Default 2000 s4 no communication with ecu

I don't know if this will help but I have a 2000 A6 2.7T and on my car I could not communicate with the ecu either. I discovered it was a bad ABS module, if I unplugged it I could communicate with the ecu just fine.

Does anyone know if the immobilizer could cause the problem?
