Guess the part?

[Stuart02]

Everyone's favourite game. Would anyone care to guess what these belong to? Or even what it does? A locator/guide of some sort?
And, is it as broken as it looks?
Possible P/N ZnA14Cu1, and there's a 4 in the hollow side...
Found them under the middle row seats, but they seem to be working fine.
There does seem to be a loud rattle somewhere in the sunroof, perhaps?!
2010 HSE...
Thank you!!

Zn is zinc
Al is aluminium
Cu is copper

That's the composition of the part.

Oh, baha, yes!
But why is there an alloy recipe on a loose bit in my car?!!

The EU may demand that all parts can be identified for recycling?

I can't find that part in the parts catalogue pix of the sunroof

I can't find the sunroof in the parts catalogue to look for that part.

Thanks for looking!

As noted the markings are not a part number but the metal composition.

I'd say (maybe somewhat obviously) that it is part of a larger component rather than it being its own individual component.

Doesnt look familiar but the material does.
Door handle parts is one...

P.S have a look under the second row seats, I remember vaguely something used to break when customers forced the seat to fold when they jammed.

I found one of them floating around in the back of mine too! My thoughts were something to do with the rear seat mechanism. Everything still works, and has for the last 4ish years since i found it so I'm not too fussed.

A spring loaded catch from somewhere. It looks like two locating prongs have snapped off.

I've looked through the diagrams of the seats and locks but can't find it.
