Yes, it is. Your staring down a deep, dark rabbit hole. The car will not start with the used CAS module because the ISN stored in the DME doesn't match.

The easiest solution if you need to install a used CAS is to find a local shop with the AutoHex II scan tool. They will be able to read the ISN from your DME and write it to the used CAS module.
