[cookie boy]

Hello can anyone tell me, why does my abs light comes on at high speed but if i stop the car an pull the key out, its allright again until i get back up 2 speed, ive checked that the abs isnt working bye jumping on the brakes when the light is on, and when its off they work fine. Ive got 18inche alloy wheels on it could this be the problem or is at sensor or something, please help cheers cookie boy

First thing to do is check the ABS wires have not got trapped or are corroded. If that is ok then you will most likely need to rig it up to VAG-COM diagnostic software.
