odd noise when turning off

[capt kirk]

Hi gang
Ive noticed recently when turning off the engine i get a sort of fluttering noise that seems random, sometimes it does it sometimes it dosnt. I tend to think its the turbo running down but not sure. Any ideas....

Cheers

N75 vacuum valve or Moo Valve? Related to the Turbo Actuator I believe.
Make sure the vacuum tubes to the valve are tight fitting.

It’s prolly what WG said but, does the engine stop abruptly as it should or does it stutter then stop?

Could be the anti-shudder valve , very similar control lop to the N75.

Engine runs fine. No loss of power. Turn off and engine runs down normally and just as it stops you occasionally get a whirring noise with a sort off flutter and then it stops normally, spooky. I did think it may be a turbo bearing but surely that would be all the time so maybe not. Could be the moo valve so im gonna take a look in the morning.

The pipes were redesigned to prevent this.

I believe the Update for the pipes was prior to the T6 but that doesn't rule out the pipes.
