After the latest software update, I set my Macan 4EV to charge overnight, in my garage, for an 8 A.M. departure. Got up around 6am and heard the Macan engine running (sounds like climate control engine revving) but I could not turn it off. I tried everything but it ran until 8am. I only reached 287 SOC at 95%. Not sure what to think of this. Will try again before my return trip. Thanks, appreciate any feedback.

cooling for the battery while charging - it’s the fans to cool the battery

there is no engin to run while the car is stationary

Not sure what you are referring to, but if you mean that you could hear some kind of “fan” from the outside of the car running at high frequency, that’s just the car cooling down the battery, especially if it is in warm weather.

That makes sense, I live in the desert, so the garage could heat to 120*. I'd not thought of it but I'll try again, thank you,

but if the fans are running all night while charging it will take a long time to finish the charge and it will not charge to capacity, right?

it’s fine the fans don’t use that much power

Normal for hot garage charging.
Target charging does not go miles 287/360 (that is a wild guess), it goes by SoC in %, so if you set it to 85% then it will reach it by the departure time assuming you plug it in to allow enough time to reach that target. As soon as the charging starts, you can see in the App when it will reach target charge.

yes, but I could only get to SOC 287 rather than 360+
the SOC is a guess and easily mislead - experienced EV owners ignore it

my Porsche 911 GT3 after a whole day on the track thinks I can only drive 107 miles on a full tank of gas - and it would be right if I was driving on track al the way home.

the SOC milage estimate is called the "guess-o-meter" and it's not to be relied upon - the only accurate measure of battery capacity is the % SOC…

the guess-o-meter is easily lead astray by recent driving consumption and has no idea what is going to happen in front of it…

if you want an accurate estimate of how far you can drive put your destination in to the PCM navigation and check the battery % at your destination…navigation knows about speed limits and elevation changes and likely consumption generating a much much more accurate estimate…

the SOC milage is simply a random number generator to be ignored when ever possible…

Ok, only got to 94%. Fans draw electricity to run. Thank you

Thanks I need more experience with the PCM. I’ll make it a point to do that. Really good advice. Thank you so much.
