Check the wiring to your Speedo sensor, it sits on top of the back of your gearbox.

The sensor is a known problem on the Mk1 focus and is cheap to get a replacement but the removal of the old one can be a sod as it is a tight fit and the retaining pin snaps easily.

If you source your own part i.e. from eBay, make sure you get a pin too.
