I have an ABS fault with the car, 1.8T Quattro sport. When I have scanned it with VCDS it is coming up with "right rear ABS speed sensor short or no signal" which led me to believe it was that causing my problem. I have the ABS light and the big red exclamation mark in computer with the 3 beeps on start up (very annoying as you can't see mpg, outdoor temp etc. I have cleaned and checked reculator ring, and did clean sensor before changing. Today I changed the sensor for a pattern part, don't like using pattern parts, but since Audi wanted £180 for it, I didn't fancy shelling out i cleared the fault before fitting, then changed the sensor. Turned ignition back on after and had the same thing. I cleared the fault again and it came straight back as soon as I turned ignition on. Same fault coming up sensor reading short/no signal. I have checked wire under rear bench, looks all good. Don't think it's module as no fault in relation to that coming up, and apparently has been changed before I bought it. Many ideas? It's doing my head in!!
