+18 2000 Audi A4 Reset Check Engine Light References. Misfire codes, swap coils and plugs, no change. Web i have a little 200 dollar scanner it takes me about 2 minutes to reset that light.

The light will go off on its own once the computer resets. Never pay to get your light reset. Web the most common of all trouble codes is p0420 (it indicates your audi a4’s catalytic converter isn’t scrubbing pollutants efficiently).
