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.
SEAT HEATING NOT ACTIVATED WHEN ENGINE IS STARTED USING REMOTE STARTING SYSTEM: When preheating/precooling the vehicle via the remote starting system (Remote Engine Start), the seat heating on the driver's side is not activated.
