CHECK ENGIN LIGHT ON on 2002 Audi TT Quattro
Asked by for the 2002 Audi TT Quattro
Tomi, Do not know exactly what the code means, but I have a 2008 TT and got a couple check engine lights in my 60,000 miles... When that light comes on, it is a good warning to get it checked by a certified mechanic or your local Audi dealership service department. My last check engine light had to do with a faulty diverter valve rupture, thereby, not giving me turbo boost. I have had three Audis in the last 8 or so years and just know this is a sign that can mean many things, and it is better to not drive the car and get it fixed ASAP. Tell me how it goes.
