All cars mist up, except if you leave the AC on all the time, which dehums the air.
Misting up inside the golf is worst for me after I turn the AC off, and is probably associated with residual evaporating moisture being circulated within the car if the AC has just been turned off, and it has been a relatively humid day. The water removed from the air can be carried over from the condensate tray, most will drain away but the tray will still be wet.
I dont feel the need to have the AC on all the time when the external ambient temp is a bit lower, and hopefully saves a bit of fuel.
The worst misting situation is when it is raining and you use the AC to clear then turn it off, you end up in a cycle.
Better off if you dont need AC i.e this time of year, turn it off and use max heat only on the blowers to clear the windscreen, the oldschool way. just manually select the windscreen and set it up to 28 or whatever until it clears
. Leave the AC off after this and it should be a lot better.
The MAX windscreen setting doesnt really help the situation as it puts the AC on and heating, although is useful on frosty mornings due to the electric heater element.
