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.
ROOF TRIM STRIP LOOSE AT REAR: The roof trim strip may be loose at the last (rearmost) clip as shown. This can occur on either side of the roof, or on both sides.
