Just wondering if anyone would be able to identify all water drain locations?
Background…. Found some water in my right passenger side front and back footwell. Trying to d diagnose where it’s actually coming from. Going to starting looking this weekend but would
Like to know all possible causes before I start.

Same I would like to know as well. I know one of my sunroof drains is plugged but It appears that water actually seeps in through the door seal? I posted a thread on here about it ended up sliding in the door latch a bit and the doors snugged up and it helped a lot with the door seam leaks. but water can still get in through there. https://forums.tdiclub.com/index.ph...-getting-water-pooled-up.530908/#post-5826432

There are just too many to list....
... that took 12 seconds....

To find, cut, and paste...

Google is amazing. ;)

"A6 Golf sunroof drain" ----> image --->

But to help you a bit more, the A-pillar trim once removed will allow you to see if the tube has come off of the lower grommet, which depending on where it is leaking in, can be the most common cause. The tubes shrink over time. They don't seem to come off the drain tray up at the roof as much on the A6.

The drain hole of the grommet is inside the cowl chamber, you'll need to lift it up to see, and the passenger side has a little rain guard that will need to come loose.

The rears are usually less likely to come loose, and more likely to just be clogged.

You have to be very careful with clearing any debris as to not detach the tube from each end.

The rear drains are accessible after the rear fender liner is removed.

Thanks for the detailed reply and diagram. I know, i know. i spent many of my teenager years on forums when i was tinkering with early distros of linux and was pointed to this page more than once https://sadeq.ir/jfgi/

Thanks for the replys. I ended up finding a blockage in the lower portion of the right hand pillar sunroof drain. It was backing water up and causing it to go in one of the sunroof rails and then flowing all the way down to my passenger floor. Crazy. 🤪.
