A/C Heat Exchange unit leaking water

To all,
I have a 2007 A8 4.2L that has a water leak.
When I run my A/C lately, I get water that drips into the driver and passenger side. When driving I feel water dripping onto my right foot.
After some time driving for long hours, I could hear water "gurgling" behind my center counsel. After getting home, I lifted the weathertech floor mat on the passenger side to find that it was complete saturated in water. It took me over 5 hours to dry it out.
A friend had this issue and noted that it was the drain line for the A/C heat exchange system and that it was probably clogged and back flowing into the cabin.
Does anyone know where I can find the drain line to clean it out?
Thanks and cheers,
Jeremy

For the love of Pete, don't run your A/C until you fix it. You don't want to get the modules found around the floorboards wet, they get very expensive to fix.

Yes, your AC evaporator condensate drains are blocked. Plenty "how to guides" if you search, like here:
