To clarify, I am 99% certain in saying that pre facelift 2011my UK Td4 did NOT have a water cooled turbo; facelift MY 2011 TD4 cars which appeared mid year 2010 were fitted with the water cooled larger turbo.
.
The later TD4 and SD4 mechanical builds are the same, it's only on the auto that the higher output software was available hence SD 4; one assumes that LR would be cautious of warranty claims on the manual cars for the known clutch/flywheel weakness; hence not offering the higher output for a manual box; in fact they lowered the power from 158 down to 150

Kind regards from Fred.

Cool Fred it's just that I was advised from a very good source this was the case.
There's a huge explanation for this bit I won't go into this here!
