Description
This is a genuine Mercedes left door control module for the W211 E-Class, supplied under OEM number A2118201526. It is an original electronic door module designed for the vehicle platform named in this application and built to integrate with the car’s factory comfort and door systems.
The door control module manages key electrical functions within the left door, including communication between switches, window operation, central locking signals, mirror-related commands, and other door-mounted electrical features. It acts as the local control unit for the door, helping the vehicle’s comfort system respond accurately to driver or passenger inputs.
Common signs of a faulty unit include inoperative window functions, intermittent central locking issues, mirror functions not responding correctly, or loss of communication with the door electronics. Electrical faults in this type of module can also cause inconsistent door behavior or stored fault codes during diagnostic checks.
This is a used original part, removed from a vehicle and tested before sale. Please match OEM number A2118201526 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and system configuration.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
