BMW E60 (528Xi) – The car presented with an intermittent turn signal and brake light, warnings being received on the dash mounted iDrive system. Examination by our BMW Service techs quickly reveled that the fault was the rear rear circuit board, and wiring harness for the passenger side.
You will note that the ground lead wire and electrical connector have melted into the plastic wiring plug, damaging both the wire, the connector, and the taillight circuit board. BMW has had an issue with this on the E60, and on other BMW models, and has developed an improved wiring harness and circuit board to correct the fault.
In this case the repair consisted of cutting off the damaged connector and plastic plug, and preparing the wires to accept new connectors. These new connectors were then installed into the new plastic plug. The circuitboard for the taillight was replaced with an updated part, and all of the light bulbs changed at the same time.
