Having had first hand experience with the same water leak symptoms in my
brand new A4q :-( I think I can help. Apparently the inner door seal that
prevents water from entering the inside of the car had been improperly
sealed. This allowed water to run down the window, into the door and then
to accumulate in the side pocket. Since the car was under warranty, the
dealer fixed it. I'm sure you can find info in the archives on how to
disassemble the door and repair it yourself if you are so inclined.
