Morning folks, so I came to start the car the other day a few days after having a few tyres put on and tracking done, and I got two faults one after the other come through on the dash, the first was ESP/ABS fault an then Headlight range finder defective. My first thought was maybe the battery's low so I charged it over night, an never got the faults again till later that day, I know this doesn't rule the battery out but thought it was worth a try, so I did some digging online an it seems the ABS sensors can throw these 2 faults, so I was just curious if anybody else had this happen before? 

I wonder if the wiring was damaged by an over zealous mechanic when the tracking was adjusted.

Hmm the thought has crossed my mind, I know the lad quite well up there so I think I'm going to take it up there an see what he says about it.. not sure what wiring you'd actually be near while truing up the tracking to be honest. 

The wheel sensor wiring is close to the track rod ends.

Alright folks, got to the bottom of the fault lights coming on ABS ESP & Headlight range finder, it was all tied to the rear right abs sensor!
