The M57 engine number is located near the oil filter. The weight of the complete M57 engine is 210 kg. First generation of this diesel engine was equipped with steel intake swirl flaps, which could detach and fall into the engine cylinders, which usually resulted in a fatal outcome. With the upgrade, plastic flaps were introduced and they are relatively safe. The fuel system uses Bosch Common Rail system with electromagnetic injectors, which is highly reliable and has a long service life. It is important not to compromise on fuel quality and maintenance. On high mileage, leaks in the pressure regulator on the rail and failure of the main pump (sometimes it is sufficient to simply replace its filter) can occur periodically. The turbocharger itself is quite durable and does not cause much trouble, but problems with boost are usually related to cracks in vacuum tubes or a clogged pressure regulator. It should be noted that the turbocharger can leak oil if the crankcase ventilation is faulty. The timing chains of the engines from the first two generations last for a very long time, sometimes more than 500,000 km, but the engines of the third generation were upgraded and received a new timing drive, which may require replacement before reaching 300,000 km, and it is not cheap. Other malfunctions include occasional leaks in the plastic coolant pipes, thermostat failures, viscous fan clutch, damper pulley, or glow plug control unit. It is also worth noting that the second generation of the engine had a steel exhaust manifold and it often cracked, while the first and third generations were equipped with a cast iron manifold.
The three-cylinder BMW B37 diesel engine with a displacement of 1.5 liters has been fitted since 2014 and installed in front-wheel drive models as B37C15 and rear-wheel drive models as B37D15. In Mini cars, this diesel engine is known by its own index, B37C15A. Currently, the inline 3 engine line only consists of one family of engines.
2.0-liter diesel engine BMW M47, and later M47TU, was produced from 1998 to 2007 and installed in the most popular models of the company, such as 1-Series, 3-Series, 5-Series, and X3. There was also a version of this engine with the index M47R for Rover and Land Rover cars. Other four-cylinder engine options include: M41, N47, and B47.
The 2.5-liter BMW M51 diesel engine was produced at the factory in Austria from 1991 to 2001 and was installed in popular models such as the E36 body style of the 3 Series and the E34 and E39 body styles of the 5 Series. This power unit was modernized in 1996 and received a new index, M51TU. The inline-6 engine lineup also includes: M21, M57, N57, and B57.
6-cylinder BMW M57 diesel engines with a capacity of 2.5 and 3.0 liters were produced from 1998 to 2012 and were practically installed in all major models of the company at that time. There are three generations of these power units, commonly referred to as M57, M57N, and M57N2. The R6 line also includes engines: M21, M51, N57, and B57.
The 1.7-liter Nissan CD17 diesel engine was produced by the company from 1981 to 1998 and was installed in many popular models of that time, such as Sunny, Sentra, Pulsar, and AD. The turbocharged version of this engine, with a power output of 75 HP and a torque of 145 Nm, was used in the Stanza liftback. The CD series also includes the engines: CD20 and CD20T.
The 2.5-liter V6 Renault V4U engine was produced in Japanese factories from 2009 to 2019 and installed in the popular European sedan Latitude as well as its Korean counterparts Samsung SM5 and SM7. This engine is practically one of the clones of the second generation Japanese Nissan VQ25DE engine. The SCE line also includes: B4A, B4D, H4D, H4M, M4R, M5R, 2TR, and V4Y.
