i thought so!!

Hopefully it is just the bulb which has blown and there is not a fault

People normally remove the bulb when there IS a fault.

yep just as i suspected

the bulb was missing hummmm!

the annoying thing is just before i brought the car it went through a MOT so they should of picked this up!!

what do you recon the fault could be? ABS sensor?

check to see if it has all 4 sensors and they are connected

then you need to check which one is broken. You can get a multimeter across the pins on the sensor to check resistance but i dont know the exact value of the top of my head.

From memory they are £80+ to replace.....each.

Should have done yes.
Is normally the sensors but could also be the reluctor ring.

ok thanks

£80 is quite expensive!

does the williams have a diagnostics port to check fault codes?

yes but the abs sensors can be checked independatly

I found the problem

the ABS sensor picks up the input from the teeth on the driveshaft

O/S driveshaft there are no teeth on it
N/S driveshaft half of the teeth have fallen off (due to rust i think)

good going, rings can be had from renault as i have changed mine before.

You might find the sensor has been damaged if the ring has been in contact with it ?

Rings can be had on Ebay.

yeah one sensor had come into contact so that may need changing!

good news the rings can be brought seperately as i thought i was going to have to change the driveshafts
