Mercedes Door Control module Programming

Mercedes ECU programming using Mercedes Star and Mercedes Xentry diagnostics. This mercedes SLK came into us with intermittent door locking issues after the door lock mechanism was replaced by another local garage. After running diagnostics on the left hand door control module we found no faults, the car was fully satisfied that everything was in full working order and functioning correctly.

This was not the case as more often than not the door would fail to lock, So we put our auto electrical expertise to the test and started to remove the door control module behind the door. Once we has removed the door control module we found it to be damp and full of moisture. Once removed from the vehicle we opened the unit up to find corrosion and a damaged PCB.

On behalf of the customer we sourced an exact match door control unit for the vehicle and coded, after spending a few hours in the workshop the fault is nowhere to be seen and all function are fully operational.

As Mercedes diagnostic specialists we can diagnose and repair electrical faults using specialist equipment and expertise. Our workshop is based in Saxmundham, Suffolk but provide a mobile service for diagnostic testing in Suffolk, Essex and Norfolk.
