N57D30OL is a world-famous diesel-powered engine, which is used for BMW 3-series cars, as well as the BMW X3 model.

The working volume of the power unit is 3.0 liters. If to be as accurate as possible, it is 2993 cubic centimeters. As for the power, here the indicator is equal to 245-258 horsepower. However, despite such outstanding technical characteristics, the described engine also has a very economical fuel consumption. To tell an approximate figure, it is necessary to find out, on what terrain mainly you will operate your car. For example, if it is busy city roads with traffic jams and other “charms” of modernity, then for 100 kilometers you will lose about 7-8 liters. If it is a matter of moving along highways outside populated areas, the figure will be significantly reduced and will be equal to approximately 4 liters. However, mostly people have to drive the car in mixed terrain, and in this case, the consumption per 100 kilometers will be equal to 5-6 liters.

Based on the characteristics of fuel consumption, many readers may have a question about how much oil this engine consumes per 1000 kilometers. The exact figure is also not to reveal, but the approximate parameter will be equal to 50-700 grams.

In general, the described motor is universal, it will perfectly suit any driver, regardless of his initial goals. If you live a measured life, you go to work in the morning and return home in the evening, and at weekends you have the opportunity to go to the dacha – this engine will be perfect for you. Even if you are a fan of high speeds and long trips – the situation in general will not change.

Advantages

If to characterize the described motor in one word, it can be confidently called reliable. The engine resource will easily exceed 300,000 kilometers, if you take proper care of it, maintain normal operating conditions and get rid of possible problems in time.

In addition to this, we can consider the combination of outstanding power and also an impressive fuel consumption figure.

Disadvantages

In general, the car is quite reliable, however, if you delve properly into the reviews of real car owners who have faced problems associated with the described engine, you can realize that here too, it was not without shortcomings. Immediately I want to say that the problems in this case are not very serious. All of them are easily solved independently, however, if you have the proper level of skills. Otherwise, we strongly recommend that in any situation that arises, contact specialists who will provide you with qualified assistance. Otherwise, you may encounter complications, which may later completely “kill” the engine.

Below we will list the most common problems and tell you how to deal with them:

  • Sometimes you may hear various sounds of extraneous origin. For example, an annoying noise, unpleasant to hear, coming from the side of the engine. As with the N47, the problem is most likely the crankshaft damper, which fails after about 100,000 kilometers. A replacement part should be performed. It is also likely that after 200,000, you will hear foreign sounds coming from the rear of the powertrain. What does this mean? Most likely, it is time to replace or at least check the condition of the timing chain.
  • If in the case of M-series engines, the vortex flaps could “fly” into the engine, here they can become caked to such an extent that they simply stop moving. Further consequences can be very different, including uneven operation of the car as a whole. The most common source of the problem is the EGR valve. You will have to clean it from time to time. Otherwise, you can remove it, because after 100,000 kilometers, the manifold is able to completely clog with dirt.

There are no other notable problems. As we have already mentioned, this power unit is characterized by reliability and with proper operating conditions and timely diagnostic procedures will serve you for a very long time.

Chip Tuning

Despite the fact that the power indicator in the case of the described motor is quite high, some car owners do not know the limits. Are there ways to increase the number of “horses”? Of course yes. But to what limits will it be possible to reach? With the right firmware and downpipe – over 300 hp.

This engine is installed on the following models:

BMW X3 (F25)

BMW X5 (F15)

BMW X5 (E70)
