hopefully will stop leak ....

Appreciate any update if that works. A close friend is looking at this S2 project with idling issue and sunroof leak. We'll take a closer look after the brake pads and moto metal wheels installation on the current truck project.

Make sure your drip tray is in place, under the back edge of the sunroof panel when it’s closed. You should be able to see it when the roof is tilted up. If it’s not there it is probably stuck down the back of the cassette and you can fish it out and clip it back in place.

Unfotunetely drip tray is in its place .... So last hope is sunfroof seal...

And the drain pipes are clear?

[sailaz]

Yes, all 4 water drainage hoses (no.2 and no.3) has been replaced with new ones and tested - all good.

Good.
Now I discovered another way these sunroofs leak. The surrounding inner part is sealed with a special non hardening sealant. If it's disturbed in any way, water will come in around the top of the a pillar. I ended up removing mine and found some rust underneath. I cleaned it all up, painted and 're sealed. So far it's been leak free. I used tiger seal.

Maybe You could show on diagram where that hardening sealant is applied ??

You can see here the rust getting treated.

These stainless runners also need to come off and get sealed. You need to be careful that you don’t get any in the cord track which is greased. I used silicone grease in the track.
I put some neoprene tape under the outer cover. Take it all apart and it’s all pretty self explanatory.
More pics in my thread I think. Check my Nothelle N300 Re build thread.

Thanks for detailed explanation.
I have inspected this part before installing last (3rd) sunroof, and there was no rust, nice clean grease everywhere .....

Thanks Dave....this just explained a mystery I've been chasing for years. Even went as far as to reseal my windshield. I guess the strong tropical sun, "hardened" the non hardening sealant
