Are all the crossfire BCMs the same i.e. UK and US specs. Cant get one from the UK for a reasonable price but there seems to be a few about in the states, if they will fit a UK car?
The body controll unit is in the box next to the ECU. I believe it is the module closest to the fender. Please carefully pull it up so that you can write down the Mercedes part number. The MB number starts with an "A" I can check and verify if it is the same as the USA cars. One thing I worry about is coding the car. It may contain the VIN number which could make things rough on you. You may also want to check with Mercedes and see if you can order the part number on your module. I have found MB to sometimes be cheaper than Chrysler. I will be at an independant MB shop today working on my car and will ask the tech about replacing body control units.
There is also a step by step procedure for checking the body control unit and you may want to run through that to ensure it was diagnosed correctly.
