I have my 00 a6 2.7tautomatic, i have a problem scanning my car, when i plug in the VAG scanner it will give an "link error", but also when i turn the key into accesory the CEL isnt on, only seat belt light is on, epc, and battery, it doesnt look right to me. i had a 2000 a6 before and that one was showing right things, PLEASE HELP, car wont go through inspection without the scanner connectiong to OBDII. so i was wondering does my ECU have to do anything with this???
