Description
This Mercedes passenger-side SAM module is an original control unit for W211 E-Class and CLS C219 models. Primary OEM number A2115455232 identifies the unit used in these vehicles. It is a key electronic module within the vehicle’s body electrical system, supplied as a used genuine part for correct replacement where the original unit has failed.
The SAM module, or Signal Acquisition and Actuation Module, manages and distributes electrical signals and power to multiple comfort and body functions. It works as a central switching and fuse-related control unit, helping coordinate inputs and outputs for systems such as lighting, convenience electronics and other cabin-side electrical operations.
Common signs of a faulty unit include intermittent electrical faults, inoperative lights or accessories, random warning messages, blown-circuit behavior, communication errors, or moisture-related malfunction. Because this module sits at the heart of several electrical functions, failure can create multiple symptoms that appear unrelated at first.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number A2115455232 before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle configuration 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.
