Hi
1) On cars with climate control, I have always left the a/c on throughout the year. I understand that modern variable pumps don't take much energy when not working hard to cool, plus it has advantages regarding demisting, fresher feeling air, temperature management, dehumidifying the air, and keeping the seals lubricated.
Do you all leave yours on all the time, or turn it off when not actively needed? Does anyone set it to eco mode in the winter (via the profile menu)?
2) Despite this, today I turned A/C off, as I had my 40 mile journey to work with 35 miles left in the tank, and every little helps. (I made it, and 53 L went into the 50 L tank on arrival - and I got 51 MPG on the journey. Yes it's a GTi!). I was interested to see on the Comfort Consumers page of the CAR menu that even when the a/c is off, there is still a small amount of energy use. Much lower than when A/C is on, but still a residual amount. Is this because the A/C is so useful it never really switches 'off'?

I'm sure I've seen mine disappear from the Consumers screen, but maybe I'm mistaken. I'll try it out later
-
I leave mine always on as ensures the windows always stay clear but do turn the whole system off now and again as I like to get some fresh air when I can. That's the time I miss having a sunroof!
-
As above, on all the time, occasionally turn off when windows open (as per the very warm day on Saturday) for a bit of fresh air.
-
My air con is on all the time as well.
-
Just checked. If I turn it off, it disappears from the Comfort Consumers screen almost immediately.
-
On all the time for me. I see far too many people who rarely use it to save fuel, but then fork out for aircon regas because the seals have dried out.
Also annoys me seeing cars fully steamed up on busy motorways in Autumn/ winter which the AC would sort out.
-
The consumers screen doesn't show you that having the AC off and the window open probably does more for fuel consumption by increasing drag, particularly over a few mph...
-
On all the time, on my mk6 the aircon pump had a clutch so it freewheeled when not on, maybe the same on mk7?
-
On all the time for the whole year.
-
The Mk5/6 pumps run all the time, so mine is off unless cooling
-

Think that only happens if you turn the whole climate system off. If I just switch AC off then it still appears as using a bit of consumption.

like I said my 6 had a clutch on my pump (it fell off so we had to get another pump) and the mechanic fitting it told me the pumps only ran when switched on

Yep as above, mine is on all the time. Can't see any reason to turn it off.

Ohhhh, I misunderstood the question. I forget that you can have blowers, but not A/C. Always wondered what the point was. In that case, mine is on all the time.
-
maybe the comfort consumers counts the air blower under the a/c label.
My a/c is always on, it dehumidifies rapidly in the winter weather and cools in the summer.
