Product Title

Mercedes-Benz W211 W219 Rear SAM Module A2115450532 - Used Original Parts

Diagnosis and Common Symptoms

A failing Rear Signal Acquisition and Actuation Module (SAM) on the W211 and W219 chassis is a common source of complex electrical faults that can be frustrating to diagnose. The internal relays and logic circuits become compromised over time, often due to moisture intrusion or voltage irregularities. This leads to erratic behavior in all systems managed by this rear control unit.

Key indicators of a faulty Rear SAM include:

• Inoperative or constantly illuminated tail lights, brake lights, or turn signals.
• Erratic fuel gauge readings or a complete failure of the fuel level sensor.
• The remote trunk release failing to operate.
• Intermittent or non-functional central locking system.
• A persistent parasitic battery drain, causing a dead battery after the vehicle sits.

Diagnostic scans will often reveal fault codes related to short circuits, open circuits for various lighting components, or a "No CAN communication with Rear SAM" error.

Each unit is meticulously salvaged from a donor vehicle and undergoes rigorous in-vehicle testing to confirm full functionality of all circuits and relays. This is a reliable, cost-effective alternative to a costly new part, ensuring proper integration without the unpredictability of untested salvage components.
