Default Oil leaking from black plastic square part on oil pan?

My 2000 S80 Turbo has developed an oil leak that appears to be coming from the black plastic square part on the oil pan, what is it?, the oil level sensor?, and is this a common problem and what's the fix?
It feels a little loose and possibly cracked so I'll try tightening it up tomorrow. But what is it? Is there anything else I need to know like o-rings or seals that commonly fail on that part?
Please help!!!

It's on the same side as the oil filter, but behind it, I'd have to check tomorrow about the hoses.

That is the oil cooler that bolts to the back of the oil pan. There is seals between the cooler and oil pan. But they usually do not go bad.
You might have a turbo return line o-ring bad and leaking from bank 1 turbo.

So would I have access to the turbo return line o-ring by removing the oil cooler?
And would the oil cooler seal need to be replaced at that point even if it is not damaged?

Seals for the cooler are about 12.50 a piece.
The seals Tech is referring to is the Turbo drain back tube seals.
Gasket is 3.50 a piece.Seals are 2 bucks a piece.
I would check the turbo drain back tube seals before I would replace any thing.Its a common problem.
