A0285459832 Mercedes-Benz W220 SAM Control Module 05045113 – OEM Used & Tested

Description

OEM reference A0285459832, Bosch supplier number 05045113. Genuine used Mercedes-Benz W220 SAM Control Module — removed from a tested, running vehicle.

Serving as the body electronics’ primary power distribution and control module, the SAM (Signal Acquisition and Actuation Module) underpins every major body circuit in 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.

Windscreen wipers or washers ceasing to operate; headlights, taillights or other exterior lights failing with no obvious single bulb or relay cause; fuses that re-blow on replacement; fault codes stored under the SAM unit address via Star Diagnosis scanning; or loss of CAN bus communication between the SAM and the vehicle’s other control units.

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). Unmodified parts may be returned within 14 days of receipt.
