BMW B57 engine overview
The BMW B57 engine is a 3.0-litre twin-turbo diesel used in modern BMW models from roughly 2015 onward — including 530d G30, X5 G05, X7, 640d, and some 435d applications. If you search for B57 or BMW B57 engine, you need a unit with the correct suffix (B57D30, B57C30, etc.) matched to your VIN and emissions hardware.
Bavarian Engines stocks tested B57 engines for sale with documented codes, mileage, and EU shipping from Hamburg.
Common B57 engine codes
- B57D30 — standard twin-turbo 3.0 diesel (265–286 hp variants)
- B57C30 — related six-cylinder family with different calibration
- B57B30 — higher-output applications (verify per VIN)
Suffix letters control turbo layout, AdBlue/SCR hardware, and ECU maps. Never assume interchangeability without VIN confirmation — we verify free of charge before you pay.
