Okay folks, here's an "interesting" one...
A few weeks ago, I mentioned that the temp gauge on my '89 90Q had stopped
working on anything but rare occurrences. Since that it was neither very
cold, nor very hot at the time, I wasn't overly concerned with the problem.
On Friday, the antifreeze warning light comes on. I pull over to a stop
area and whip out the handy-dandy jug of antifreeze that I keep in the
trunk for just these occasions. I refilled the reservoir a little full, so
I proceeded to "tap" out the air bubbles in the tank, just to get the level
to drop a bit, which it did. I also refilled both washer tanks, since I'd
just purchased some "Rain-X" fluid in response to the oh-so-cute fountain
indicator which had also come on recently
After closing the hood, I headed back down the road, happy that no warning
lights now flashed. I got a few miles down the road and, suddenly, I
noticed the temp gauge was working. I assumed that this was just one of
those teases that Audi's just seem to LOVE playing on their suffering
owners and that the gauge would fail ("properly"?) when I took the car out
The gauge has worked every time now. Anyone got a feeling as to what I
jiggled back into place? I'm assuming I "fixed" it when I was knocking the
antifreeze tank. Is the sensor anywhere near the tank?
