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.

TRANSMISSION OVERHEATING WARNING ON GEN2 HYBRIDS. Transmission warning light is illuminated and vehicle goes into fail-safe mode. The following Check Control messages may be displayed: CC 585 - Hybrid System Fault! CC 569 - Drivetrain, stop carefully! CC 586 - Drivetrain no restart!
