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.
WHISTLE NOISE FROM FRONT DOORS WHILE DRIVING: There is a whistling noise present from either front door while driving at speeds of 60 mph. This can occur on one or both front doors.
