Hello, Have you figured out what's causing your leak yet? I just had a similar problem with a driver-side leak on my 2003 Jetta wagon during the rainy weather we've had for the last month. Since it's still under warranty, the VW dealer checked it out and said it had defective door seals. They replaced the ones on the driver side, and ordered two more for the passenger side, which have to come from Germany.
I still had water coming in under the dash, especially when the car was parked uphill, so took it back in. They found that there was a clogged drain that was overflowing when it rained, so the water was running into the car.
The carpet was starting to smell moldy, and the windows were steamed up all the time. Hope it's all fixed now.
