Just a long shot.If you go into your climate menu.Your auto air recycle button isn't set to 'on' is it?.
If it is,that might account for a build up of moisture inside your car.It should be set to 'off' as standard.

Just out of interest why should it be set to off? Thanks.

It's just a theory of mine.If it is set to auto recycle it could be recycling warm moist air round the cabin every chance it gets.Like stop/start traffic pollution or any time it senses dirty air entering the cabin.
I prefer to only put the air recirc on only when i'm stuck behing a particularly smoky old truck or bus.

Cars always steam up on recirculate mode. Not just a Mk7, all of them.

The air becomes too overloaded with the moisture from you breathing.
