996 roof rack clips?

[iaiin]

Just had some work done & got back my shiny 1999 carrera 4 & for first time noticed 4 little colour coded flaps on roof? Must be for roof rack? 1 of the flaps has folded down inside a bit, pulled it open with screwdriver, but just falls back in the hole? There seems to be some sort of plastic clip thats broke inside? is this something that can be sorted as everyone i asked, says take it to porsche? bit annoying really , any ideas?
