Wow .. that's a load of replys , it all sounded quite possible , to answer the questions
No not had the wheel off , no cant turn ABS on I only have a button for traction control , I have been pressing it to turn traction control off .... and turning it back on as it goes way too quickly round bends for the poor little 16" wheels ! before this happened the traction control was cutting in way to early on right hand bends , I had thought it was after a 4 wheel alignment 12 months ago but not sure ...I have a feeling this was the steering angle sensor ..hope its not the abs controller as that sounds expensive !! as the brake lights work I guess its not the brake switch, anyone in the west midlands with vagcom able to run a scan for me , my MAC wont run vagcom ;o(
