A copy of the fault scans would be helpfull if you've got them?

You'll probably need to replace one of your rear wheel speed sensors. Did one today on mine and all sorted now.

yea i agree most likely to be a sensor, You can use VAG COM measuring blocks to see which 1 it is, I have loads of Diagnostic equipment for VW/AUDI/SEAT/SKODA, inc key programming starting from 17.99-104.99 all of them will be able to tell you which one to replace, sometimes after replacing you will need ABS light reset, my tools can also reset all lights, contact if you are interested, Cheers
