SEAT Toledo - Leaky rear doors on nearly new car - littlerussell

I have a nearly new (11 month old) SEAT Toledo.

One of the rear doors fills up with water whenever it rains - large amounts of it sloshing around.

Pulling the rubber door seal over the drainage holes (it seems to be covering them) releases the water which literally comes gushing out.

The SEAT dealer, under warranty, have offered to "unblock" the drainage, which I suspect may mean bending the seal a little so that it isn't sitting over the drainage holes.

However, no one seems concerned that this amount of water is running through the inside of the door in the first place (after half an hour of heavy rain, I can get about a pint out of the bottom of the door).

Is it correct that this amount of water should be travelling through the inside of the door? Or should I be pushing to get the window seals replaced so that it isn't getting in there in the first place?

The inside of the doors will always get wet with rain water or washing the car as they are deemed a "wet area" by VAG. Replacing the glass seals won't stop water ingress as they don't create a positive seal, maybe slow it down a little if they are faulty, but not stop water entering.

Possibly the drain holes in the bottom of the door are either partially blocked by wax sealant or the lower door apature seal is out of line pushing it over the actual door seal and covering the drains ? If it's only effecting one door there has to be a reason why as the other doors are fine yes ?

As the Mechanic says, you will not keep rainwater (or carwash water) out of the door. You can only make sure that it can get out easily at the bottom. Poke something soft (e.g.plastic or wooden) up all the drain holes, and check that any weatherseals don't cover the holes as the door closes.
