Hello everyone,
I Had an issue with a fuel pump relay J17 and i went under the dashboard and swapped the relays which looked the same. I also replaced a 395 relay with a spare i had. I tried to start the car , it cranked for a split second and stopped. I suspected it was the battery but it wasnt.
Scanned with vcds and i have a code 00002 - Transmission control unit 004 No signal/communucation - intermittent. The car wont crank.
I dont know where the TCU is as to check the connection. Also is there anything i should check.
A3 8P 2006 2.0 TFSI DSG
Thank you
