I think you need to seal down the sides and bottom of the roof drain grommet to stop the leaks.

Yes, and that is what I did. No water seem to have leaked through with the hole plugged. Before I sealed, as you described, the water disappeared in an hour or so. Everything is now back in place and running again. Thanks everyone.

Yes, my rubber grommets are not in that bad shape but still the video is a very good description of the problem. Thanks. What year model of the Cali?
That video was taken by member NRDSRFR who has a T5 SE 2006 LHD but I had similar leak issues from my 2010 T5.1 SE on which I sealed the roof grommet but later found it was the plastic roof cowl repair mastic that had cracked and caused my leak which VW repaired free of charge last year.

I have a 2005 SE. I must ask; What is “the plastic roof cowl mastic”?
I managed to confirm no leak around the grommets but I am really not 100% certain tht is where leak was.

The original front part of the roof can suffer from aluminium corrosion (blistering) and VW used to replace it but due to the expense they now cut out the corrosion then fit a plastic cowl over the original roof which is sealed to the old roof with mastic but this has been found to crack and allow water ingress so from 2019 they have improved the mastic to prevent this (hopefully)

Great explanation and pictures! This is obviously not my case since I still have the aluminum roof front, with some (only a few) corrosion blisters. The pop top has more clear aluminium corrosion in the corners, but I don’t find that as an issue.
Fantastic that VW replaced under warranty after 10 years.
