I haven’t yet, but have only had the car for a week. I do have to say that the AC and the ventilated seats on this A5 are amazing. Seems to cool the car down fast in this 100 degree weather in Kansas City. The ventilated seats cool much faster than my last car. It must be the difference between blowing air (most cars) and aspirating (A5). Reading previous posts before I got the car, I thought that it was crazy that Audi’s ventilated seats sucked instead of blew, but it seems to work very well.

Interesting find. I haven’t turned the HVAC off, but I did notice that in “vent” setting (AC turned off) that the air coming from the vents was substantially hotter than the outside air temperature, even though the temperature was set low. It should not have been blowing hot air. I’d bet our findings are related.
