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.
SERVICE ACTION - INSTALL GROUND STRAP / SUPPRESSOR BELT: Corrosion developing on the rear suspension contact points can lead to poor radio reception over a certain duration of time.
