Likely the turbo ****** or the hose ****** is not flat like it should be.

Sure it is not the oil feed line that is leaking? Esp if you reused the gasket.

I dont see how I can get to that back turbo oil feed line without removing a bunch of parts. Do the dealers have some special took or technique to do this job? I have the car for sale and im going to be away for a while so I may pay them to do it.

Most of them follow the shop manual AFAIK, so no special tools for the oil feed line/gasket that I know of.

When I first bought my 2015 (used) I immediately smelled oil and took it back to the dealership, as it was (is) still in warranty. I was told there was a leaking hose on the turbo but that it was part of the assembly, and therefore the whole turbo had to be replaced. Not sure if that helps you, since I didn't see/do the work.

Looks like it could only be one of the two washers or the banjo bolt on the oil feed. If it's leaking from the drain, it has to be the gasket. Worst case maybe the center section somehow developed a crack?

It looks like the number 8 fitting in the diagram. Alldata says .7 hrs labor to replace the line so I may just have the dealer do it. I need a trans issue diagnosed anyway.

It is very hard to get to the rear turbo. There is not much visibility and it's tight between the engine and the cowl. Some of the steps require access from below the car with the sub-frame out. The oil feed line on top of the turbo should have been installed with at least a brand new banjo bolt double washer. If that was not done when the turbo was installed, it could very well be leaking. I think your first step is to determine if the oil is coming from the top of the turbo oil feed or from the bottom drain line.
