Rainwater Getting Into Cabin Through Seam In N/s Footwell

[keeyth]

After weeks of head scratching I have finally found out where the rain water has been getting in to the passenger footwell of my mk2 2003 tdi, when water is poured into the scuttle panel area you can see water bubbling out of the seam joint arrowed in the picture, It takes a few minutes from pouring the water before it starts to run out of the seam joint, Now I could just put some sort of sealer over the area to stop the water getting in but chances are the water will just find another way to enter, Is there a particular area along the bulkhead where it is possible for the water to get in? , I have removed the black scuttle panel and ran a hose along the area just below the pollen filter housing and within a few minutes the water starts to trickle out the seam in the footwell

Hi Keeyth

 

Sorry to be critical mate but could you add another piccy so we could see the exact area your indicating as these leaks are becoming more apparent lately.

Probabbly worth checking the scuttle drain behind the wheel arch liner. Theres info on doing so in the faq section. If the water isn't escaping as its intended to then it tends to find its way elsewhere.

If it is blocked unblocking it would be your first task. Once your happy its unblocked it may be worth sealing any gap you can see still there (the trouble with sealing it first is you don't know why the water is ending up where it is and your only likly to relocate the problem elsewhere!)

if you have a sun roof the drain pipe has probably become detached

It's impossible to get the camera in there to show the problem area at a different angle, All I can say about it is the water is leaking though the sealant right in the corner where the n/s/f wheel arch meets the floor and bulkhead, there is no visible hole or staining from rust, My Galaxy has no sunroof so I can rule that out, I have had both wheel arch liners out and are completely clear as are the drains, I can also rule out the windscreen because the leak can be reproduced by gently hosing water into the scuttle cavity, I am thinking about removing the wiper motor to try and run a bead of sealer along the back of the bulkhead that runs under the pollen filter housing corner to corner between scuttle drains, I don't think water running out of the passenger side scuttle drain could enter the cabin as it is directed away from the affected area by the wheel arch liner

I'd seal it up then see if you get further water ingress. There should be a proper drainage channel there, if this is an added "extra" then blocking it up should see the water go down the intended route. I can't imagine all the water is disappearing down there, if so, you've got a bigger issue!

In addition to sealing the area you've identified (i recommend a neutral cure sealant such as http://www.toolstation.com/shop/p13716)

 

Also check you drains are clear, run a hosepipe into the far corner(s) of the scuttle panel

 

 

use a rod or long thin screw driver and push it up the small drain outlet which is located on the sill lip immediately behind the front wheels to dislodge the dried up mud, leaves and pebbles that often block them up. If you have pebbles and leaves in there (I had), then you'll probably have to remove the wheel liner to remove them sucessfully. Bad design
