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.
The driver’s seat heater doesn’t work after the installation of a replacement seat harness part number (P/N)52 10 7 414 701.
