It was leaking even before I knew the moon roof was recalled and took it to VW to be fixed. The next heavy rain came around and there was a pool of water on the floorboard behind my driver's seat. I'm stumped and so is everyone else. The car is bone dry everywhere but that floorboard. Today's heavy rain in South Louisiana put almost half an inch of water back there in the 6 hours I was at work. And yes, I have sat in my car in the heavy rain with no luck at finding the source. Its like gremlins come and dump a cup full of water in my car.



Any idea you have to offer me is welcome!!

 

I have the same problem with my 02 1.8T, most research pointed to clogged up drain lines from moon roof to the the A pillar where the drain plug is(door hinge area). Could also be one of the hoses is loose.
