Weird sound when shutting down engine.

Before when I shut the engine off there was this weird sound. Sounded like a gurgling or rumbling sound.
Is it normal?

I'll see if I can duplicate it again.

I hear this wonderful turbine slow down like sound just after I switch off my car. I always stay and listen to it, even though it is fairly muted.

I'll try to listen to it more closely tomorrow to see if it's what you're describing.

I know exactly what you are talking about. My wife starts bitchin everytime it does it. It does it when you turn it off or when you hit the clutch on first gear.

and yes, I also hear that sweet turbine slow down like sound just after I switch off my car sometimes.
