Just before Christmas our Ford Fiesta's speedo started on just below 10mph rather than zero. It moves up and down with the change of speed. I did the gauage test and now it starts at around 30mph instead of zero. I did call our usual garage and he said something about a new dashboard but wanted to get a few more opinions before I commit to taking it in. We have another car so it's not urgent but did want to sell it this year so want it up and running smoothly.
