Hdi minor oil leak high front of engine, behind throttle body, also causes occasional light burnt oil smell - source?

[Griffy]

looks like a small round component on back of throttle body between body and engine

What exactly is this c 3 cm diameter device - stop valve? - where is the oil coming from - what attention is needed to resolve

thks

The below pic might help you show others where your leak is if you circle the area. Personally I stay away from diesel, just look at the amount of stuff they crammed on it.
(Was about to paste in a petrol with the different spots on the rear, then re read you were diesel, silly me).

..also , just infront of dipstick, mine appears to have a throttle body, so the leak is a few inches in front of dipstick and few inches to right behind what looks like a throttle body - not very photo friendly area, however I can try - how do i upload images plse?
