Is my coolant sensor busted?

I cannot remember for the life of me, so help me out. Does the coolant sensor sit in the middle of "L" and "H" at idle? I know it does on my girlfriend's 1.8T, but I can't remember on my 2.7T. I just drove 15 miles in 100F weather and the thing didn't move. Verdict?

TIA,

-st

Bad sensor. Common problem. Just replaced mine last week.

Gauge should sit right in the middle once you are warmed up. Never lower, never higher (makes me wonder if it's a real gauge or just a binary sensor.

Warranty obviously covers it.

I too have wondered if it was a functioning gauge until...

...I was climbing from -282 to +6000 feet out of Death Valley a week ago...at 75 mph, with the AC set to 70....and it was 114 degrees (45.5 Celsius) outside!

The water temp needle crept up 1/2 of 1 notch above the center point and the oil temp went from the usually pegged 200 to almost 225.

It works!
