I'll see if I can disconnect it and see if anything changes. Then if nothing changes I'll recheck when I hopefully get the car running and see what voltage its kicking out.

Hi all, I've done something very daft and put 24v on my S3 8P... My car was dead so I borrowed my friends jump pack which I didn't realise had 24v on it. I've managed figure out a few things that got fried with was the BCM Module, Steering Control Module and potentially the ECU. I have now replaced all of these with second hand ones but I still have Fuse 38 blowing when I turn the ignition on. The car starts for about 2 seconds then cuts off (I'm guessing this is the immobiliser) then it will just crank and not start. The dash has no lights on and i cannot connect to the car via the OBD port. I've not had these modules coded to the car yet as I wanted to get it to a state where there's no fuses blowing before getting someone out who can code as they charge a call out fee so I was hoping to do it all on one day. So I'm hoping someone has done this before or have a rough idea where to look now as I'm now completely out of ideas. Any help would me greatly appreciated! Thanks in advance.
