Mercedes SAM / BCM / Fusebox Services
The SAM (Signal Acquisition Module) is the Mercedes body control / fusebox unit — Front SAM handles front lighting, wipers, and engine bay loads; Rear SAM handles tail lights, trunk, and rear comfort loads. When a SAM fails, a 1:1 clone onto a compatible donor SAM lets the car run again without a dealer SCN coding trip in most cases. BCM, fusebox, and SAM clone work is all bench-level chip-to-chip work.

Not Sure Which Service to Choose?
If you are unsure which option matches your Mercedes module, the safest path is to email or text us photos before ordering: full label of the original module (the one you want serviced), full label of the donor module if you already have one, the part number, hardware revision, and software/calibration sticker, and a photo of the connector pinout if visible. We will confirm whether the service is supported for your specific part number and hardware revision before you order and ship.
Compatibility Warning
SAM and BCM cloning requires a donor of the same part number prefix and same hardware revision. Front SAM and Rear SAM are different modules and cannot be cross-cloned. Send us photos of the module labels before purchasing a donor.
What to Ship

FAQ
What does the SAM clone preserve? VIN, SCN coding, personalization, adaptation values for lighting, comfort, and load shedding, and component protection data when applicable.
Do I need both Front and Rear SAM cloned? Only the one that failed. Front and Rear SAMs are independent and only need the failed unit serviced.
Will the car still start after a SAM clone? Yes — the clone preserves the immobilizer-side communication. The car should start and operate normally with the cloned donor in place.
