I believe it is a holder/clip for the air vents I had one fall out from that area when I had my dash out I proceeded and threw it in the spares bin!!!!!!!
It it easy to get to, to refit or not worth the hassle?
I did the o rings a few weeks back mabey I disterbed it then when I was trying to get the air pipe out
that said im going back in,in a few weeks to do the blend motor so will have a look at refiting it then
