03 Jetta Water Leak

I'll occasionally notice damp carpet in both front footwells, but mostly on the passenger side.  A mechanic claimed that the problem was a clogged A/C condensate drain line, which he unclogged, but I've had two instances of wet carpet after rainstorms, so it must not be the A/C.  I've hosed the car down (it has a sunroof), but can't ID the source of this leak.  Do Jettas have a reputation for this problem, and what might be the causes?
 
Thanks.

I have the same problem in mine. Also can't find the source of the problem. Mine is at the dealership and they told me that it's out of warranty, so I'm screwed. Complain to VW Corporate.
I think the leak is coming from the heat/ac vents, but I'm really not sure.

Well they found the problem. Turns out I had a clogged sunroof drain. Here is a blog I found that describes the problem:
