Wind coming through driver’s door with wind rattling!

[Mustafa Isa]

I have an Audi A5 2018  and everything was perfect! Today, when I was driving I noticed wind rattling coming from my door and also cold air! It's winter time now so it's cold and I can feel the cold coming from my door's side and I'm a bit concerned! It was perfectly fine yesterday so I don't know what happened! Has anyone experienced this issue before? Is there a solution or anything to do?

Is it to do with the mechanism that controls the the window going up/down when opening/closing the door?

Hello Mustafa,

Thanks for joining. 
Is it as simple as a significant drop in temperature causing the for rubbers to be less flexible? 
Kind regards,

Gareth.
