After thirty minutes, ac vent on passenger side starts blowing very hot air. Ten minutes later the ac vent on driver's side does the same. A short while later the two center vents blow hot air. The next day is all starts over. Audi sent out a technical bulletin tb 2013883/1 doing a mea culpa stating it was their fault. When they manufactured it they got metal shavings from the engine into the ac pump. But they are not willing to fix it. I have an estimate for $1300.
