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.

FUEL FILLER DOOR STICKING: The fuel filler door may be sticking requiring multiple attempts to open. The fuel filler door material can swell in wet conditions causing the filler door to stick.
