Is there any chance of clearing out all the leaf matter from the insides of your wings with a jet washer?:D

I'm thinking a few sessions with the lance aimed down that hole should break up and disperse all the rubbish that's in there?

Once clear you could follow up with some wax oil??

.........any chance or do I really need to just pull the wings off?:(

Good idea but there's no where for the debris to go hence why stays in there mate when doing my wings I put hoses on the hole that causes the issue there is a thread on here somewhere T:

Give it a go tho always worth a try T:

Is it possible to open the wing up and flex it outwards without removing the bottom edge?

I'm think of trying to get it just wide enough to get the vacuum cleaner down there.:)

While the front wings are off my van, and inspired by a thread on here that I can't find anymore I decided to install drains to the scuttle.

It seems the problem is the open holes at either end just allow water and debris in behind the wing where it rots everything out.

Here's what I did.

First, get a couple of female 20mm conduit adapters (couple of quid from Screwfix):




And fix them onto the existing holes in the scuttle. They fit really well.



The underneath, push some 20mm flexible conduit into the adapter:



And secure the conduit back using these self adhesive nylon blocks and cable ties



Route the conduit forwards to a suitable place where it can drain away safely and that's all there is to it T:

yes, is a silly vw design. trouble is the water takes rubbish down too
found the area around the holes at the side of the battery & behind air filter had rusted - yours look ok, so sealed the 2 holes in the scuttle, drilled a hole at centre then a T spout & pipe to below the engine similar to what you did.

just looking at this a bit more
to the rear of the drainage holes there seems to be a gap (haven't had the wings off so difficult to see) where water can still get down into the wings
little wonder that there are so many with arch rust problems
no matter how much you seal the wheel side of the arch, water is causing the rust from the inside
thinking of pumping in filler/silicon at the ends of the scuttle to seal the gap, but access is difficult

seems a ludicrous design by vw

Yep, I forgot to add to this thread.
Last weekend I gave my van a wash (it's been a fair few months I:) and so I though after weeks of dry weather the last thing I want is fresh water going down there..., so I sealed the holes with duct tape as a temporary stop.
I was surprised to see the run off water still draining away and then realised the seem is open. The good thing is it means I can permanently block up the intentional drain holes as the water drains just fine down the seem. Also the seem is slightly less likely to let leafs and other rubbish down there.
Once I've cleaned out the arches I'll put some sort of filter material over the whole seem area to ensure that rubbish stays out.

While getting into the van today I noticed there is a gap at the bottom of the wing, for drainage and possibly an escape route for debris.
On the passenger side, at the back bottom edge of the wing. Where the panel break is on the wheel arc. I noticed some leafy type things sticking out towards the door, and it looks like if material is broken down enough it could make it's way out of there.

I'm wondering now if some targeted jet washing could mash up all the material in there and blast it out through the seams afterall?

Well after spending the last 2 afternoons cleaning and polishing the van, decided to attempt to clean out the front wings(I know it was the wrong way around) removed the airbox and cleaned and cleaned(Ended up using a green twig (didn't want to scratch the paint and it was the only think I could get all the way though)), Then removed the side lights and front panel and finished off the right side and did the other side.. Finally I took the hose and washed between the gap of the front arches until it ran clean (you have to open the front doors to get the hose in) I could see all the way through just and looked pretty clean.. No rust could be seen, but removed at least 2L of leaves and compost. Decided for now to leave the foam "moss catcher" out.. (the airbox adapter thingy in the wing)

Not sure if I should replace it or just add some some mesh or both

followed a tip on here that later vans wings are flexible enough that once the upper and a pillar bolts are out, plus indicators off, you can get your arm in to clean out the compost.
found my foam air filter thing in a right state but when left out didnt look right so ive fiberglassed the inside, quick skim of filler and a coat of satin black paint. no more moss garden and looks oe.
