ABS & Traction Control Lights are on :-(
I have a Audi A6 4.2 Quattro auto 1999 and the ABS & Traction control light keeps coming on after a minute of driving.
Once the engine is turned off it resets and turns itself off then comes back on the next time round. Has the Diagnositics on it and its an ABS sensor fault. But they all look ok.
I've heard the rear brake light switch can make this happen, or the abs/tc unit needs to be cleaned.
So just want to know if i'm barking up the right tree or not. If so, how do you clean that unit and where is the brake light switch located to?
If i'm wrong then slap me and let know how :-)
