High pitched sound coming from doors when opening

Just curious if anyone else has run into this issue with their GTIs and if there is a fix that you know of.

When all of the doors are closed and I open a door, a sound comes from the door as if air was being pushed through a small opening. However, if another door is already open, it does not make the sound. I've checked and all windows are closed all the way and the car is off.

Already took it to a dealership and they could not figure it out.

Oil your door hinges if you haven't already. My 2011 hinges creaked until I used some hinge oil.

That is caused by the air in the car being sealed so well, that’s why it doesn’t do it with another door or the window open, there is some sort of vent with a rubber flap over it hidden behind the sides of the rear bumper just behind the wheel arches, when you open the door this flap is sucked tight against the vent causing the noise,

This is on a MK4 but you get the idea!
