Where does this go?

[kryseric]

I was washing my 2010GSA when a plastic cover dropped to the floor from around
The centre stand.
It has a Part No 35 217 662 212 and appears to be a cover from something but I cannot see where or what it covers.
I took photos :- http://s1143.photobucket.com/user/kryseric/library

Help me out folks - any ideas?

Thanks
Moth
