D5 oil misting
 

Hi, I serviced the D5 again yesterday. The last couple of times I've serviced it, I've noticed some slight oil misting around a connection to the air intake? It seems to be focused around this electrical connector or sensor point?
It doesnt seem to be affecting the car at all and I regularly clear it up but it's something I think I should look at resolving.
So I wondered if anyone else has had anything similar or knew how to resolve this?

Ive got a pic here to show the point the oil seems to be misting from. Unfortunately I took the pic after cleaning the area up a bit DOH!

That's not too unusual , if you try pushing and pulling the smaller breather hose can you see any movement around the joints ? Or clean it off with some brake cleaner spray and it will all be bone dry and you will be able to see where it is coming from after a short drive .
