I'm getting my engine bay cleaned soon and thought I would take a few "before" photos. I noticed something greasy and figured I would check in with the community to see if it's anything I should have looked at further.

Photo 1: B58 stock photo to show the area in question. Does anyone know what this hose line is for?

Photos 2 and 3: Photos of my (dirty) engine bay in the same area showing the greasy area that I referred to. Looks like it could just be grease rather than a leak of some sort? That's what I'm trying to figure out.

There should be nothing there. It's the airbox 'muffler' to reduce intake noise. Shouldn't have grease or oil in there...

Strange indeed then. I'll ask service to take a look at it, which will be soon as I have a different issue for them to correct as well.

It was probably greased when installing at factory. Just the little o rings. There's no oil in that area. Basically the great residue attracted dust/dirt. Wipe off and you're good to go. Will literally not cause an issue unless you don't put it back together correctly and have an air leak.
