Sound like thermostat is definately faulty and your car is running cool, this is a very common problem on this engine. This accounts for the gunge in the engine as the condensation naturally produced is not getting burnt of so is emulsifying with the oil. Downside to all this is thermostat requires timing belt removal which makes it an expensive job. Change the coolant sensor too just to make sure. Also clean or renew EGR valve every year, apart from this these engines are pretty bullett proof.

There's a quick and cheap fix for the thermostat, which is documented here:

I think the Swear filter caught my link above.

The fix is described here too, but more long-winded:
