I have an Audi A6 and I believe a common fault is warning light cluster malfunction. The ABS warning light comes on when there's nothing wrong with the system. I have spoken with Audi and of course they have denied there is a fault. If I wiggle the connecter to the ABS box it sometimes works for about twenty minutes then back to the warning light coming on again.
I have also contacted the garage where I bought the car as I can see that some work has been done to leads to the connector - they say they never had a problem with the ABS warning light not going out. They would wouldn't they!

Has any one else had this problem and can it be easily fix?

Mine is getting worse.
Pixel problems, gas gauge is unreliable, tach sometimes takes a while to work.

 

Within the past couple days, my engine temp gauge likes to jump by about a notch randomly here and there. Also, the airbag light is on, with no codes returned upon scan, and the outside temp doesn't appear to be working anymore. It seems to sit about 20* higher than actual. It also loves 34* for some reason.

 

My pixels are terrible and my gas gauge doesn't move off full till i have about 100 miles left till empty. From there on its "unreliable" at best.

 

Other than the pixel problem, all other problems can be fixed by www.bba-reman.com for $250. They fixed my tach, fuel gauge, intermittent flickering, and cruise control not working. Apparently there's something in there that allows proper operation of the cruise control too.
