I have engine noise accelerating up to 3000rpm then it drops off . Starts at around 2000rpm.
Best place to start finding the noise.
I have just had the cam belt and aux drive belt change and no mention of problems with the crank pulley (what is in there to make a noise anyway thought they would be solid?)

Re: Engine noise accelerating.
What sort of noise is it, rattle /screach
what area is the noise you hear,
it might help others to give you an idea what and where to look for,

Re: Engine noise accelerating.
If it's a light rattle, (like a petrol engine pinking), it's normally considered to be a sign of worn injectors. It goes away at 3000 RPM, because the HP pump changes to using all 3 of its pistons at that speed.
Not usually worth worrying about, my prevous Xsara HDi did it for 100k & it didn't get any worse.

2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

Indeed it is a light rattle... I posted a pic of my injectors at idle one seems way off the other three
