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.
Harman Kardon Surround Sound System Noise. The customer may complain of a groaning/grinding noise in the area of the rear speakers. Lack of clearance between the tweeter and the mounting contact and/or wires.
