All I know is that the valve and piping went from where the blanking plate is on the exhaust manifold to a tee on the hose between the IC and inlet manifold.

There was a throttle position sensor on the IP and (I just read the manual ) a control box under the cubby box, a vacuum valve on the firewall and it looks like the EGR valve was mounted straight on the exhaust manifold.

Some Tdi Defenders even had a cat in the exhaust, so we got off lightly here.

Sounds a lot like it is just down on boost.
Couldn't be as simple as a sticking wastegate?

Just a thought, I remember reading ages ago that the defender lift pumps had a gauze filter screen under the cap at the top of the pump and can get blocked occasionally. Is this correct? Could this be an issue? My 300tdi disco doesn't have this, as from what I read, the defender had these because they are the type of vehicle that drives to areas with suspect fuel. Correct me if I'm wrong.

OEM ones don't, it's the same pump as the Disco, some aftermarket (Delphi for one) do.
