BMW service bulletin · NHTSA ID 11027761 · Jan 2026 · also written SI B31 01 22, B310122
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.
During inspection and/or diagnosis there is noticeable dirt/grease buildup on the axles near the inner and/orouter CV boots.
