Anyone notice ”bubbles” sounding from AC?

[Moheisen(FirstEV)]

So, a question for those who’ve had their Cayenne for a while: after every drive, when I put the car in Park, I hear a bubbling/low boiling-water sound coming from the AC. It disappears after a few minutes.

I’ve asked two different Porsche Centers and neither knows what it is, but they say it “shouldn’t” be an issue. I’m not entirely convinced, so I’d feel better knowing if others hear the same thing.

Specifically, it seems to come from the two vents with the emergency triangle button / underneath Sport Chrono.

They all float down ‘ere.

I noticed the same on mine when standing still, when driving I'm driving it's impossible to hear it though..
