My car is a 325i e90 from 2007, has some problems like the rear pdc not working etc, so I decided to get the protool to inspect all the issues, when I got to vehicle order, both the frm and the cas modules say it’s a 120d e81, I know for a fact that the frm was replaced and probably someone fucjed up the coding and coded the frm data to the cas instead of the opposite, so now I want to ask, how do I fix that? I’ve tried resetting to factory code both modules but they keep saying 120d e81, looking at the general ecu info tho the model is correct, and the vin is also correct. Any help is more than welcome.

Have you tried asking in the Protool Facebook group? You will get a much better idea and responses there.

I think that what you can do is to decode VIN of your car and take FA codes from list that is on the forum. This way you can basically manually put correct FA codes that were used originally in your car.
