Description
OEM reference 2115457101. Genuine used Mercedes-Benz W211 E-Class SAM Control Module — tested and verified before sale.
The Signal Acquisition and Actuation Module (SAM) serves as the nerve centre for body electrical distribution in these Mercedes-Benz W211 E-Class vehicles. 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.
Diagnostic communication with the SAM being unavailable over the CAN bus when connected to Star Diagnosis; multiple unrelated dashboard warning messages appearing together; fuses failing immediately upon replacement; groups of body electrical functions — lighting, wipers, electric windows — becoming unresponsive; or SAM-related fault codes present in the body control unit.
Good used condition. Always cross-reference the OEM 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). A 14-day return period applies to unmodified, untampered 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.
