This morning I was driving and noticed some water leaking/spilling out inside the cab under the dash where my feet are or the passagers side depending on which way the car turned (U-turn L or R). This is really concerning me because I am fearful of it smelling or possible mold growth. It was raining but this has happened when it is not raining. Someone please tell me I am not the only person to have this happen.

Predicted Possibibilties:
Condensation from A/C unit
Pump failure
Automatic Car Wash jets (I need to start washing by hand)
My car hates me and likes to **** on me
Fountain of Youth

Weather today:
Raining, 41F (5C) typical Houston, Tx Weather

Knowing the 80 degree weather yesterday I suspect the drains for the evaporator core have plugged.
Might be a day or two before the AC will be needed. But park on level ground with AC running.
Look for two puddles under car. Takes about an hour to clear.

Bobby,

Check this link out for info on cleaning the A/C condensate drains, ALSO check your upper cowl drains, and while you are at it clean the sunroof drains.

I think this may be exactly what I think it is. I will check it out asap. Stay tunned for final diagnosis and prognosis

@ Bobbymireless
first : you have to check if the evacuate system(drain) for raining water (blue part in attached picture) is ok
second : cleaning out the evaporator drains for A/C (I attached another pictures about what happened to my car at Audi workshop in Halle, Germany)
Best regards,

Exactly what sputnik wrote; had the same issue with my S8 after prolonged AC use - ice cold water would spill on my feet (brrr)

Took today off to fix. I've been following other and your similar suggest. Super helpful. When I pulled the drain I had a bucket ready and ending up pouring about a half gallon (2 L) of water on the passages side. Taking a break now and about to start on the driver side.

Nothing like a beverage break !!!
