Description
This rear SAM control module is a genuine Mercedes-benz unit for W221 and C216 models, supplied under OEM number A2215402462. It is an original electronic control module used in the vehicle’s rear body electrical system and power distribution network.
The rear SAM, or Signal Acquisition and Actuation Module, manages and distributes electrical signals and power to multiple rear-end vehicle functions. It works as a central control point for relays, fused circuits, and body electronics, helping coordinate communication and operation of several comfort and convenience systems.
Common signs of a faulty unit include intermittent electrical faults, rear lighting issues, power supply problems, fuse circuit malfunctions, warning messages, or functions in the rear of the vehicle operating unpredictably. In some cases, communication faults or moisture-related internal damage can also lead to irregular system behavior.
This is a used original part, removed from a vehicle and tested before sale. Match OEM number A2215402462 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.
