BMW service bulletin · NHTSA ID 10250371 · Feb 2024 · also written SI B51 17 23, B511723
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.
While driving at highway speeds, wind noise can be heard from the exterior mirror assembly. In some cases, this can be also felt in the B-pillar area.
