Description
This rear fuse box SAM module is a genuine Mercedes unit for the W221 S-Class, supplied under OEM number A2215403050. It is the rear signal acquisition and actuation module with integrated fuse and power distribution functions used in the vehicle’s rear electrical system.
In operation, the rear SAM manages power distribution, fused circuits and signal control for multiple rear-body electrical consumers. It works as a central control point for monitoring, switching and protecting various electrical functions while supporting stable communication between connected systems.
Common signs of a faulty unit include intermittent electrical faults, loss of power to rear vehicle systems, blown fuse issues, communication errors, or functions that stop working without a clear wiring fault. Electrical irregularities in trunk-area, rear comfort or body-related circuits can also point to a failing SAM module.
This is a used original part removed from a vehicle and tested before sale. Match OEM number A2215403050 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.
