I have an 02 Audi a4 3.0 and the check engine light came on again as usual... But now when I plug my code scanner in it won't connect . I took it to autozone they tried theirs same thing then I tried one of those solaris ones from buddy at snap on still nothing . I don't know what could keep it from connecting. There is power there because when i plug the scanner into the port the scanner come on but it won't connect to get the codes same thing with all of the scanners



any help? thanks
