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.

AUDIO PLAYBACK NOT POSSIBLE: No audio heard inside the vehicle. Failure of the audio amplifier due to water ingress in the luggage compartment.
