If you hold the clutch all the way in does it eventually go quiet or if you leave the clutch out does it change the noise at all?
Unless I’m much mistaken, I think the diesels have a dogdish solid flywheel, but this may be earlier cars-mine was MY1995 but registered in January 96.

If I dip the clutch when the noise is happening it instantly goes away-it also doesn’t happen when releasing the clutch as I pull away, only when the clutch is fully engaged. When in neutral and stationary, there is very little difference in noise when the clutch is in or out. Perhaps a hair more noise when the pedal is down but very little in the way of chatter etc. The noise only occurs when under load, not when the car is revved when in neutral.
