✅ Genuine OEM Rear Signal Controller: Authentic factory Mercedes-Benz rear signal acquisition and actuation module. This unit acts as the primary computer and power distribution block for the back half of the vehicle. It is a direct fix for vehicles suffering from common W211 rear SAM failures such as:
Non-functional trunk release latches or soft-close trunk failure
Fuel gauge reading "empty" despite having gas (loss of fuel level sender signal processing)
Inoperative rear tail lights, brake lights, or turn signals
Central locking system remote key fob range issues (loss of power to antenna module)
Non-functional rear window defroster or power headrests
✅ Fully Tested Electronic Channels: Professionally pulled, detailed, and bench-tested:
Circuit Rails & Relays: All fuse terminals and high-amperage relay sockets maintain clean, tight contact tension with zero internal resistance.
Micro-Controller Communication: Clean diagnostic handshake confirmed. Scanned with Mercedes diagnostic systems to ensure zero internal hardware errors or CAN bus network communication drops.
✅ Zero Water Damage: The primary cause of failure for the rear SAM is trunk seal leaks dripping water directly onto the module located in the left side cargo compartment. This unit has been meticulously inspected — the internal circuit board and all wire harness plug terminals are completely dry, shiny, and free of green corrosion or burnt traces.
⚠️ PROGRAMMING ADVICE: While this rear SAM is physically plug-and-play and will restore basic power flow, it contains vehicle-specific coding options (such as Sedan vs. Wagon lighting configurations, power rear sunshade options, or anti-theft alarm settings). Depending on your vehicle's exact trim and options, you may need a technician with a Mercedes STAR diagnostic scanner to transfer your original SAM’s coding or toggle your specific vehicle configuration settings to prevent dashboard warning lights.
✅ Safe Shipping: Packaged inside an anti-static safety bag and wrapped with heavy-duty bubble padding in a sturdy box to ensure all external fuse prongs, plastic housings, and lock clips remain flawless during shipping.
