Ok, so i have found the Solanoid valve relay...shame replacing it did not fix the fault!
Anyway, took some photos to explain where it is and how to change it.
Also a picture of the ABS computer and the LED which flashes to indicate which fault it has.
First picture showing the ABS Relay in engine bay:
I found the overhanging bulkhead prevented me from lifting up the plastic cover so its easiest to unbolt the whole lot and move it out.
This picture shows the unit with the plastic cover removed.You only need to push the two small clips out to take it off. Then the Relays just pull out.
Last two pictures show location of the ABS computer. It looks abit odd because i have moved the carpet etc. Basically you need to open the passenger side door and kneel down.You should see a plastic trim/cover between the carpet and the (near) glovebox.It will have a clip or the flare attached to it.
Its not necessary to take it all off to see the LED. Just lift the door rubber a bit and push the trim over until you can see it.
Heres what the computer looks like in case you're interested!!
Hopefully this will help someone else, and its not too basic?
