Mercedes-Benz W221 Door Control Module A2218704993 - Used Original Parts

Diagnosis and Common Symptoms

Failures in the W221 Door Control Unit (TSG) typically manifest as a complete loss of power window function, unresponsive central locking, or failures in side mirror adjustment and folding mechanisms. Drivers often report erratic behavior from seat memory functions or ambient lighting within the door panel. Technicians may observe a lack of communication with the specific door via the STAR/Xentry diagnostic tool, or encounter CAN bus communication faults causing battery drain due to the module failing to enter sleep mode.
