AudiWorld Forums - TT running hot?

Have a 2000 TT Quattro with 58K miles on it. Concerned about temp readings. After only 15 minutes of summer (80 degrees) stop-and-go driving, temp climbs and needle moves one click to the right of middle position, ( one click past 12 o'clock position). shortly thereafter, fans kick in and temp gauge cycles back to 12 o'clock position (needle straight up again). I can run the car at 80 mph for over an hour and the temp gauge stays in the middle position. So my question is, is it normal for temp gauge, and I assume running temp to fluctuate that quickly? Is this a normal occurrence for a 2000 TT Quattro? I am certainly no expert and any help greatly appreciated.
