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.
SERVICE ACTION - PROGRAM THE BODY DOMAIN CONTROL (BDC) UNIT: Aftermarket scan tools cannot read fault codes in the Dynamic Stability Control (DSC) unit via the On-Board Diagnostic (OBD) socket.
