Description
This Mercedes-Benz seat heating control module is fitted for W211 and W219 models and is identified by OEM number A2118203626. It is an original electronic control unit used within the seat heating system to manage heated seat operation and maintain proper response from the seat heater controls.
Its job is to regulate the seat heating function by processing switch inputs and controlling power delivery to the seat heating elements. In normal operation, it helps the system warm the seat evenly and supports stable, consistent heat output as part of the vehicle’s interior comfort system.
Common signs of a faulty unit include heated seats that do not switch on, heat that cuts in and out, uneven seat warming, or a seat heater that stops responding to the dashboard or console controls. Intermittent operation and stored seat heating faults can also point to a failed module.
This is a used original part, removed from a vehicle and tested before sale. Please match OEM number A2118203626 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and system configuration.
