Very funny. I tried to update the CAS with winkfp. Failed straight away something about the .opa version. The cas came from an E90, installed it in an X1 same engine (DME/CAS exchange). I thought all 0L15Y cas 3+ have the same program file? FA was already copied from FRM. Also have a strange error. DSC reports it is the wrong one for the car (active steering) Its a DXC89, this error was not there before the swap. Interesting

Not got down to look further. Will have a closer look over the weekend.

Maybe it has a different EWS version. There was a thread when author had 2 identical CAS3, but with different EWS and couldn't programm it.

This may be spot on BUT.... even hardware may be different in a way!! Copied EEprom from the replacement to original CAS. Car does not even come on!! Key locks in though. So got DME ISN written to original CAS and everything back to normal. Very interesting. Original CAS is version 9237047, the E90 CAS was version 914722x. Looks like we cant just mix these things that easily!!!

Hardware musn't match? I think hardware and EWS are two things that must be the same to get donor to work. If it's about ZB, it's better if donor has newer version, but it's not a requirement.

Yes, in my case donor was older so no go. We learn everyday.
