Wet floor drivers side - where are the drainage holes on the underside

[sundstei]

So I found my poor Pepper with wet pants on the drivers side, and I have read all the different "wet carpet" articles from everyone relating to both ac leaking and the drainage from the cowl boards being stuck.

Since its a wonderfully warm day here in Warsaw, I decided to just do some quick testing and I soaked the front windscreen with water to see where it would go. On the drivers side.. nothing.. and on the passenger side I found it to leak down around 20cm back from the front wheel. However I poured probably 20 liters of water on the windshield and only something like 3-4 liters seemed to leak out on the passenger side.

Reading other articles it seems like there is supposed to be some form of drainage on the drivers side as well... and I should stick something up the hole to check that its clear. Looking under my Pepper I can only see a few little holes, and none of them seem to be the right one.

Where EXACTLY is the drainage hole supposed to be???

Here is what I see under the drivers side :

The front cowl drains are located behind the wheel well liner towards the rear. You need to remove just the rear bolts of the liner to access the drain. I just pull them out of the body,clean them,flush loads of water through the cowl and reinstall the drains.

Thanks! So I spent the good part of Sunday now to get the whole well liner off and have a look behind it. There are tons of tubes going around there between the wheel and the door, but nothing I could recognize as a drain.. how should it look? Is it a tube or just a hole?

This is a Touareg but the same bits.

Sorry I could attach the PDF file. I can send it to your email address if you pass it along.

Must be the day for wet floor pans. I found my passenger side floor pan soaking wet this morning. Of course hurricane Irene just went over top of me last night...

I found that my headliner seemed to have a stain that I didn't notice before. I didn't by the car new so its possible it was there .. but doubtful. The stain was in the right front corner of the headliner surrounding the sunroof.

So I proceeded to use compressed air and blow into the drain tube. I also pulled the plug on the passenger side and blow upwards towards the sunroof. I did not do the same for the drivers side.

Would someone say if they think I fixed the problem? I find it really strange that the drain plug (at the end) has a pinched design. Can someone also confirm that it should look like that?

Thanks

Thanks to wvicary's PDF I found it to be looking like this :

and when draining :

Thanks ever so much for the help!! :thankyou:

Work completed and the water is running nicely down on the ground. :cheers:

Was a h... of a lot of stuff stuck in there. One thing: the photos are from a Touareg, but on my Cayenne Turbo there was a lot more tubes and cables going around inside the wheel well, so the drainage was not that easy to see unless you knew what to look for. But of course in the identical place as on the photos from wvicary.

So it is the drain behind the drivers side wheel liner correct?
