Use this Mercedes ECM order form to provide us with the year and model of your Mercedes. Once the form has been submitted we will respond by phone or email to go over pricing and availability. We offer a very large selection of Mercedes computers: ECU / ECM and TCM transmission control units for all models. All of our auto computers come flash programmed and SCN coded to accept your VIN number and Mercedes benz ignition key. When you receive your new control unit it will be plug and play unless you order a blank control unit. No expensive tools or dealer trips will be necessary if we do the programming. Call us if you have any questions. If you are certain that we will be doing all of the programming then go ahead and ship your bad ECU to the address below since we will require your ECU in order to read all of the vehicle specs and security settings. Also this is an exchange service so we keep all damaged cores.
