Pretty sure it's from the turbo plumbing. |

Just had a turbo actuator changed on mine and the noise appears to have stopped. Apparently the original units corrode and start sticking. The new unit has a different design to prevent this. |

Just done a 200 mile round trip and my chirrup is definitely getting worse ( more frequent, not louder).

I'm afraid it's bad news, the noise is still there and occurring more often now.

Just a thought but could it be the alternator freewheel/overrun clutch? I don't even know if it has one but they can start making funny noises when they start to sieze up! |

Anyone get to the bottom of this issue? Mine has done it for best part of a year.. |

I regularly hear a flutter which I suspect is the noise that most others are hearing. I'm happy thinking it is the secondary turbo inlet isolation valve because I can cause it to occur by having revs and throttle opening that begins to use the secondary turbo then back off the throttle slightly, at which time the noise occurs most of the time. I had the same symptom with my 3.0 D4 - driving just on the engine load and revs where the secondary turbo begins to be used, then backing off slightly.

Mine mysteriously cured itself for weeks and weeks (over a very wet winter period if this is significant? ) , but every now and then I think it is starting up again, but so randomly and far apart I am no nearer solving the issue.

mine still does it on occasion, but I'm 30000 miles further on and it hasn't gone Kaboom so im thinking its at worst annoying and at best a cool noise.

No blow-off valve fitted to these engines. |

Can those of you who are concerned go out in your car and find an incline, then reverse up it covering your brake pedal with your left foot! Even partly applying your brakes to make you rev it higher. This should induce the secondary turbo chatter...

I reverse up an incline to get in my workshop and I get the chatter every time as I have to accelerate and the back off quick....

Thanks for putting me out of my misery, that now is the only thing I could not explain but you have described exactly what I experience ie pushing my tin tent back into the driveway and as was described by the Mr Northenmonkey?
