I opened the sunroof to access the drain holes. Poured some water in each one. It duly came out of the hole directly under the respective A pillars as per photo.

Attachment 162650

So they are not blocked which is good.

Alternately this: The sunroof seals - 22 years and 50 million corrugations later - are not what they used to be. Is it possible that in very heavy rain that the leak around the seal exceeds the capacity of the drains to get it away..it then backs up into the pillars and finds a way into the car?
I wonder this because if I press around the seals with the roof in the closed position there is a fair amount of movement.
Took a short video but cant upload it here?

Otherwise I suppose it could be a leak around the windscreen somewhere as it is new as of about 12 months ago. But the corners look ok and where it didnt I have siliconed it. But I suppose it could be getting in anywhere along the top seal? I will get the hose and squirt some along there (ie hold the rubber seal away from the roof and add water) to see if I can see anything..another day.

Have any parts of the seals gone hard?

You checked the front drains, what about the rears?

There are rears too? I wonder how you get access to them- because if they are at the rear corners they are obstructed by the roof itself when opened. Where do they drain to?
It is just a single sunroof (roughly 400X600 at a guess) .will it have rear drains?

I would suspect so.

Yep, there are. You can't see them with the sunroof in place.

Ah right.
I can get access to the lower parts of those hoses so I will see if I can push something up through them. Thanks for that. i knew the sunroof would be a pain one day.

Has anyone replaced the window seals? They are readily available even on ebay.

I hate sunroofs. We never use the ones on the Suby nor the L322.

The one in our Peugeot 405 took away a lot of the headroom.
