What it covers

A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.

B57 DIESEL ENGINE - CHECK CONTROL MESSAGE OIL LEVEL TOO HIGH. Check Control Message (CCM) "Engine oil level too high" is displayed. Fuel dilution into the engine oil due to the diesel particulate filter (DPF) regeneration strategy.
