      My 1.8T seems to run hot to me, but I think I may just be a little paranoid. When Sitting, the temp seems to creep up just a bit on my aftermarket VDO gauge. The stock gauge in the cluster never moves from the middle. I find that gauge to be very misleading anyway. Here is a picture of me cruising at probably 50mph on a cool morning. Looks to be at about 200 degrees F.



      Usually when I'm driving, it is a bit cooler, and it reaches that point when sitting at a light. I just feel like i remember it staying more around 180 before my rebuild, and now its more around 200.

      Here is one today after shutting the car off. After a couple minutes the temp went up to here...

      for what its worth, the stock gauge has a big dead zone around normal temp. You can see it if you log the data with VAG-Com, the temperature will say 190 on the gauge, but it can vary quite a bit without the gauge moving.

      Right, that's why I am very happy to have an aftermarket gauge. I have seen 250 degrees on the aftermarket gauge before the cluster gauge even started to move.

      If you have seen 250 degrees, then something is not right in your cooling system.

      After you shut the car off, of course the temp will rise, as the coolant is not being circulated anymore.

      If you want to add extra security, take a look at the coolant pump that is OEM on automatic 1.8T's

      IT only saw 250 a very long time ago for only a second when the waterpump impeller broke.
