OEM reference 0025459301, supplier number 5DK007973-20. Genuine used Mercedes-Benz W203 C-Class SAM Control Module — tested and confirmed operational.
The SAM (Signal Acquisition and Actuation Module) is the central power distribution and body control unit for these Mercedes-Benz models. It houses the main fuse matrix and relay array for the vehicle body circuits, managing power distribution and signal routing for exterior lighting (headlights, taillights, fog lights), windscreen wipers and washers, horn, electric windows, and numerous other body and chassis functions. Front and rear SAM variants exist — confirm which is required. The module communicates with the instrument cluster, engine management and comfort systems over the vehicle CAN bus.
Multiple electrical functions failing simultaneously — exterior lighting, wipers or electric windows becoming unresponsive; fuses blowing and re-blowing immediately; fault codes stored under the SAM module address in the body electronics (readable via Star Diagnosis); loss of diagnostic communication with the SAM over the CAN bus; or groups of dashboard warning messages appearing together without a clear single fault.
Good used condition. Always cross-reference BOTH OEM numbers (vehicle OEM and supplier number) with your specific vehicle and build date before ordering — SAM variants differ between model years, body configurations and optional extras. Professional installation is required. The replacement SAM must be configured and coded to the vehicle using Mercedes-Benz Star Diagnosis (XENTRY or SIM/DAS). 14-day returns accepted on unmodified parts.
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.
