BMW service bulletin · NHTSA ID 11036557 · Aug 2026 · also written SI B64 08 26, B640826
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.
Customers may hear a noise from underneath the vehicle, or feel something rubbing being transmitted intothe body of the vehicle while driving. Customers may find water inside the vehicle on the front carpet.
