[Vwdiesel] Turbo cooldown

[Erik Lane]

when i had a peugeot 505TD i was also told that i was
supposed to let it idle before shudown. it even has it
in the manual. but it wasn't for temps - it was to let
the turbo spool down so that it wouldn't still be
going 10,000 rpm and have no oil supply to it. also
not supposed to rev them up for the first little bit
to let oil flow get to the turbo.

so i'd imagine that that's more the reason for it. as
far as how long in time, i don't think it has to be
very long unless you've had the engine racing and know
that the turbo is really turning fast. when i was
almost ready to shut down i was never revving the
engine much anyway, so didn't usually do anything out
of the ordinary - a couple seconds maybe. if i'd just
been parking on a hill and had to maneuver the 5 speed
up and down riding the clutch some then i'd let it
settle a bit before shutting down, but still not more
than 15-20 seconds.
