SIB 66 06 20: Electrical system warning message

Electrical system warning message on BMW G01/G02/G05/G07 and other models (2018–2022); BMW gives an inspection and repair procedure.

BMW service bulletin · NHTSA ID 10214991 · May 2022 · also written SI B66 06 20, B660620

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.

The functionality of the right front SRR sensor could be reduced which would display the "Driving Assistance" Check Control Message.
