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.
After performing vehicle test, fault code 80422D "self-leveling suspension missing slave" will not clear.
