Description
This Mercedes rear SAM fuse box module is an original electronic control unit for the W211 E-Class, supplied under OEM number A2115453301. It is the rear Signal Acquisition Module assembly that combines fuse box and control functions in one housing for the rear electrical system.
In the vehicle, the rear SAM distributes power, manages fused circuits and switches selected rear body functions through internal electronics and relays. It works as a central rear electrical controller, helping coordinate systems such as rear lighting and other boot-area or body electrical functions.
Common signs of a faulty unit include intermittent or complete loss of rear electrical functions, lighting faults, blown fuses without a clear cause, water-related corrosion issues, or communication faults stored in the vehicle diagnostic system. Multiple unrelated electrical problems in the rear of the car can also point to this module.
This is a used original part, removed from a vehicle and tested before sale. Please match A2115453301 exactly before ordering. Professional installation is recommended, and coding, programming or adaptation may be required depending on vehicle equipment and 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.
