Official summary
Once the Telematics Module (TCB2) enters sleep mode, a BMW Data Services trigger for Remote Services(remote engine start, lock/unlock/climate conditioning) will not be able to reactivate the TCB2. Due to this issue, Remote Services will not function in the vehicle when parked and locked.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
