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.

NOISE DURING FORWARD / BACK SEAT ADJUSTMENT OVER THE ENTIRE LENGTH OF TRAVEL: A loud screeching noise can be heard from the front driver's or passenger's seat during forward/back seat adjustment.
