Description
This Mercedes-Benz SAM control module is a genuine OEM body electrical component for the W211 E-Class and S211 estate. Primary OEM number A2115450532. It is designed to read switch and sensor inputs and distribute power and signals on the front passenger side of the car, so the electrical system can operate accurately and reliably. As an original Mercedes-Benz unit it keeps the correct fit, connector layout, and factory communication behavior.
Its job is to switch and control the body circuits on its side of the vehicle, including exterior and interior lighting, turn signals, wiper and washer functions, and various comfort outputs. It communicates with the central gateway and the other modules over the CAN network, helping the car coordinate lighting, signaling, and convenience functions with fast, correct response, and keeping the wider electrical system stable.
Common signs of a faulty unit include lights, indicators, or wipers that do not work or that flicker, warning messages in the instrument cluster, random electrical faults that are hard to trace, stored fault codes against the module, or several unrelated functions failing at once. Water ingress is a frequent cause, and when the module becomes intermittent the faults often come and go as the internal board or connectors degrade.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number A2115450532 before ordering. Professional installation is recommended, and coding, programming, or adaptation may be required where applicable for the specific vehicle system.
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.
