Engine BMW B57D30

A series of 6-cylinder BMW B57 diesel engines with a volume of 3.0 liters has been assembled since 2015 and is installed on the most popular rear and all-wheel drive models of the German concern. There are three modifications of these power units: with one, two or four turbines.

The six-cylinder diesels of the modular series debuted in 2015 on the BMW 7-Series G11 and featured an aluminum block with plasma-sprayed steel on its cylinder walls, an aluminum 24-valve DOHC head with hydraulic lifters and a timing chain drive. The injection was carried out by a Common Rail fuel system from Bosch with piezo injectors.

In 2020, a series of 6-cylinder diesel engines was updated and the version with 4 turbines was abandoned. The remaining two modifications are now equipped with a couple of different-sized turbochargers and a new CR Bosch fuel system with injection pressure increased from 2500 to 2700 bar.

The engine was installed on:

  • BMW 3-Series F30, 3-Series G20;
  • BMW 4-Series G22;
  • BMW 5-Series G30;
  • BMW 6-Series G32;
  • BMW 7-Series G11;
  • BMW 8-Series G15;
  • BMW X3-Series G01;
  • BMW X4-Series G02;
  • BMW X5-Series G05;
  • BMW X6-Series G06;
  • BMW X7-Series G07.

Engine modifications with one, two and four turbines, with the first two still in two generations:

  • B57D30O0: 265 – 286 hp and 620 – 650 Nm;
  • B57D30T0: 320 – 340 hp and 680 – 700 Nm;
  • B57D30S0: 400 hp and 760 Nm.

Disadvantages of the B57D30 engine

  • The most famous problem of this diesel engine is the contamination of the intake manifold and its swirl flaps, which results in traction failures and unstable engine operation. In the most advanced cases, the axis of the dampers breaks and the collector has to be changed.
  • In general, the timing chain of engines of the modular series serves 200 – 250 thousand km and even more, but for powerful diesel engines with huge torque, replacements of up to 100,000 km are not uncommon.
  • The remaining problems concern almost any modern diesel engine: you need to carefully monitor the cleanliness of the cooling system, the quality of oil and consumables, and periodically clean the intake manifold and EGR system.
