 19-inch wheels, reinforced brakes and a different exhaust system. In Europe BMW sedans The M550d will start selling in July, with station wagons moving towards the end of the year. Nothing prevents you from bringing these cars to Russia as well, because a G7 with such a diesel engine is on sale here.

They often ask the same question on the topic "what does BMW have with diesels?", Or "which diesel should I buy?"
Take a short essay on "Diesel in BMW" instead of answering.

The diesel internal combustion engine has a higher efficiency in the full output mode and a noticeably higher efficiency in the partial load mode and idle move... The gasoline engine is hampered by the principles of its operation - the presence of a throttle, the formation of a mixture outside the combustion chamber, the impossibility of working on lean mixtures. The partial load mode for him is inconvenient and extremely harmful. In this sense, the gain of the diesel engine is absolute.

- its average temperature is noticeably lower, and in the mode of partial loads and idling, a modern diesel engine may not even warm up to the nominal operating temperature at all. Thanks to these features, the diesel engine is almost not afraid of traffic jams, and even more so - of idling: it is not so scary to use it with a daily traffic jam start-stop. The heat emission of a diesel (turbodiesel) is not only lower, but also "smarter" - the presence of a turbine is almost a guarantee that in a traffic jam you do not load the engine with excessive power - by low revs it hardly works.

In the dry residue, from the point of view of the load on the oil, which, by the way, in diesel engine is always about 20% more than in a gasoline counterpart of a similar displacement, diesel is qualitatively superior to gasoline engine.

You can also recalculate, for example, the power allocated on average per oil volume, etc. - in all this, the diesel internal combustion engine wins with a margin and "for a clear advantage." And if you also remember the "traditional" conservative habits and the fad to change the oil in a diesel engine every 7-10 thousand run (well, of course, we have "dirty diesel fuel" - and about EURO5, advertising is blatantly lying to us, and the oil is already already " black "is), then diesel, from the point of view of the expected resource, is almost eternal even in the conditions of Russian operation. Let's add here a few more possible factors characterizing the likely favorable conditions for the movement of such cars - often diesel engines are bought by those who travel far and at a high average speed ...

Total: a modern diesel engine is significantly different from a modern one. gasoline engine in terms of the expected resource precisely due to a successful coincidence technological features... Below I will tell you exactly how much.

Now the questions that are often asked about this topic:

How modern are BMW diesel engines?
BMW makes some of the highest quality and most modern diesel engines - they are economical, powerful and reliable. In the most modern options, they are also very quiet, which cannot be said about most of the competitors. For the last 20 years, BMW has been doing nothing but transforming its successful gasoline engines "into diesels", trying to get "ecology and economy" out of them through monstrous technological tricks. The results, apart from winning a competition such as "Engine of the Year", are in fact deplorable. But the design of the diesel engine is devoid of a huge amount of technological and environmental debris: VANOS, Valvetronic, controlled thermostat, and so on. Diesel engines are only just being improved in technology, with minimal environmental problems. At the time of 2012, in the petrol / diesel battle, diesel unconditionally wins.

What can you say about specific models?
M21 - never seen.
M51 - I saw a couple of times, a regular condo tractor.
M57 - great option for X5. On a sedan it seems strange to me, although this is a matter of taste.
The N57 is a quiet, almost petrol-feeling diesel engine. If not for the short rev range, it would be difficult to distinguish from a gasoline turbo engine.
The N47 / M47 are loud but very economical motors. There are seemingly already solved problems with the timing, which are not at all easy to solve, if, nevertheless, you are faced with them. Either way, this is a choice to save money.

Are there any statistics?
A complete measurement and inspection of diesel internal combustion engines requires the dismantling of the injectors. This is not a quick or cheap procedure. I do not have statistics of measurements on these motors, and in principle there are not many references to them. The reasons are explained in the next paragraph.

Resource?
Even with an unsuccessful "recommended" oil and equally unsuccessful analogues of this oil, you run the risk of leaving without problems 200-250 thousand km and even more... And this is practically without oil consumption and on almost any of the BMW diesel engines. On condition, of course, that the motor was not overheated and was operated normally. Subsequently, the problems will arise approximately the same as those of the gasoline counterparts. The processes in the CPG there are completely similar, they just happen more slowly and the threshold of visibility, thus, is postponed to guaranteed 5-7 years of completely comfortable operation. The more your annual mileage and the higher the average speed, the further the moment of the onset of problems with oil consumption is postponed. What the owner of a gasoline engine should worry about already at a mileage of 40-60 thousand (!), Its diesel counterpart may not disturb at all during the time of owning a car.

Problems?
I think the main problem is the fuel equipment - it is really not cheap for a diesel engine. One filling "with sand" and repairs can unpleasantly surprise you with its cost. However, if you use "standard" oil, problems will certainly appear in the above interval, just the majority will not even consider them to be problems. The vast majority of petrol BMW owners show no signs of anxiety at all up to an oil consumption of 1 liter per 1000 km.
In the case of a diesel engine, which during the first years of operation, most likely, will not consume oil at all, the owner will not be afraid of any 1, 2 or even 3 liters per 10,000 km. Most likely, the logic "well, thanks for holding out for 5 years, and now you can forgive" will work, instead of the reasonable logic "I did not eat at all, why did I start now?"
