The Sam unit in these Smart cars is not just a fuse box but the central control unit for all the cars electrical systems. When these units fail it can be a very costly repair. Usually your only solution is to take your car to Mercedes and get them to supply and fit a new Sam unit, they then perform all the relevant coding to it to make it work. We can repair / refurbish Sam units and offer a replacement service at a fraction of the cost of a new unit.
Sam faults are normally due to the ingress of water into the electronics, a common fault on roadsters. To start with the SAM will usually only partially fail. Maybe your hazard lights, heater or electric windows will become intermittent or stop working completely. if you act quickly at the first signs of failure a repair is usually possible.
Where possible we offer a SAM cloning service.
If you can’t get your car to us you can post us your old SAM with a donour.
The SAM unit works in conjunction with your ECU, dash & keys. They are all married together so to repair this yourself you will need to replace all of these items. We have matched sets of used SAM, ECU, Dash and Key transmitters kits in stock should you require one. We can even match the mileage to your car.
Service 1: Cloned Exchange SAM
When I receive your Faulty SAM Unit, I will clone the data onto the Exchange SAM Unit. The now Cloned Exchange SAM Unit will be returned to you by tracked delivery.
On your receipt of the Cloned Exchange SAM Unit, all you need to do is just fit it to the car as it is ready to use, just plug and play. The VIN number, mileage and keys code and options etc have been copied across so no further coding is needed with a MB Star. Vehicle may need to be driven couple of hundred kms before it syncs up with the rest of the modules.
PLEASE NOTE: The Faulty SAM Unit will be retained to be used as spare parts for any repairs. As this is an exchange service.
