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.

INTERMITTENT DISTORTION IN AUDIO SYSTEM, DRIVER'S SIDE. Distortion in audio system from subwoofer on driver's side. Rodent ingress into subwoofer enclosure.
