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.
EXCESS NOISE WHEN DEFROST BLOWER IS AT MAX. Loud, rushing, wind noise is heard from ventilation outlets when defroster blower is set at maximum speed. Software error in IHKA (Automatic Climate Control) module. Ventilation duct noise.
