the ABS light came on yesterday driving to work, stayed on until i parked up and left it for a bit, then on restarting it stayed on until i pulled away then it went out

light stayed out until going to work this morning and same thing again with the light staying on/going out.

i've figured out it's a fast sweeping left hand slip road that sets it off, but either way i'm guessing there's a sensor fault?

i can't get to the garage until next friday but so i can work out roughly how much this will cost, has anyone had a test and sensor change recently and how much was it?

cheers,
Paul

 

anyone?
