Hi guys and gals, I've got a bit of a dilemma here. I've got a 2.0tdi 143. My car isn't warming to 90. It's getting to the mark half way then going up a bit when I'm going up hills, then down when going down hills. I thought thermostat so took it in to Audi a few weeks ago for warranty repair who diagnosed the stat was shagged and replaced it last Friday (warranty runs out on 17december :O). Today it's doing the same thing!
Please help :'(
