It could be that its just the cold temperatures. Mine at the moment driving round town does not move from the botom, faster drive on the motorway then it moves up to just above the first line.
How long have you had the car?
Mine is a 200tdi with a higher rated thermostat.

is there a thermostat in it?
My 200tdi Disco is very slow to warm up according to the gauge. I have fitted a new thermostat and it still takes about ten miles town driving to get warm. Get on the motorway though and the heat comes through instantly and the gauge comes up to half way. I'm wondering if the sender is wrong but dont know what colour it should be.
Going to flush the lot out when the hose pipe thaws..

The thromostat keeps the system cold
Put a new sender in yesterday. Still no movement on gauge even after 30 miles!
Check you have electrical continuity and that the guage does work by shorting out the wire from the sender to earth
This should show maximum on the guage with ignition on, but proves all is working
Do you have warm air fron interior vents?
Are radiator pipes warm / hot?

I am getting warm air. What do I have to do to short the wire from the sender to check for electrical contnuity?
The thermostat keeps the engine warm, holding back the water in the block until it gets up to temp then it lets it go to the radiator for cooling.
Just pull wire off the sender on side of engine, then either
1/ With assistance - one person watches the gauge while the other holds the metal connector to the engine block, with ignition on
2/ alone - get a wire and connect up an earth point to the connector, then go and turn ignition on and watch the gauge
