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.

JINGLING NOISE HEARD FROM PASSENGER B-PILLAR WHEN DRIVING ON ROUGH ROADS. A "jingling" noise can be heard coming from the area of the passenger B-pillar when driving on rough roads.
