Bought a used 06 Coupe, and I found this plastic piece in the glove box. It didn't really look like it was broken off of anything, and I can't recall seeing it in any pictures on this site.

The third pic shows some writing on the underside. It says 8 >ABS< , then has a Mercedes symbol, and underneath that it has what I believe is a European phone number, 202 919 04 20, but I'm not sure.

Any ideas what this part does or where it belongs?

Thanks.
