2016 T6 cab water ingress! ☹️

New members.
Apologies if not posted in the correct sector. Still finding our feet around the site and van!

Recently acquired our Van late last year. Unfortunately, during heavy rainfall we find water dripping in down the very side of the near side A post. Initially, I thought(previous passat owner) the ingress was coming through the scuttle chamber below the windscreen as did my passat in previous years. Checked here and can't see where it could be entering.
The van has a pop top roof, and from discussions it has pointed to possible leakage there and running down the inner A post.

We booked the van in to check this and thought it was resolved by resealing the bolts on the roof.

Sadly, during the recent heavy rain it still appears to be pouring in.

Photos attached. Unfortunately, I'm unable to upload a short video from my Samsung phone!

Any advice would be gratefully received.
Al.

Failure of the windscreen bond?

Unsure?
Water runs down the side of the A post. My other thoughts were possibly a failure of the door cable boot as in the photo but the cable is dry there?
Water building up in that open chamber.!

If the roof bolts have been done then as @Sasquatch said it’s most likely the windscreen is leaking

Will take a look once we get dome dry weather.
Thanks

Is it low down ? Have you removed the Apillar trim to see if theres water coming in up high and running down ?

Nothing on the surface of the there. It's coming from the inner channel of the A post and weeping in through one of the cabling entry points.
You can see water residue inside the pillar when you remove the door mirror ducting.

Mind boggles!
