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.
REWORK SEAT MECHANISM 2ND ROW SEAT: The mounting nuts on the rear left seat frame (60% seat, situated behind the driver's seat) were not properly tightened.
