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.

Horn(s) Fail to Work. While trying to activate the horn, one or both horns fail to work. One or more of the following fault codes can be stored in the FEM: ? ""8044A3 - Wiring, horn short circuit to earth"" ? ""8044A4 - Wiring, horn short circuit to positive"" ?
