hey guys i really need some help with this problem , my brother has a 19996a4 2.8 quattro has been 2 times after a hard rain the car is full of water inside on the pasager side fron and back. i mean is not just wet is full. what u guuys think is this water comes from? the windows are closed and the sunroof. please help thank you all

 

below the windshield is a drain point and gets blocked by leaves or dust if it gets blocked the water overflows into the fan area ( quite common on parking under trees )

 

thanks i will gochek it now

 

You have to take out the battery to access that drain BTW.

 

if its a 19996 YOU ARE SUPPOSED TO BE FLYING!!!! jk
