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.
TELEMATICS UNIT DEACTIVATION DUE TO 3G CELLULAR TECHNOLOGY DISCONTINUATION: The discontinuation of 3G cellular communication for Combox, TCB 3G and ATM 3G (Telematics ControlModule) can no longer be supported by the cellular network provider starting February 2022.
