A "turbo timer", as usually defined, is a device which keeps the engine
running for a short period of time (usually on the order of minutes)
after it would normally be shut off, in order to circulate fluids and
cool things down.

What you are describing is a device that sounds similar to Audi's
"afterrun pump".  This is not what I would call a turbo timer, nor, I
suspect, is it what Michael meant because a) the S4 already has one, and
b) if it didn't, it's not the sort of thing that could easily be added.
You need an electric coolant pump, which then needs to be plumbed into
the block, turbos, radiator, etc.  Theoretically you could add one to
a car which didn't come with one, but it'd be very expensive).

You can call your afterrun pump a turbo timer if you like, but it's not
what everyone else means by that term.
