I have an Audi S4 B8 3.0 TFSI – A few months ago developed a problem with the sports differential and I have been trying to resolve this for a few months now. Just wondering if anyone on here can point me in the right direction, as I am now at a loss.
I was driving along and on the dash appeared "sports differential fault" when I got back, I did a VCDS scan which returned:

I replaced the module with another controller from eBay (same codes and looked identical) which gave a different error code.

I have had an auto electrician have a go at programming this to change the VIN on the module, but it comes back with the same errors.
Does anyone know where I can go next with this? As every time I start the car it beeps “sports differential fault” which is a constant reminder to fix it.
Cheers
