Description
This is a used original Mercedes left door control module for the W211 E-Class, supplied under primary OEM number A2118200326. Designed for the left door system, it is the electronic unit that manages key door functions within the vehicle and communicates with related comfort and body systems.
In operation, this module helps control functions such as the power window, mirror-related commands, central locking responses and door-based electrical features. It acts as a dedicated controller for the left door, receiving switch inputs and sending commands so the door equipment works smoothly and in sync with the rest of the car.
Common signs of a faulty unit include inoperative or intermittent window movement, mirror functions that stop responding, central locking issues on the affected door, or loss of communication with the door electronics. Electrical faults, water ingress, internal circuit failure or connector damage can all lead to erratic door behavior.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number A2118200326 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and system setup.
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.
