I've often wondered that on mine. I think it's very noisey, clicky, ticky if you know what I mean. |

Do you get any noise/vibration around 2500?

No mate I don't. Bare in mind the second turbo usually kicks in at 2500rpm. |

Bumping this. Would anyone mind recording the noise of their HPFP through the rev range?

Not sure how much use this will be, but I recorded this the other day as I wasn't sure whether was a noise at idle or not:

Bit of back story to this.

I also suffer from the irritation of the ticking and clicking. Will also record tomorrow at both idle and faster. I do get an element of vibration but will confirm at what revs again tomorrow. My fan does wobble a bit when not engaged but runs true when engaged, is this normal ?

I think it'd be a great resource for the forum if we had a library of noises/videos like this, what sounds normal for each engine and what doesn't, I'm sure it'd help when diagnosing problems.

If you have vibrations around 2500 check front drive shaft. Mines did that then eventually broke🥴 |

JNC, I did a cold start the other day and while looking under the bonnet everything was quietish. Then after about 10 minutes of idling the pump went really loud. Do you think the fuel cooler has a valve on it that suddenly opens and the pump has to start pushing fuel through it and that could be the noise? Clutching at straws here. |

I took it for a drive this morning. It is definitely quieter. There is still vibration at around 2500. But no noise as previous.

Vibration can only be caused by something spinning or wobbling. Have you checked all the pulleys are running straight? Do the drive belts run smooth? I've heard the crankshaft pulley can fail. Look to see if it wobbles at all. |
