Description
This is a genuine Mercedes left door control module for the W211 E-Class, supplied under primary OEM number A2118701126. Designed as an original electronic door unit for the left side, it is used in Mercedes W211 E-Class applications and fits where this exact part number is required.
The module manages key electrical functions within the door system, coordinating signals between the door components and the vehicle’s body electronics. It typically supports operation of door-related features such as window, mirror, locking and convenience functions, helping the left door systems respond correctly and communicate with the rest of the car.
Common signs of a faulty unit include intermittent or non-working window operation, mirror adjustment faults, central locking problems on the affected door, loss of switch response, or communication errors stored in the vehicle electronics. Electrical issues in one door that appear suddenly or remain isolated to the left side can also point to a failing module.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 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.
