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.
INCREASED EFFORT REQUIRED TO OPEN DOORS: One or more doors may require increased effort to open.
