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.

WIND NOISE FROM WINDSHIELD SIDE TRIM: A wind noise from the windshield area is present while driving caused by a separation of the windshield side trim (circled) on one or both sides. Improper bonding of the side windshield trim during production.
