SIB 84 02 26: Telematics unit failure
Telematics unit failure on BMW G01/G02/G05/G06 and other models (2020); BMW repairs affected cars free under a service campaign.
BMW service campaign · NHTSA ID 11035408 · Jul 2026 · also written SI B84 02 26, B840226
What it covers
A service campaign is a fix BMW performs free on affected cars. Ask a BMW center whether it is open on your VIN.
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.
