Yes, the way shops measure the temperature is with an infrared thermometer. You point it at anything and it gives you its temperature. I heard you may be able to buy one at radio shack for $50. Otherwise go to a shop where they dont rip people off(very hard to find) and WATCH THEM use this tool to see how hot you're really running. Don't swap the temp senosr without actally knowing how hot you're running. My experience is that the gauge is crap and its probably at fault.

Given that most of your cooling system is new you should not be running hot. Read Ben Huot's post earlier today about the cooling system and the new VW temp sensor, very interesting. Here are resistance values for the temp gauge sensor to see if your gauge is operating incorrectly. Don't know if these have changed since VW came out with the new sensor:

32F 5,000-6,000 Ohms 68F 2,000-3,000 Ohms 104F 1,000-1,500 Ohms 140F 500-675 Ohms 176F 275-375 Ohms 212F 150-250 Ohms

I dont know where you are in the mid-atlantic region but I know of a reputable shop in N. N.J. (Hackettstown Imports) and of course there's vanagain in southern N.J.

let us know how it goes and don't hesitate more questions.
