Any plans to drill a hole should also include a length of plastic pipe which is a push fit into the hole and is routed to a place where the water can drain safely away. Something after the syle of a retractable sun roof drain. However as with sun roof drain pipes they may need clearing periodically. But then if VW didn't feel it necessary...

Absolute pain and it was the only area that I had to weld in sections when I bought my van. Well waxoiled now but why are these vents needed anyway? Not sure so may be someone will answer that (mine is LPG'd and takes in air from the engine bay so no airbox). I thought of the 'hole' too but this will only work if the van is sloping in the direction of the 'hole'. If the van is used regularly then the water will probably evaporate naturally. Dry it out and waxoil it for the time being. Might make some plastic 'clip on' covers........ :idea

Most of the water actually gets in there when you're parked. The runoff from the roof gutters occasionally runs straight down the side of the air intake and takes a turn inside. In heavy rain that could be several liters.

There are several threads on here on how to deflect that (with a bead of sealant, for example or a more elaborate metal deflector plate)

Access to it is easy enough, just take of the rear lights

and for the rear corner you take the route through the engine compartment.

Some vans have sound deadening foam in there ...that needs to go while you're at it.
