I have a 05 Quattro 3.2 with 225,000 miles and as you probably guessed epc and Trac lights on parking brake seems to work fine the harness going to the throttle body doesn't it have yellow tape on it but black cloth tape on it I have unplugged throttle body a couple times inspecting and cleaning it so don't know if I need to code or what also the battery has been changed and not sure how to do that either any help would be greatly appreciated
