So im trying to check my cel light with a scanner and it wont cumminicate. Ive read if your abs light is on that can interfere with it. My abs light is on, and I have an aftermarket radio. Im trying to unplug the abs module to see if the scanner will work, how do I go about it without tearing stuff up lol
The car is a 99 a6 Quattro 2.8....thanks for suggestions.

 

Im wondering if im asking this in the right spot...anyone?
