I own a 1998 Audi A6 Avant Quattro Wagon. Whenever it rains my front floorboard gets wet on both the driver and passenger side. When I apply my brakes aggressively, water rushes in from the roof.

What could be causing all this water intrusion?Is it possible for me to fix the problem(s) myself? At this point, I'm open to any and all suggestions. Thanks.

 

probably either leaking in from the sunroof or front windshield. whichever one it leaks in from, just get it re-sealed..should solve the problem.

 

I think there are drain path ways from the sun roof that run from the roof down through the a pillar and drain out by the wheel well. They can get clogged and cause what youre talkin about. Home Depot carries mini "snakes" that are normaly used for uncloging sink pipes. You could try something like that if they have a small enough one.
