Description
Original Mercedes driver seat control module for W212 and C207 models, supplied under OEM number A2129005200. This unit manages key electrical seat functions on the driver side and is designed for the seat system used in these Mercedes applications.
It controls and coordinates driver seat movement inputs, seat position logic, and related comfort seat functions within the vehicle’s interior electronics network. As the dedicated seat control unit, it helps the seat respond correctly to switch commands and supports smooth adjustment operation.
Common signs of a faulty unit include inoperative seat adjustment, intermittent movement, memory function faults, lost seat position settings, or a seat that stops responding to switch inputs. Electrical communication errors, uneven operation, or failure of one or more seat functions can also point to a defective control module.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number A2129005200 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and seat memory 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.
