Default gear shift park turns off engine s5 sportback

I am completely at a loss to explain this, which started the other night.
if i stop the car put the gearshift in park the engine stops. (well almost always because sometimes it continues to idle.)
if i use the "tab" to engage the electro mechanical brake and leave the car in neutral the engine continues to idle.
is this a "feature" or a software glitch?
i have about 1200 miles on the car, which i really love. Traded in an A7. Loved that one too. but the s5 handles better.

I called my dealer Mohegan Lake Motors --a great dealership, btw--and they are flummoxed.

Is your Air Conditioning in Eco mode? If so it may be that the engine is shutting down due to Start Stop being active and no need to cool the cabin.

If the cabin is still too hot, the engine will run to power the AC.

It's just a feature of the Stop/Start system. If you are in traffic and not going to move for a while you can just hit the park button (differential will lock) and take your foot off of the brake without the engine being restarted. Depending on conditions (AC / engine temp / other stuff) it won't always shut off the engine.

Are you saying your car shut off when put in park even with the auto start stop disable?

yes. when auto stop/start is active (the default) the engine will be cut off UNLESS you LIGHTLY press on the gas pedal. this i just learned from reading the on-line manual.

if you fully depress the gas pedal the auto stop/start functions and the engine will cut off.

pressure on the gas pedal is what governs the stop/start function (if you haven't deactivated it).

Can't figure out the logic of this. but i accept it.

Any further thoughts??
i'll make sure that the stop/start is deactivated from the dashboard button every time i get into the car.

My ritual is:

1.) Start the car
2.) Immediately press the start stop button to disable it!

Biggest PITA so far

We don't have our Audi yet since it's a 2019, but when we did the 24 hour test drive with a 2018 this is the first thing we did. The start/stop is too annoying to tolerate.
