possible, but unsoldering and resoldering the AM29F400 is pretty hard stuff.

I am not a very rich e46 owner
but you have to be in this case. the needed software is ~5000$ and you will search several years for keys and cracks, if they exist at all.

do yourself a favor and search for an unused dme, they are out there and most of the time pretty cheap, much cheaper then virginizing a used one.
