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.
When starting the vehicle vehicle at standstill, various yellow Check Control Messages CCMs appear. ID code 00042: Brake system. Additional notes: Avoid abrupt braking as far as possible. Drive at a moderate speed. Have it checked by your nearest Service Center. ID code 2046: Braking force assistance.
