Hey guys.
Changed my rear swing arm recently and when put back together the bl***y ABS light came on after driving for 30 seconds!!!

Now failed MOT because of abs warning light !!!

Does anyone know how to change the sensor coz it won't budge !!??
and wheres best place to get them? ......think I was quoted about £80 a while back?? which sounds excessive to me for a piece of plastic on a string?

Cheeers guys
