Description
OEM part numbers 2115455301 and 5DK008047-27. Mercedes-Benz W203 SAM (Signal Acquisition Module) body control unit — genuine used, tested original equipment.
The SAM (Signal Acquisition and Actuation Module) is the central body control unit for these Mercedes-Benz models. It functions as the main fuse and relay board for the vehicle body circuits — managing signal routing and power distribution for exterior lighting, windscreen wipers, horn, electric windows and numerous other chassis and comfort functions. The SAM communicates with the instrument cluster, engine ECU and body control systems over the CAN bus and protects circuits via integrated fuses and relays.
Multiple body electrical functions failing together — exterior lights, wipers or windows unresponsive, fuses blowing repeatedly, fault codes stored under the SAM address in the body electronics, diagnostic communication failure with the SAM, or clusters of dashboard warning lamps appearing simultaneously.
Good used condition. Always verify both OEM part numbers against your exact vehicle and build date — SAM variants differ between model years and option packages. Professional installation with Star Diagnosis (SIM/DAS or XENTRY) coding is required to match the module to the vehicle. 14-day returns 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.
