Description
This is a genuine Mercedes-Benz right door control module for the W211 E-Class, identified by OEM number A2118704126. It is an original electronic door unit used in the vehicle’s right-side door system and built to integrate with the car’s factory comfort and body electronics.
Its job is to manage and coordinate door-related electrical functions, typically including communication between switches, locks, window operation and other door-mounted electrical features. As part of the vehicle’s body electronics network, it helps the right door respond correctly to driver and passenger inputs.
Common signs of a faulty unit include inoperative window or locking functions, intermittent response from door switches, communication faults, or loss of electrical operation in the affected door. In some cases, buyers may also notice erratic behavior from related comfort features controlled through the same door electronics.
This is a used original part, removed from a vehicle and tested before sale. Match OEM number A2118704126 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and replacement procedure.
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.
