A it of an update and a question for you:
The vehicle is almost ready to be picked up. The HG issue turned out to be more than one coolant leak (x3 HG tests were done and no compression gases were found in the coolant). The EGR cooler is fixed and the wheel bearing is fixed (and front disks and pads have been replaced also).
They are looking at the 'oil on turbo' issue this afternoon.
I am taking care of the small stuff (blankets, tow eye cover, gearbox guard, etc) and the only item of contention is the 'rear prop - carrier bearing mounting collapsed'. The garage carrying out the repairs are saying this does not warrant replacing the rear prop and that there is nothing detrimental in leaving it as it is (they said it is nothing more than a doughnut shaped piece of rubber, has nothing to do with the MOT and if the prop was faulty I would be getting some sign of this in the form of vibration.
To be honest there is no indication in the form of niose or vibration to draw my attention to anything. Should i let it go?
Can anybody else share the benefit of their experience please? I don't wan't to get stuffed when the prop goes bang in the future but I don't want to be pedantic either if it really is nothing.

I think the rear prop carrier bearing was found to have some play in when it took it to LRS too!
They didn't seemed concerned about it, but did say it would require a whole new prop shaft
...but glad to see your getting things sorted!

Update:
The car has been back to MMC because the coolant system continued to pressurise. Their LR garage did x2 compression gas tests and they were adamant there was no HG issue.
I picked up the vehicle on Saturday and........ within 5 miles the 'Coolant Level Low' message was back and there was a jacuzzi going on in my header tank (that they had replaced as part of the repair due to the shot bleed screw). I took it straight back to MMC and they just put their hands up and said 'please take it to your indie, get them to repair it and we will pick up the bill'. I think they have lost all faith in their own LR repairer at this point.
Anyway, took it back to LRS engineering and they did some tests. Now just waiting for their email with the news. It doesn't look good though

If the EGR valves are blanked/removed, the EGR coolers are still 'in use' although not actually cooling anything. There have been instances where they have corroded on the inside leading to a loss of coolant with no visible signs. They can however be bypassed with a suitable piece of tubing.
I'm not sure but if they leak inside would that not produce pressure in the system as they leak into the exhaust? I'm sure someone way more clever than me will be able to say whether that is the case or not. You guys are gonna be busier than a test bench in a plunger factory!

Cheers Ed and thanks for your advice Blue.
LRS have given their verdict - the smoke test was positive for diesel combustion gases. The cooling system is (and should be) a sealed system that is under pressure from the expansion of heated coolant. However, that system is over-pressurising massively and what could be the most likely source of that pressure? The combustion chamber.
This is all bad enough but they also said the brass in the HG is still very shiny and the head is very clean. Which in their opinion looks like the head has been off fairly recently, which in turn could possibly mean a crack in the block.
Either way it is all very bad. I have forwarded the quote for the work to MMC Car Sales. I haven't heard back from them yet so I really still don't know what my chances of a happy ending are

Will they not refund you for the car so you can buy another one? You guys are gonna be busier than a test bench in a plunger factory!

I haven't had a response yet but when I do I'm sure hoping that's one of my given options.

Just had a conversation with MMC. They want one last crack at fixing it now that LRS have just quoted them £2.2k to change the HG!!!
MMC's repairer is sure it isn't the HG but more likely to be the EGR coolers leaking and pressurising the system (just as Blue alluded to in his post above!) LRS have said this is plausible but in 12 years they have never heard of it happening with either a LR or RR, only in a Transit!
Is it possible? Can anyone offer their advice or confirmation please?

Just a thought though Blue - my EGR's are not yet blanked. Could your theory still apply?

Well, I guess the collective knowledge of even this great place has its limitations. I'll let you know how I get on.
Cheers,

She's baaaaaack!
Bushes and a few other bits and pieces also done whilst the body was off (all at MMC's expense). They even delivered the car back to our holiday campsite in Norfolk and picked up their courtesy car (I will miss the oomph of the Audi S-Line though).
So far it looks like a happy ending is on the cards.
Thanks to those that showed concern and offered advice. 
Cheers,
Darren
