My 2019 (mfr April 2020) Octavia III (Scout, 2.0 DGS-7), recently I think (because I don't use A/C recirculate often, but it's been brutally hot here in Spain lately) when the A/C is on, the cabin temperature has already reached the desired set point (e.g. 24°C), *and I have recirculate set on* (e.g. I'm driving through a tunnel and I don't want outside air), seems to blow slightly warm-ish air. If I switch off recirculate it immediately cools adequately.

I hadn't noticed this during the previous four years since I bought the car new.

Have you encountered this, that on recirculate when the cabin temperature is already cooled adequately to the set point, that it will a bit too aggressively avoid blowing even colder air into the cabin, but with recirculate off/ taking in (much hotter) outside air, it will cool just fine?

(I'm asking in part because I noticed this, and in part because the last time I had my car in the Skoda shop for an unrelated minor bit of maintenance, they told me that they had done a small repair on the A/C under extended warranty).

thanks,

 

24*oC is damn hot air and a interior temp for a car is it not?  (even in hot countries.)

 

24*oC outside (ambient) and i have the setting for a cars interior at 16*oC.

*grin* I guess I'm "friolero" (Spanish: sensitive to being too cold). Well, not really; but depending on whether the outside air temperature (which was around 35°C) is accompanied by direct Mediterranean sun, or if I'm in shadow at the time, I'll keep the cabin temperature set to cool to anything between 23° and 25°, and that's quite enough for me. I tend to dress lightly, and to some degree the already very large difference between outside and inside temperatures I guess is enough for me.

I haven't tested how recirculate mode treats the cabin at far lower temperature setpoints.

The weather here (UK) might be in the 20's *oC and the vehicle in the sun and the interior reaches the 40*oC.

 

You are dealing with a Skoda and so so AC system.

 

Bringing the temp 10*oC lower from 26*oC inside to 16*oC can be very dependent on the ambient temp.

36*oC to 26*oC as well. 

 

 

All true, but I'm not sure how it relates to my specific question, which is that when recirculate is on, the system seems to choose to supply just slightly warmer air than it supplies when recirculate is off, something that I hadn't happened to have noticed before, and I wonder whether it suggests that something might be failing.

It is a pretty basic set up. 2020 car with technology from a few years before.

 

Something might be failing.   

?

What was the small repair?  They have done under Warranty.  What parts were replaced or not replaced?

 

4 year old car built 5 years ago.

Was it even sitting a while built before it went on the road?

When I noticed this effect, I'd been driving for 100km or so, and the A/C had done a fine job of maintaining the cabin temperature except for the few occasions throughout the length of the drive when I'd switched on recirculate mode (due to being in a tunnel, or following a smoke-belching car or small motorcycle). And even on recirculate, it's not that the cabin got hotter and hotter and hotter; I just fairly quickly noticed the difference. (What I should have done was dropped the temperature several degrees in the moment, with recirculate still on, to see if the A/C resumed effectively cooling; but exactly these moments were times of traffic or road complexity and I was otherwise occupied).

 

I had just earlier today sent a request to the shop for more details about the A/C repair; Spain is a place where work orders do not tend to be very detailed unless/until you demand it 🙄. Waiting for their answer.

My theory would be that the climate control tries to adjust the output air temp due to the incoming (recirc) air being colder than what is being drawn in from outside. Does it feel the same when you adjust the temp up a degree or so? Does it settle after a little bit?

 

24 degrees is mind boggling, I had the climate control set to 16 degrees when we were in Lanzarote in a very nice 22 plate Seat Arona of all hire cars!

 

That theory makes sense. I think I did try lowering the temperature by one degree and the system began to cool again. I was in traffic and couldn't focus on the experiment at the time. 

I'm away in (mostly!) cooler climes until October, but when I'm back I'll see if I can test it again on a nice sunny Mediterranean day!
