BMW service bulletin · NHTSA ID 11029047 · Feb 2026 · also written SI B31 03 26, B310326
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.
Various external influences can cause premature aging of the tension strut hydro-mount elastomer; which can lead to cracks in the material, and leakage.
