Damo,
Misunderstood your post. If you're talking about your coolant temp then you have a duff temp sender or a sticky thermostat.
It might be initial signs of a poorly thermostat...they do usually stick either open (if you're lucky - just means your block runs too cold) or closed (if you're unlucky - means you'll overheat in traffic when your radiator doesn't kick in!).
If it's the sender it's a cheap, quick job.
