Evening all.
When I have the climate control switched off, really hot air seeps into the cabin from the two face level vents on either side (not the centre two). Closing the vents helps but it still seems to come in. It doesn't always do it but often enough. At times I've had to put the aircon on to stop it even with the sunroof open!
I've read about the HVAC system reset which I'll try next time I'm out in the car, but has anyone else noticed this and will a reset of the flaps fix it?
:smiley:

Nothing to lose by trying a reset.
Got access to VCDS??, could point to a motor, which actuates the flaps, problem.
Could be the motor packed up, or actuating arm come adrift, stripped teeth on actuating gear??

Thanks madstaff. Unfortunately not but I could always get a garage to have a look. It's been doing it for a very long time but I keep forgetting about it! I suspect it's not a motor fault as once switched on it all works well. It seems to me as if the flaps that should close to stop the hot air out when it's switched off are settling in the wrong position. Will keep my fingers crossed that a reset sorts it.

Thanks for that, seems just too easy... Fingers crossed!
-
Oh well, the recalibration did it's thing but hasn't made any difference. I'll just have to go with the simple approach and close the vents...

I find a bit of warm gets through mine even with the heating off as well.
However if you turn the heater on, set the temperature lower and then put it back off the air coming through is cooler.

Thanks, I'll try that.

Why are you turning it off anyway?
-
Same thought, always leave air con on.
-
Aircon uses more fuel. I know they are a lot better than they used to be but it is still load on the engine.
However I did read that if you do 60mph or more and have the window open it uses more fuel through drag than by using the aircon.
If you are using the car in town it will make a difference.

It goes off when I have the roof and windows open. Although the days of enjoying the wind in my hair are long gone, I love having the roof open and do so as often as I can.
It wasn't doing it today so perhaps there's something in the temperature that was set when it was switched off.
-
Also noticed this happening earlier in the year and wondered why the car was getting so hot inside with HVAC off.
As mentioned above turning the temp to min before turning off seems to work for me to. I haven't found any other solutions, only comments that it's just a thing that this car does. Bit naff really isn't it, never had this issue with older and less premium brands of car.

Not saying it's the case for people on this forum, but the answer to that question is generally that they don't understand properly how it works.

I've addressed this already. Or perhaps you think I should have the aircon on with the windows and sunroof open?

You could spin this around and ask why are people leaving it on when it isn't needed, as doing so uses more fuel.
The fan also makes some noise, especially on 2 bars or above.

it doesn't use that much fuel really, I've never noticed any discernable difference in mpg. You maybe need to have the system checked if your fan is making a noise. You cause more issues by not using the climate control. Seals etc being one.

It’s not used just for its cooling properties - it also dehumidifies the air, so can be useful at this time of year when condensation on the inside of windows seems to be an issue in some cars.
I keep mine on 24/7 for the cooling effect in the warmer months and the dehumidifying effect in the colder months.

The gas is also a lubricant, maintains seals etc. - mine is constantly on. If you flick through the Car menu you can see how much fuel is being used by convenience consumers - it’s 3/5ths of FA for the climate control.

Yes I understand the pump is variable compression. During the 40 deg C days, the consumer menu showed a/c was heavy on power, unsurprisingly. But now it is cooler, it uses virtually nothing.

When I give mine a bit of a blast it does the same. Also, I cannot modulate my temp very well. 23 degrees is way too cold and 24 degrees is way too hot. Aircon is working fine though.
