I am searching for a used one and the common MB part # seems to be A 193 820 00 26 but mine has A 193 820 04 26 on it so I assume they both work. Will find out....
The BCM is for a specific car, it is a computer board that is programmed to do certain functions, I do not think you can take a board from your home computer insert it into your neighbours and have it work from the get go.
A different Mercedes number like you are saying will be different in some way to yours. It may actually harm your car if it does something your car cannot handle.
Can you not get your BCM reprogrammed for some reason?
