My 98 tdi Jetta was doing the same thing until recently.  When I first got the car the engine had just been refreshed after a broken timing belt and a new thermostat had been installed.  Talked the gent who had done the job to replace the thermostat because I thought the first one was bad out of stock.  Still no joy when things got cold.  But recently I had to reseal the top covers on the IP and had to reset the injector quantity.  I am pretty sure that the iq is not quite right because of the decrease in fuel milage around town, but on the plus side I will get up to temp by the time I have travelled the 10 miles across town most mornings.  I am of the opinion right now that the iq was set really low and there wasn't that much heat being produced, especially at temps lower then 20.

With the outside air temps in the 15-20 F nights and upper 20's days my
'98
Jetta is running way too cool, although the heater seems to be working
pretty good, but the temp gauge just doesn't seem to want to leave the
bottom of the guage.
On slightly warmer days I've gotten it to almost mid gauge (normal).
I'm put some cardboard in front of the radiator, but wonder if someone has
already figured out just how much cover it needs and at what temps to do
this.

Thanks,
