[size="4"][/size][b][/b]Hi, there

i have a 51 plate ford focus, when driving the mph gauge drops and stops working all together, as this happens the rev counter stay's normal but u feel a slight drop in power. If you put the car in neutral it will stall when applying the break, then if you put it into gear while rolling it will kick in again but still the mph gauge will not work wired?. All of a sudden it will work again and you feel a boots ? this could happen more than one time on a journey. any help would be a great.

Thanks Jamie ..

either the VSS (vehicle speed sensor) or the dreaded instrument cluster. i think a genuine vss is about £30-£40

I had this happen and both the VSS and cluster were replaced under warranty but that still didn't fix it. In the end it turned out the harness to the VSS was chafed through where it runs close to the gear linkage so it's worth getting the dealer to check that.
