It's still good practice to give it at least 60 seconds at idle though. I tend crawl up the last 100 yards of the lane leading to my house on idle in 2nd gear, then drop to idle in 1st to enter the drive. Does for me.
not sure are are correct no dosh.
the garratt turbo has a life span of around 75,000 miles, and the 2.4
jtd's do seem to suffer turbo failure, sooner or later.
as for boost pressure, well turbodiesels run at a fair good boost and
although the diesel engine runs at a lower speed, the turbo does not.
on the AROC website, turbo failure has been as low as 30,000 miles,
