There is another quirk of the system, mostly related to heating 
rather than cooling. In the wintertime, if you park in the sun, the 
HVAC sensor on the dash will sense a warm cabin and call for cool air 
even though the rest of the cabin may be cold. I think this is mostly 
with C5 A6 vehicles, but ICBW.
