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.

Service Action: Wiring Harness Sensor Rear Module. The wiring harness for the sensor of the rear convertible top module can be routed incorrectly, which can cause damage to the wiring harness.
