You can usually hear the whine from it on shutdown 2014 SE Loire Blue SD4 Auto (MY15)

mine doesn't make a whine only a sort or squeal is heard if I press the clutch pedal or after I switch the engine off which last for a few minutes which I thought was being made by the cooling fan module on the radiator but I might be mistaken.

The squeal could be an indicator as mine did that a few times on turning the engine off - sounded like shot water pump bearings, that stopped, then on another occasion there was a grinding crunching noise that happened once (when I suspect the gears actually were getting stripped) but what was really noticeable after that was the extra judder it gave when I switched the engine off instead of the usually completely smooth shutdown. I drove mine for several weeks before it got fixed at a service and I have to say I noticed no performance changes or oddities at all. |

My engine shudders to a stop most of the time and on the odd occasion it shuts down smooth. I might have to remove the throttle body and take a look as it must be broken. |

Certainly sounds like it! |

I was surprised when I changed mine as I didn't think the shutdown was bad, but with a new throttle body it is night and day. Worth doing as it is easy and relatively cheap. |
