Without any doubt, the VSS (Vehicle Speed Sensor) has failed. This is
causing both faults. It is *very* common on early cars.
Bottom line - 100UKP for a garage to replace it, or 25UKP and a fairly
tricky 45minute DIY job.
The replacement will be a modified one, to stop it happening again.
If you decide to have a go, there is plenty of archived info in this group
to help. Google here for VSS. Note that the retaining pin generally gets
mangled during removal so make sure to get one as well. Helpfully, dealers
don't normally keep them in stock!
Post again if you need further help.
