1998 A6 2.8 OBD No Connection Please Help
Hi, I have been trying to get my car to pass CA smog and every place I have taken it to says their smog machine wont hook up to my computer. I bought the special audi obd scanner and it wont work it just says scanning and doesnt do anything I waited over an hour tonight. The check engine light isn't on or anything. Please help with what may be wrong. I know it has power because the scanner powers up through it. Thanks for all your help
