2013 E350 OM642 Front Oil Leak
Hello everyone, I would like to seek your advice/collective wisdom. 2013 E350 BlueTec OM642, 126K miles, owned since new, immaculately maintained. AEM done in Sep '22 at 114K miles. Brought it for service last week, discovered an oil leak. Unidentified source so far. Only on the front of the engine, in the splash guard (but no puddling). Engine oil level did not drop, no puddles/drops under the car ever. Most of the visible oil was on the sway bar, relatively equally distributed between the driver and passenger sides, and on the hoses above it, bot no overspray on any parts behind it (see a few screenshots from the video walk through from the dealer; circled in red is one possible source - not sure what the part is, and not sure whether I am correct about it). The belt itself looked clean or at least clean enough.
Completely cleaned/de-greased the engine, tech told to drive for a few days/about 1K and come back. Drove about 200 miles so far, at varying speeds, tried to examine the engine from above, did not find anything obvious. Filter housing is dry, anything I can see with a good flash light below it is clean as well, splash guards appear to be clean.
Have any of you experienced similar leaks (I have looked carefully here and on other sites, but have not found an answer). Any thoughts/advice on how to proceed? Love this car dearly! Thank you everyone.

When it comes to German technology it means realms of possibilities. I keep my engine super clean from top to bottom. Start with cleaning the engine. If you have a turbo then check ducts as oil from PCV system can escape.

Not super helpful but our 2011 was the oil filter housing. As noted, start at the top of the engine and then inspect going down to see where it starts to get oily. The oil filter housing got oil everywhere since it ended up on the belt and flung around the front of the engine.

Im not familiar with that engine so had to look where the oil filter housing is. If it was leaking it looks like you would see oil running down the power steering pump and ac, which seems to match up with your photos on the bottom.
My M272 engine had oil seeping out from the oil filter housing so I replaced both gaskets and it fixed the issue. The car had just hit 150,000 miles so I had to replace the coolant anyways so I crossed that off the list at the same time.
I was looking around for your oil filter housing and see its also made of metal like mine is. I found some gaskets that im thinking will fit your housing.
