A0345456532 Mercedes-Benz W220 SAM Control Module 05045140 – OEM Used & Tested

Descrizione

OEM reference A0345456532, Bosch supplier number 05045140. Genuine used Mercedes-Benz W220 S-Class SAM Control Module — tested and confirmed operational before despatch.

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 Bosch/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.
