Golf VR6 Mk3 ABS light problem

Hello People,



Was wondering if someone could help me out. My P'reg Mk3 Golf VR6 is having
ABS problems.



The ABS fault light stays on the dashboard all the time. There are no faults
registering on the dashboard display, just the light. Anyone got any ideas
what to try?



I've heard it might be the ABS sensor in one of the wheels, does anyone know
how to work out which one or how difficult it is to replace?



Also, if this is something that requires a garage, can anyone recommend
someone in the Slough or Berkshire area other than the vw dealer.



Thanks in advance for any advice,



John
