I think this might be the case with mine as well, wrong or bad H2O temp
sender.
Craig and I have talked about the fact that my tt motor appears to be
running too cold (barely comes out of the top of the box when hot).
I have left the car idling and even when the rad fan kicks on the temp is
only a little out of the top of the box.
On the freeway with cold air going through the radiator, it will drop down
to the bottom of the box tho'.
I recently replaced the sandwich plate/thermostat oil cooler with the Euro
GTI setup with a new thermostat and it runs a little hotter now but not
much. (Oil temp changed from average of 180* before to 190* now...oil temp
is still too cold IMO.)
I am planning on replacing ALL the senders on the engine as soon as I score
employment and also installing a REAL H2O temp gauge.
This is something you might consider as well Rich considering what that
engine package would cost to repair/replace.
