Oil leak from rear of engine (where from?)

[Argos69]

Hi folks,

I've still not got round to the timing belt job, but noticed an oil leak I'd like to identify (and fix!). However, having looked from as many angles as the cold weather and a pair of "wish they were taller" drive on ramps will allow, I'm struggling to know what I'm looking at.

I've removed the plastic under tray, which was covered in engine oil and cleaned off as much oil from the engine and ancillaries as I can. I left it a few days and a few drips have arrived on the drive and more appeared on the bottom of a plastic pipe under the rear of the engine.

I was always told that you should try to find the highest oily place on an engine and that this would likely be the cause. The highest place I can really see anything oily is by looking down the back of the engine with a torch, from the top on the passenger side. A black plastic tube and bracket "seem" to fit the bill. But (!) I don't really know what I'm looking at. Is this some turbo air pipework? Is there any kind of oil trap or filter here that might need changed?

I took the attached photo with a phone and torch, so it's far from perfectly framed, I'm afraid.

As with all the problems I bring to our forum, I'd love some advice and opinions as to what is wrong.
(it's a 2.2Hdi engine in a 2013 Tourer Automatic)

Thanks in advance for any help!!!

I would give it a good wash off and see where it starts from, I usually use brake cleaner aerosol to remove external oil park it over a sheet of cardboard afterwards and you might get a direction from where it drips
