Description
This is a rear right door control module for Mercedes W212 E-Class models, supplied as a genuine used original part with OEM number A2129004414. Designed for the rear right door electronics, it is the correct type of unit for vehicles in the W212 E-Class range.
The module manages key electrical functions within the door system, acting as the local control unit for commands and signals related to door equipment. It supports communication between the door components and the vehicle’s wider electrical network, helping systems such as window, mirror, locking and switch functions operate correctly.
Common signs of a faulty unit include inoperative power window or mirror functions, intermittent central locking response on the rear right door, switch commands not being recognized, or communication faults stored in the vehicle system. Electrical irregularities in the door area can also point to a failing control module.
This is a used original part, removed from a vehicle and tested before sale. Match OEM number A2129004414 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.
