Everytime it rains heavily my
A4 (1998) gets a major water leak inside the car. The driver side floor fills up with up to several inches of water. I'm starting to get worried about serious water damage.
At first I thought it was a bad seal between the lower windshield and engine compartment, but I sealed it and it's still happening. There is a great deal of water still getting into the engine compartment especially underneath the battery and brake pump. It must be getting into the interior some how.
Any ideas? It's driving me crazy.
