W213 Coupe side window not closing issue

[IKik23]

Hello,
About a week ago I have noticed the frameless windows which are supposed to sit flush with one another have got misaligned. The drivers side is perfectly fine however the in the passenger side the top of the window is sticking out, but the bottom is connecting perfect as well. I tried synchronising the windows by holding the buttons down for 5s but to no help.Anyone ran into this issue in the coupes and if so how did you manage to fix it?
Attaching pictures for reference, thanks!

Looks like the window regulator has gone out of alignment - needs investigating by going into the door and seeing what has happened.

Thanks for the reply,
Since then i have undone the rear side panel and you were correct, the window just needed some adjustments on the regulator and all is working fine now.
Once again thank you !

in anticipation of it occuring on my C238 (which is the model you have), do you have any photos of where you opened up and what you adjusted ?
