While driving if you undo your seatbelt you don't see "Fasten Seatbelt"?

Then barring having a bad sensor for the seatbelt it sounds like your cluster is not working.

A read of codes is necessary but pretty sure you will also be doing some work on your dash cluster besides whatever is causing you to go into limp mode (not DME )

It doesn't soundike you are describing limp mode. You are describing lack of power. Somebody else with a diesel had similar problems recently but I can't remember the resolution but I think was either the high pressure fuel pump or turbo.

The car ran ok at low RPM or low torque demand but on hills it couldn't supply the torque demanded of it.

Limp mode doesnt come and go. Once triggered usually stays until you reset with a scanner. (but can reset after a cool down and restart). Also no chance no code + limp mode.

Intermittent problem just makes it harder to find . Can you get it to reproduce on demand?

Quite possibly yes.... This "box" is a vacuum reservoir and supplies vacuum to the turbo boost control. You need it. I'll bet that when/if you read the codes from the DDE (no DME guys..) you have codes for your boost control.

First thing I'd do is get a new vacuum reservoir and fit it.... It obviously failed and somebody decided it was cheaper to bypass it than replace it - which is true but that doesn't make it a good idea!

Do you have "second level" scanner to read more than basic obd codes ?
