Vito W639 oil leak

[VitoTom]

Hi all. New (to me) 109CDI compact. Leaking oil on the nearside of the engine. I've removed the air-box and set-aside the oil filler in the picture below. I've also cleaned-up a lot of the mess in this area so picture doesn't show the oil that was covering this area.

What have we got on this side of the engine that could be leaking? The photo shows, to the right of the oil filter, a black plastic part attached above a metal part. What are these components please?

Any ideas?

Sorry don't recognise them - sure its the 639?

Yep, it's the 639.
My 2007 109cdi is exactly the same.

The filler cap "A" is for the power steering fluid reservoir "B" & the Power Steering pump is marked "C"
