Autodata software (maintenance database) says something about 80ºC thermstat in some TDI but I thing it's not true and maybe a mistake, because original parts for engines from 1997 (I/ve seen) to nowadays use 87ºC ones.
Your car is wasting fuel because of your thermostat opens at lower temps and maybe never closes at all.
If you were able to measure the fuel saving with upper grill blocks you will appreciate the big improvement of your thermostat change.

Thanks for that..
My car is not a TDi though, its TD, the AAZ engine- I'm not sure what the thermostat is for that engine?
