Xantia HDI noise

My Xantia HDI engine gas started making a light tapping noise at 3000 rpm and above. It sounds like a noisy tappet and is speed related. Also it seems to vary in intensity, some days its almost gone alltogether, on others it sounds like a tractor ! Any ideas ?

First stage - check all ancilliaries and drive belts - they can make a surprising noise.
secondly - is it transmission related? - does it make any difference if the clutch is depressed?

There wa a post about this on HonestJohn's forum a couple of weeks back - related to the crankshaft pulley breaking up. Symptoms there were rattle at cold start, but I would certainly check the condition of this pulley.

All belts seem tight, no difference when clutch pressed. May be louder under load, but not significantly.

yes,sounds like a crankshaft pulley to me,you will probably find it will get gradually worse.

Hi
I've got the same problem on my W 2000 Xantia 110 HDI 62000. I've not sorted the problem yet but when the auxillary drive belt is taken off the noise goes away. Still investigating.
Cheers
