So I started mantenance work on my s212 e220 bluetec 4matic 2015 with all oils and filters.
What I found were several oily locations.
Please help me pinpoint what could be the cause.
One leak is minor on the right front side of the vehicle under the cooler
One minor leak on the side of front differential
One large above the transmission. Several drips over night with engine off. Initially I thought it's the sump seal but the oil stain goes up a long way.
Leaks usually travel down. Try to start visual inspection from the top as much as possible... its not easy.
While you repair this oil leak near firewall also replace coolant elbow pipe at firewall.
Thank you CaliBenzDriver!
It is definitely engine oil. I now completed changing all oils and after starting the engine, this spot next to auxiliary transmission pump started dripping. After half an hour there was already a small puddle on the floor.
I managed to film it with engine running: https://youtube.com/watch/9dR2Iu9aN4w
I also made some pictures from above the engine and there are clear traces of oil right in front of the firewall.

As far engine oil, sources that are back there are plastic cam caps and PCV plastic Cover.
The V engine valley also feature a drip hole that dumps on driver side.

Thank you. But is this relevant to om641 engine = 4 cylinder diesel?
Yesterday I tried locating those cam caps but could not find one. Can you assist? I saw some videos on V6 engine and I don't think location is the same.

Good catch: L4 has a single bank. I don't have one to compare what's on the rear side.
Try posting over in the diesel section. Or atleast looking around over there. This section they all assume you have gasser and generally give input accordingly. The w212 section is good for all the other stuff just not diesel specific.
