You may find that return pipe was blocked off by the "Monkeys" at Landrover, It was a change they did on later production
vehicles, Just used a black rubber bung ( no pipe) but they left the hard pipe in behind the engine bay.... My 53 plate is the same.
Thats the pipe i was on about blanking off when the EGR cooler is removed....
Though I did notice there is a pipe fitment on the bottom of the rad belown the boost pipe, which looks like where that blanked pipe could connect. Am I right?

If you have the Rave manual look at the coolant component and flow pages, You will see two of the three options that have been used. On the D2, ( I have not looked into the Def Td5, so maybe that was the same) they also had the third option which had the oil cooler return to the rad blanked off.
So , later rads had the pipe blocked off.

When I removed my EGR, it wasn't the type which had the heat exchanger, but even if it had, following the attached .pdf there would still have been no need to start doing anything to the cooling plumbing.

Well if you are removing the EGR Cooler then you do.

EGR is normally activated at lower RPMs ie low power use and cruising speeds ..the two solenoid valves one works the butterfly in the intake this restricts in coming air so the engine is allowed to pull air from another place ..ie the egr valve ..that has the 2nd solenoid
as for an egr delete I have seen many people just blank off vacuum lines ..but 9 times out of 10 the EGR valve seat does not seat correctly and this case regardless if the vac lines are not connected ..there will be a small amount of egr gasses entering the engine all the way through the RPM range
most EGR valve seats get clogged up over time and loose there seal
as for shutting engine off and over run .the injectors are electronic and when the ignition is switched off the injectors should not be opening

I checked how my 90s EGR and Cooler where blanked off last night, it is how i described in the OP. EGR valve is gone and replaced, cooler is removed and the coolant pipe running from the EGR is also blanked off. Which is the same pipe that runs into the oil cooler on the other side of the engine.
A second coolant pipe just below the expansion bottle, on a T-Piece is also blanked off.
The blank was done by my old indie about 4 years and 25k miles ago, since then the 90 has been totally checked over by LR and Gigglepin neither of which mentioned it as a cause for concern.
The 90 has also run well within correct temps according to the nanocom, never lost any coolant and no leaks either.
The 110 is now blanked off in the same way. Im taking it to Gigglepin on Weds for a 'health check' just to make sure there is nothing wrong that ive missed, i will ask their opinion on it and post it here.

side plate oil coolers work with the flow via the block ..they are bleeding off some water to run the egr
I work on road trains mainly volvo that run a similer set up to the TD5 just in a larger form
and on these bigger side plates there are places where a hoses can go but they are all plugged off

As confirmed by Gigglepin 4x4 today. If removing the EGR Cooler that coolant pipe can be blanked off right at the oil cooler. No need for it once the cooler is removed.

to be honest
if I had a td5 when I was in the UK I would of removed the cooling part
here in Australia I find that extra 1 litre of coolant and the cooler sits right in front of the viscous can only help this poor small engine
