It’s been a while since I had my sliding door apart but on the T6 there’s a tundish under the door handle mechanism because it lets rain in. There is a flexible hose attached to the tundish running to the bottom of the door to drain the water. Has it got anything to do with this drain?

Rain can get in through sliding windows even when closed and / or door handle if the tundish inside has separated from the door skin.

It's not actually for the sliding window, it's normally attached to a catch 'tundish' for the door handle. Without it, any water getting in via the door handle will be running down inside the door skin and collecting at the bottom of the door.

@t0mb0 I hadn't spotted that tundish to the right of the cylinder and was going to chime in that it was just a conventional gravity cylinder... is it a pressurised cylinder I wonder and if so why unless there was going to be a gas or oil fired system to go in originally? Could be low water...

Is the attachment point obvious to find on it?

If it’s not leaking from the sides of the tundish then the pipe is blocked. Try disconnecting the pipe from the tundish and blowing down the pipe.

The tundish collects water that passes the door handle. Yes push it back against the door skin. I think the tube is clipped towards the bottom of the door. The photo is how VW left mine. It just pushed back onto the tundish.

There’s a tundish to collect water that leaks through the sliding door handle, the non setting adhesive / sealant can fail and the rain leaks through the door. ‘Normal’ drainage from the tundish is via a hose to the bottom of the sliding door and out past the door seal. This has already been...

...down the drain through the seal route it would be far better to prevent the water intrusion in the first place. There are two known paths; 1. Sliding window seal - this can be easily improved with application of silicone grease. 2. Door handle tundish adhesive - just re-work the adhesive...

Thanks. Never heard of a tundish but I'll check it!

...if you have a genuine hot water leak somewhere. First thing I’d check is the temperature/pressure overflow safety valve on the cylinder, if this is constantly ‘leaking’ you will be losing energy down the drain there. Stick a piece of tissue in the tundish there - if it gets wet you have an...

That’s the tundish. From factory there is a sticky seal that stays soft. Mine has come away a couple of times and I’ve just pushed it back and it’s stayed put. Also check the drain tube is still attached and also running clear. Last time I had my door control mechanism replaced under warranty...

...a small swimming pool in the sliding door! Looking inside the door and there's barely anything in the bottom so it's not the door handle tundish that's leaking. The sliding window groove looks pretty dry but it's 100% coming from the detached drain catch so I can only think that at some...

Ok- so you mean just push it back against the door itself? What is supposed to drop into that tundish? Also you can quite see how the drain tube is attached to that can you? When I pull the drain tube from the bottom of the door it wont come- almost as if it’s attached to something but you...

...the other drain holes. So I'm fairly certain that isn't the source of the water. Inside the door, there's a very obvious leak from the tundish around the door lock. The hose is clear and water comes out the hose. And the seal appears to be OK. But it's still leaking a little. So that's the...

I had a look at mine at the same time as fixing the sliding window drains. I believe the plastic tundish is held to the door skin with the same non setting adhesive used on he window drain. If you are going to repair I think that it would need to be removed and properly cleaned, this is based on...

...job but it took multiple attempts to repair mine, access is achieved by pulling off the lower plastic trim. This drain joins the rubber tundish that collects all of the water that gets in through the door catch and it eventually drains out of the bottom of the sliding door via a hose and...
