Something odd is afoot in the new Macan.
So, temps outside at the minute don’t warrant A/C so I always switch it off unless it’s hot enough.

Cool air outside (17), cabin a bit warm from the sun, temp set to 20, (cabin must be 24+) yet the HVAC was clearly blowing heated air into the cabin raising the temp even further? I’ve always run my previous cars this way without issue. What usually happens is the outside ambient temp cools the cabin down enough without the need for A/C, but for some reason it’s blasting heated hot air? It doesn’t feel like residual heat as it stays hot. I dropped the window to see if it did eventually cool down to ambient air temp but it kept blowing hot. More so out of the windscreen vents.

Anyone any ideas on this?

My suggestions:

- Leave A/C on all the time.

- Ensure it is left in Auto mode all the time.

- Set the required temperature - don’t fiddle with any other controls!

Yeah it’s a climate control system so designed to be on continually. What Makanik said…

It seems the general logic on this forum is that it’s totally acceptable that the aircon controls on the Macan are purely ornamental. Look at them funny and your windows will mist up or your aircon will toast your knees. Great job Porsche 👍

It's all about the driving. Not fiddling with the controls, especially when you do not need to. Like the Climate Control system.

Sorry I do not think this is specific to the Macan.

Ever since air conditioning became a relatively common fitment, my understanding is that the sensible thing to do is to leave the air conditioning on all the time. the logic being is that if not use seals in the system dry out and ultimately that causes leaks and faults. The advice used to be if you wanted to save fuel and not run the aircon all the timme then at least ensure it was still used regularly say once a fortnight

The controls on the Macan allow occupants to make adjustment to the distribution of air within the cabin and to turn the air con off if outside temps below 3% C, in practice the system does this to protect itself.

Why have a button to turn the A/C off or on if the system doesn’t work properly with it off?
Never had any issues with any other cars including VAG group cars with not running A/C in cooler weather when it’s not needed.
But then again that big panel would look pretty blank without all the nice lights and pointless buttons right??

I’ll ask Porsche when it’s in on Friday for other ‘issues’ and see what they think. You never know there actually may be a fault with it as opposed to me actually pressing the buttons I paid for.

As per my previous post I hadn't used the aircon since I picked the car up in March but put it on last Friday and it was like driving around with an oven door open both on A/C or max A/C. I took it into Porsche Mid Sussex where tech confirmed it was defective.
It is going into my OPC in the morning so I will update when I know.
