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.
FALSE ALARM ACTIVATION TRIGGERED BY INTERIOR ULTRASOUND SENSOR: The DWA (anti-theft alarm) triggers for no apparent reason with all the vehicle's doors and windows closed.
