"Thump" sound when closing door

[desere]

Hi, as I close the driver's door and hear a rattling \ tapping from behind around the rear tire. I found a topic in which they describe that some ventilation caps open/close and that's where the pressure noise comes from. For me, too, things look as described in the topic, but apparently my cap is very loose, because sometimes I can hear it in motion when everything is closed. Or maybe it's broken because the car had an impact in that area. The noise is not from the undercarriage.

My question is does anyone know exactly where these vents are, how I can get to them and if there is a picture. I want to repair them, because I don't like the rattling in motion.

if you have boroscope camera it may be possible to look in that area without bumper removal.

And yes, if there is ussue with the flaps its only
by dmg in that area. Otherwise there is nothing to maintain on them. they just work and are pretty much stuck there.
look underneath the car.

If there was dmg to the flaps usually there is also dmg to the metal bumper absorbers from angled rear impact. Thats indicator. Not saying you have dmg, just giving you more details.

The flaps open briefly to let air out when you close doors and then self close.

It's interesting how different this is to my MX-5. There is nothing like this on that car, so the windows actually retract a little when you open the doors so that they can close properly. They are supposed to go back up, but I regularly have to blip the button to top them off, so it isn't perfect.

This is common on many vehicles.. my G35x and GX 460 have those in similar area
