I had B6 a4 and remember that when the headlights and fogs were on the lights letup on both the knob and the dash in front. I have a b7 now and no lights show on the dash displaywhen the headlights or fogs are on. I brought itback to dealer to check as I had a cd plAyer issue and they said the newer model does not show those lights?!!! So anyone have them showing in a b7 anyone not or anyone have stereo issues that could affect these electrics. I just don't believe that it would be the case!
