S212 2010 E350 CDI BlueTEC oil leak - please help!

I have a 2010 S212 E350 CDI BlueTEC. My engine management light recently lit amber. Around the same time, the transmission started getting a bit clunky/jerky.

I bought an OBDII reader to use with my phone. It reported the following:

A bit of Googling led me to believe that I needed to replace the manifold pressure sensor so I ordered this:
https://www.amazon.co.uk/gp/product/B01LF7Q64A/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 https://www.amazon.co.uk/gp/product/B01LF7Q64A/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Today I lifted the bonnet to attempt to fit it. On removing the plastic engine cover, I discovered that there appears to be an oil leak per the photos below. Is anyone able to advise me what the source of the leak is?

I did get mine sorted. Google Mercedes black death, and you'll find plenty of info about what this is. Good luck getting it repaired and cleaned up.

Out of curiosity, is that leaking injectors seals?

I thought black death was on the older inline 6 engines (om648 I think). Usually the oil leaking on the OM642s is from the oil cooler, never heard of the black death problem with ours.
