Droning noise still there! (Xantia 90Hdi)

I still hear a droning noise when my 90Hdi is idling and the engine is warm.

I'm pretty sure it's not fans, although it does very much sound like that. Certainly rad fans are not on.

A clue? The noise stays at constant pitch if I rev the engine.

I got the car at 38000 miles a year ago, the noise started maybe 8 months ago, it happens quite often but not always and canreally only be heard when on tickover.

Can anyone please suggest what I might look at?

Wondering where about, or what side of the engine the drone is coming from. The lower pulley (drivebelt) comes to mind. Sorry I can't be more helpful.

If its not at engine speed its unlikely to be engine or ancillary related. Can you hear it from outside the car?

Like I said in the last 3 posts, have you looked at the fuel filter / lines / pump....

Noisy fuel pump in the tank ?
