Hi Jim,

Thanks for the feedback.

Yes, I am familair with the "after-run pump" because I also own a Porsche 9=
51 (944 turbo) and the "after-run pump" operation is very evident (from the=
 fan noise).

I did not experience this after-run fan noise with my S4 prior to blowing a=
 turbo and having them replaced by AoA. Since AoA replaced the originals tu=
rbos with upgraded K03s the fan noise from the after-run pump is VERY evide=
nt.

Personally, I don't believe that the temperature setting for the after-run =
pump was set correctly when my car originally left the factory. Again, the =
fan noise from my S4 after-run pump is very evident now (just like my Porsc=
he) where it was non-existent (IMO) be4.

Stays on VERY long after hard runs and is VERY loud (can hear it from insid=
e my house (windows open) when the car is parked at the curb outside - just=
 like my Porsche).

It is quiet, normally, and you should not really hear it.

Ever since my original K03 turbos and intercoolers were replaced by AoA,
my "after-run pump/fan" has been coming on after a hard run or high
outside temperature.

This NEVER happened with my original K03s. I suspect the dealer put the
correct temperature switch in the engine when they replaced the blown
K03s because many items were replaced along with the turbos &
intercoolers - at no charge to me.

Like I said - prior to this - I NEVER heard the after-run pump/fan, no
matter how hard I ran my S4. The fan/pump is VERY NOTICEABLE now.
