How can my car still tell is there another unit that's coded to the car?

I cant answer that for sure, I know it seem illogical as you are ultimately replacing thew whole "nervous system" but still - take all additional components that are visible&communicative trough VIDA - most of them require car-coding, like radio, BCM or even steering control unit. Some of those carry VIN+parameters information, when you swap critical parts like CEM and ECU from donor, those parts are trying to communicate to rest of the car but doesnt find matching components, maybe thats why such frankenstein wont work. Bear in mind, P1 is very complicated as for its age and almost every component is somehow comunicating to CEM. Also, most usual answer for a questions on swapping parts is "it has to be coded in dealership", hence all the issues I guess.
