Hi,
As the title stated after rain I have water on the driver side floor. Anything you guys suggest that I can do? I don't see any more materiel that is also wet and I have no clue where it's comming from...

It's only on the driver side...Any DIY??

Anyone?

if so, could be related to opening of teh ECU. In teh early days of B6 tuning a few careless installers contributed to similar water leaks.

No mods... I oppen the ECU Plastic box to verify the seal and everything looks good....I put everything back together and still water inside....

Maybe the sunroof drainage is clogged

The plenum water drain tube/s could be clogged with leaves and similar debris, provoking obscure leaks like that. The ECU box to body joint is never submerged under water with proper water drain tube function. Test using a garden hose without a nozzle, directing water into the plenum vertically from above, place hose within ~2" of the plenum floor, pointing down. The drain tube has a rubber "duck bill" one way check valve on the discharge end, trash gets stuck at the one way valve even with a clear drain inlet. The drain tube should flow at least 1 liter/min. (guess-timate)

Possible stone could have dislodged or something

Has the windshield been replaced?
