In addition to blanking it any good engine mapper can stop the EGR signal being sent to open it and force it to stay closed at any time.

Assuming the egr valve isn't jammed open in the first place which they frequently are.
On a diesel these valves are usually so gummed up by 50k they don't work anyway. If you are lucky the valve is jammed shut and not passing exhaust gases so no need for a egr replacement kit, if you are unlucky the valve is jammed open or partially open in which case the build up of gunge in the inlet manifold continues unabated.
It's definitely worth taking the valve off and having a look at it's condition internally and either cleaning it out or replacing it with new or a byepass kit.
Why this isn't in the lr maintenance schedules is beyond me.

Do these plates completly block off the EGR, or just restrict it, i.e. do they have a little hole in? __________________

The plate blocks the exhaust gas flow completely, no hole.

if you do use the blanking kit then you could always sell the egr valve on ebay, thats if you dont want to put your fullfat back as stock..

Awesome - thanks guys will have a go tonight __________________

Well, have run with the vacuum pipe disconnected for a few weeks, with no discernable difference in performance / behaviour or mpg. So I have put it back on for now, and await a dry day to take the EGR valve off and have a look. .

i'm wondering what the vacuum pipe actually does ..does it keep the valve open or closed?

so if its disconnected ,will the pressure of the exhaust force open the valve..

The egr valve is a spring loaded valve that is normally closed to the exhaust inlet pipe. Application of vacuum opens the valve against the spring pressure.
No vacuum, it should be shut unless it can't seat properly due to gunge.

The pipe needs to be sealed off so that the ECU does not throw up fault codes
