PASSAT B5.5 Water leak in footwell problem

Hello,

This is my PASSAT 2.5 V6 TDI 4 Motion (180hp) that I own for almost 10 years now.

I never had any problem with water entering or leaking in the vehicle, but last friday when I came in the car to drive back home I heared a strange noise like water was flowing inside. First I thought maybe it's just the gas tank that I am hearing, but the sound was way too loud for that. So i tryed to touch the back side passenger footwell and I felt water ...

Good thing that I had a deep cleaner at home, so when I came I sucked out as much water as I could, but I already knew that the water got under the carpet floor already.

I did much searching online, here are some links to the site and videos:

So here is the procedure that I took.

I am not a professional, just like to do things on my own. The language in Slovenian, but I added subtitles to let everyone understand what is going on. In the video I showed how I dried the interior also.

Anyway hope you enjoy it, leave me a thumb up if you did, and thanks for watching.
