BMW service bulletin · NHTSA ID 11034466 · Jun 2026 · also written SI B65 12 26, B651226
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 voice command to deactivate Automatic Engine Start/Stop function can also trigger the activation ofIconic Sounds.
