What’s this bolt near gearbox sump that I just tightened (pic included)

Hi I was under my 2008 e92 320d. And I noticed this little torque bolt near the oil sump (pic attached). It had a drip of oil around it so I got a bit worried and tightened it up because it was a bit loose.
Was it meant to be loose?
Should it have a bit of drip

That's a bellhousing-to-oil-pan bolt. It is not a source of oil leakage. The oil you saw came from the oil pan gasket.

No bolt is meant to be loose, especially that one.

And of course there should be no oil leak anywhere.

Clean up the area thoroughly and check again in a day. This could be from a leaking oil pan or coming down from valve cover.

Shit I’ve already tightened it, is that bad? What’s gonna happen?

If it was loose, then it's ok that you tightened it.

Might want to check the rest of the bellhousing bolts too. But the oil came from above, not from that bolt.
