2018 C63 M177 Oil Leak? Anyone knows what's this part?

Hi guys,

I got a 2018 C63 AMG with about 11000 miles. When I inspect the engine bay a couple days ago, I found there is a little bit greasy on this part (Driver Side).






Does anyone know what's is this? I just want to address it before it leads to a big leak.

Another Question on the oil fill location - I notice there is a rubber part around the oil filling location and there is a hole, which I don't believe it leads to the engine. Anyone knows where it goes?




Thanks!

I only see dirt and grime. The line on close-up is a vacuum line.

Thanks. I believe it's not leaking as badly but definitely need to check on this regularly. I actually wipe it before I took the shot, it did cover with a little oil..
