That's why other Dieseasels are fitted with an auxiliary device to heat up the coolant in cold temperatures...

I have a similiar problem with my 2001 tddi mondeo.
If driving it hard the temp sits perfect at half way but cruise about and it drops down to about 1/4.
I change the Stat but its the exact same.
Could that be the temp sensor packing up or would it just stop working all together?
I think the sensor for the temp is on the side of the head and by the looks of it you have to remove the pulley on the end of the camshaft that runsg the power steering to get the sensor out?

I have had very little bother with mine
There is common issues or things that go first with any car tho.
Mondeos just have injectors or clutch/flywheel is the common thing.
Mine has nearly 140k on it and still fine.
My G/f's uncle has a mondeo ttdi 2004 with 440k on it with no major issues apart the the clutch which is expected

I thought I'd pass on my experience with a my 'cool running' Mondeo.
Last winter I had the same problem with the car not warming up properly and changed the main thermostat for a non genuine item. (the Ford one is around Ł50!!!) This made no difference whatsoever. The weather warmed up soon after and as I wasn't cold any more I gave up. Then came the current cold spell and the problem remained so I bit the bullet and bought a genuine one, no change and fifty quid worse off.
Looking on various forums I discovered the second oil cooler thermostat and bought one from Mr Ford. (just under Ł20) After fitting it this afternoon my temperature gauge runs smack in the middle and the heater is toasty, yipeeee!!!
The hose that exits from the oil cooler enters the radiator on the right hand side about 1/3 of the way up and should remain cold until the engine is warm, mine was warm all the time so was taking heat from the engine to the radiator even though the main thermostat was closed. When I removed the old oil cooler stat and blew down it it was open even though it was cold. I would guess that to eliminate the second stat as a cause of over cooling the hose from the oil cooler to the rad could be temporarily clamped with a brake pipe clamp or similar to simulate the stat being fully closed,
I hope this helps someone else to stay warm this winter, good luck!

I just changed my il stat and it hasnt helped
Next thing ill do is replace the motorfactors thermostat with a genuine ford one.
The TDDI engine isnt quite as easy as the TDCI i with the fuel lines from the pump to the injectors so i had to remove the inlet manifold to get access but it was quick and easy to remove.
