Water ingress top of drivers window

Afternoon everyone

I have water coming in through the top right of my drivers window and dripping onto window switches and into footwell.
I have done the following trying to rectify it.

1. Carried out a window reset
2. Checked all rubbers and seals around window, all look good, no gaps and window closing tightly all round.
3. Adjusted and re adjusted window height, and angles as described in a members post numerous times
4. Checked windscreen rubber drain holes, all clear.
5. Cleaned thoroughly and gummi pledged all rubbers
6. Checked for water ingress from door membrane, all ok

The passenger side is fine and has no leaks, despite having a screen rubber drain plug missing.

7. Took the plug out of the drivers side and tried that, just exactly the same, no difference, still leaking.

It does take a while for the leak to start, but when it does it drips in constantly.
One thing is really confusing me tho, when I’m sitting in the car like someone with nothing better to do when it starts to rain and the leak appears, if I literally just drop the window the slightest smidge the leak stops🤷‍♂️
The leak starts where the roof rubber seal and screen rubber seal meet up, I will attach some photos of where .
First photo

I served my apprenticeship at a Ford main dealers 40 odd years ago, MK3 Cortinas etc etc which were renowned for water leaks and I know how difficult they can be to fix.
I know my Z4 E85 has aging parts, but I’m hoping maybe someone can throw some light on the issue.
I’m still looking for a spare drain plug by the way.
It’s 3.20 and I’ve sat in my car for 2 hours in moderate/heavy rain and not a drop of water has came in 🤷‍♂️
Kind regards
Dave

Did you do the adjustment where you take the door card off and roll the window down until you can see the big torx screw through the hole near the bottom rear edge?
That is described as being to lift the window in the frame, but in fact you can also move the whole window forward while that is loose too.
Check the rear edge of the glass against the rubber seal and see whether one side is further back than the other.
If so, give that adjustment a go to move it forward.
I solved that exact same issue for someone only last month.
 
No I haven’t tried that yet, but have tried absolutely everything else. I will give that a go tomorrow and see if that helps
Thankyou for your advise, I appreciate it👍
Cheers
Dave
