Ive got a ton of water leaking under my dash on both the drivers and passenger side. My indie mechanic cleared out the evaporator drain hoses on either side and the leak continues, mainly when I run the AC.

He explained that there is some kind of box or container inside the dash which collects water and drains it, but commonly on the Audi's the box cracks due to heat or age and leaks. The fix is to remove the entire dash to get to the box and replace it, he estimates a full 2 days labor to do this.

Anyone have any suggestions?
