My better halfs Fiesta Zetec S on a 51 plate has had a couple of warning lights come on the dash. The ABS and traction control light have come on, at first intermitently but now stay on all the time. I have no experience at all with abs system so any help is much apreciated.

 

Normally either a dirty sensor, or a knackered one. Can be cleaned if you take them out. Be very careful though, they're very sensitive and fragile! Stick it on a diag machine to find out which one is playing up.
