Golf 6 aircon and air recirculation

[OrbitalDawn]

Every time I start the car the aircon and air recirculation is switched on automatically. If I turn them off and restart the car, they're on again. Can't figure out if it's supposed to be like this, or if there's something wrong. Can one turn this off?

Check that you don't have the air output set for demisting.

Yeah, first thing I did. It's not on that.

Don't hold me to this - it's been a long, long time since I had anything to do with VW climate controls - but I believe it's meant to be that way. If I recall correctly the aircon will default to being switched on, but the recirculate function is dependent on the differential between ambient and interior temperature. If it's colder inside than out it will switch on recirculation to speed up heating and conversely not if it isn't.

It might be something that can be toggled via diagnostic computers.

Mine doesn't do that and neither my colleague's

The top is semi-automatic Climatic aircon, the bottom is fully automatic Climatronic climate control. Again, if I recall, it's the climate control specifically that functions like this.

First one

I also have the semi-automatic climatic aircon, not full climate control. Guess I should just take it to the dealership so they can have a look. Maybe it is just a diagnostic setting.

Do you start your car in reverse gear?

Nope. I know the recirculation is put on automatically when in reverse, to stop exhaust fumes from entering the cabin, but it happens while in first or neutral, as well.

I've seen it go into recirc automatically when there's a big difference between the inside and outside temps, or the requested and inside temps.

Yeah, it's to speed up the heating/cooling, as Haptic said. But this happened in very mild conditions. And there's no 'auto' function that controls this stuff. It just does it by default, which is annoying.
