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.
When driving over an uneven road surface, a “thumping” noise can be heard from the front axle. Seeattached video V 31 01 26. Under certain weather conditions, a “groaning” noise may be heard during steering movements
