OM642 oil leak front of the engine

Hello, I hope you are fine. An oil leak was detected today where the plastic part meets the metal part in the marked part as in the attached photo. Is there an oring / seal that needs to be replaced? If so, I

would appreciate your support for the part number. Many Thanks!

I had the same issue! It ended up being the oil filter housing. Everyone said oil cooler but the independent mercedes mechanic I found figured it out.
