Mercedes-Benz W205 Rear SAM Control Module | C-Class Boot Fuse Box Spares

Description

Restore seamless electrical power distribution and resolve frustrating network communication glitches in your luxury vehicle with this premium Mercedes-Benz W205 Rear SAM Control Module (Signal Acquisition and Actuation Module / Boot Fuse Box Assembly). Specifically sourced and verified for the W205 C-Class platform (produced from 2014 to 2021), this intelligent factory electronics unit is the definitive replacement for vehicles experiencing erratic rear lighting behavior, non-responsive fuel level sensors, central locking failures, or electric boot lid malfunctions.

The Rear SAM Module serves as the primary localized computer gateway and heavy-duty fuse relay junction for the entire rear half of your C-Class. Tucked neatly behind the right-hand trunk liner trim panel, this module communicates continuously over the high-speed $CAN-bus$ network to process commands for vital systems. It directly regulates your LED tail lights, brake lights, indicator clusters, electronic fuel pump delivery system, rear window demisters, electric blind operations, and the pneumatic or electric boot latch mechanisms.

Because of its location within the trunk cavity, the Rear SAM unit is highly susceptible to severe moisture damage. If the vehicle’s rear window rubber seals fail, or if the boot lid drain channels become clogged with debris, rainwater runs straight down the inner structural pillaring and leaks directly onto the SAM module housing. This moisture causes rapid, hidden green oxidation across the multi-layered internal printed circuit board ($PCB$). The resulting short-circuits lead to chaotic electrical behavior—such as your battery draining flat overnight, tail lights remaining illuminated permanently, or a fuel gauge that suddenly drops to zero despite a full tank. Swapping out a water-damaged unit with this verified, corrosion-free assembly instantly brings your car’s complex network back to stable parameters.

Manufactured with heat-resistant composite insulation shells and high-conductivity terminal pins, this assembly comes complete with its original, unburnt factory fuse arrays and heavy-duty system relays. Trust TP German Auto Spares for fully verified, diagnostic-tested Mercedes-Benz electrical brains, SAM control modules, and trunk fuse junctions that keep your C-Class running smoothly on South African roads.
