Om651 what is this part?

[m.p.rogers]

Hi,

Can anyone identify this this part near the oil filter housing, engine is an om651 on a 2014 w204 250 CDi.

Looks to be venting something, anything to be concerned about?

Thanks

Some do vent like that. Nothing to worry about, its just been over filled slightly.
