[A4] Turbo cool down time? (was Re: Noob ?s about A4 2.8)

[Tom Reynolds]

Thanks to Brizax, Roger, Brian, and Nick (so far) for the helpful advice
and constructive criticism, I appreciate all the feedback.  All of you
recommended the 1.8 turbo over the 2.8, I believe, and I probably should
have given this as a caveat, but I really don't want a turbo.  Unless...

See, I had a new '85 Dodge Lancer ES 2.2 turbo 5 speed and no one told me,
and I wasn't smart enough at the time (no internet, you know) to know that
you have to let a turbo engine cool down after a "spirited" run - you just
shouldn't shut it off, as it leads to coking and eventual failure, which
the car experienced.  So, I really don't want to buy a used turbo unless:
1)  The modern (in this case the Audi 1.8 turbo) turbos don't _need_ to be
run for a few minutes to "cool down."
2)  The car has had an aftermarket turbo timer (such as HKS) installed and
used by the previous owner(s).
So, what's the list's take on the proper method of turning off a 1.8turbo
that's been driven, shall we say, enthusiastically?
Thanks all,
Best regards,
Tom Reynolds
