Oil Leak !!

Was cleaning the engine plastics the other day and discovered this leak, the upper leak looks like the breather hose which I've seen a common thing on all diesels but is the lower oil marks which worry me.

Just wondering if anyone knows what this bit is and is this a common thing,

I first thought I dripped some oil when I filled up as its near the oil filler but since I used a funnel I know I didnt, just did not expect a leak on a car thats just done 10K. This is on a 320D LCI

thanks

I assume it's simply dripping down from breather hose- pull it off and check the seal?
I do recognize the copper colored connection below the arrow going into the the EGR valve, but don't recognize the bits below the hose and the "whaler" thing - is that a motorized EGR valve? I have vacuum operated valve there.

regards,

That was my first thought but the oil seems to be comign more from where the whaler bit meets the metal, well its going in to check for flat spot and high beam assistant so will get this looked at as well,

what ever it is at 9months old and 10k should not be happening
