Guys,
According to my mechanic, the computer on my car (part #0255455532) is apparently shot. It is not communicating with my vehicle, and has little communication with the diagnostic system my mechanic had. So far, we have only been able to source this part directly from Mercedes for new and remanufactured models. I have been quoted a total repair charge of $1,050 to repair it.
I have also been told that using a used CPU will not work with my car because the CPU's get "married" to the vehicle they are built with. Is that true?

Do I have any other options? What if I sent the CPU to Powerchip or someone else to get it remapped or looked at?
