I'm not sure if this is the document you're referring to, but it may be useful all the same.

I'm not sure if you've read through all the comments on here but United232 disappeared after some time. That makes it difficult to know how successful his treatment was long term. Others have tried it with varying degrees of success, myself included.

In a nutshell 232's approach is to remove the fly catcher/windbreaker net (call it what you will) from the sunroof and appear a low viscosity sealant to the gaps in the structure of the frame. It's incredibly difficult to work with, has the potential to drip through and stain your seats and people are generally over-eager to apply more than is required.  232's report also fails to address the possibility for multiple ingress points. Whilst I followed 232's suggestions, I did not have real joy in eliminating water ingress. Water can make its way past the main roof seal and bypass the a-pillar drains regardless of using the 'miracle' sealant. I suspect these are real points of ingress and you should inspect the adhesive between your car body and the main seal. If it's compromised, it'll let water in for sure. 

 

Ultimately you need to know what you're dealing with (i.e. where your leak is coming from) before you can tackle solving it. That may mean gutting your interior. That's how I fixed mine.  I found an addition leak path and have since prevented ingress. It's been leak free for months in all weathers. I still haven't replaced my headlining though and will monitor for as long as I feel necessary.
 

232's report is good for highlighting a few key hurdles in taking your car apart. It seems daunting but once you start, it just becomes a logical progression of taking more and more out. Very much like a jigsaw.

It's a fair while since I've provided an update on Weti so here goes - I stripped the interior to just the front seats back in October when I first noticed my problem (no carpet, sound deadening or headlining) to understand where the water was coming in. Over the last 6 months or so I saw water coming in as the OP described and like many attempted to resolve the issue with Captain Tolleys, with limited success. Around 6 weeks ago I made a further modification to the sunroof rubber using a bicycle inner tube (I shared this proposed solution back in October but have since refined it). Thankfully, I have not had a drop of water through the sunroof since the revision. If it withstands this evening's absolute downpour (I have no reason to expect it won't) I'll reassemble the interior and share with the rest of the group what I have done providing there is still a big enough audience. 

How have other group members been getting on with their Weti issues over the Spring period?

 

Hello everyone, I've joined since some months the family of yeti lovers/wet haters you've been in.

 

@Weti's approach seemed to me the most successful till now, has the leaking ever resurfaced since May? Could you eventually provide the full range of solutions you adopted to deal with it?

 

Thanks a lot to everyone for sharing!
