Correct, it will temporarily stay open for cool down purposes when needed even after you shut off the Macan... when driving it will vary.

Porsche Macan S - Efficiency-enhancing measures - Porsche AG

"Active aerodynamics
The radiator grille shutter opens the cooling air flaps only as needed. Whenever the cooling requirement is low, such as on relaxed drives, the radiator grille shutter closes. Aerodynamics are improved, which helps to improve fuel economy. If, for example, a sporty driving style is adopted and the demand for power increases, the cooling air flaps will open and let in the necessary amount of cooling air for increased driving performance."​

Where are these flaps that one can see them and know if they are open or closed?
Look straight into the grill. Flaps open, you'll see the radiator; flaps closed you won't.

In these day here is very very hot...38° Celsius.

My Macan S petrol is always grill radiator opened and the front fan are always turned on after I turn off the car... To take inside a bit of air for cooling engine.

Is it ok?

I remember that my previous cars do that only few times after I go fast on street... Now my Macan S do that also when I go for few few km...

So after turn off and lock the car at high temperature I note that front grill is opened and the fan are working for cooling, and the vent

It's normal, plus the fan you might be hearing is from the AC and not the engine one.

What do you mean - very hot at 35 deg C? We just hit 40 deg C in Prague today and should be hotter still tomorrow. Can I come down to Rome to cool off?

40s? What a difference just one month can bring? It was 16-17 deg C when we were there in late June - and it was raining too -

There is somewhere on E551 - east of Ceske Budejovice

Mine is always shut after turning off the engine, in any weather.

I've noticed mine open on occasion and closed on others, but never really paid attention to the weather to see if there is a correlation. I assumed that it was related to the engine temp at the time of shut down.

It's been parked for about three hours, but the radiator grille shutter stays open. The ambient temp is like 42F (5C)degrees. I've never seen it stay open like this.
So, do you know whether the louvers shut as soon as you started the car? Just wondering if they simply keep their last position until the engine is restarted.

I watched mine last night after I switched off the engine - the fans kept going for a couple of minutes and then switched off after which the shutters closed...
