Range Rover td6 limp mode?

No oil on any of the joints. Engine side of intercooler and radiator covered in oil just wiped it clean to see if it returns. Variable vanes are free I can move the linkage freely. Is there anyway I can prove it’s working when it should do?

The oil would be the next obvious thing. Proving the turbo won't be easy unless the shaft inside has an enormous amount of play.
The fact you have found oil is the best clue yet.
Any leak or crack in the turbo output to engine side will cause a boost condition. I had an oil film on my intercooler a while back. It turned out to be a hairline crack on a weld. I'd be watching that for recurrence. If there's nothing else in that area that can lose oil, you may be onto an answer.

thanks for the help. Another question i have is I decided to double check the vac lines. On the pressure converter under the inlet manifold a previous owner has blanked the egr port. Just wondering which port is for what? One says vacuum and one port says out. Should the egr blank be on the out or vacuum?

If you look at the solenoid valves in the drawing, they all have the vacuum pipe fitted to the end and the feed pipe to the egr/swirl flaps and turbo fitted closest to the valve body. The pipe should be blocked on the pipe that leads to the egr.
