2006 Audi A6 4.2 Quattro ABS / Parking
 

I have an Audi 2006 4.2 Quattro that has the ABS and Parking warning lights on. The bells and whistles keep going off, I'm told they are working properly, but the lights are still on and of course the warning beeps. What sensors drive these lights? I've looked them up and there appears to all kinds of mechanisms for each. It's literally driving me crazy and no one want to look at an "Audi". I hate the dealerships, they don't want to work on an older, they want you to replace it. Anything?

Our dealership works on older cars like this........ I know the abs modules can go out from not servicing the brake fluid normally. May be causing all those lights to come on. I've seen places that re-build them too for a good price. And specific faults stored?

Further to my ABS/Parking and anti-slip lights, I have just heard from my repair guy and he tells me that the module is intact. He further tells me to check the wheel sensors? Can you tell me if these sensors are all different, all the same and or where they are located?
