2001 Audi A4 2.8 Check Engine light came on. Used scanner and received "No Link". Any suggestions why this happened?
the scanner you userd is probably not got the software it requires for the audi. Only certain name brands are capable of reading audi codes. try taking it to the audi dealer and have them scan it it costs a few bucks but they should be able to pin the problem down alot easier then an obd tester can.
