Whatever it is, spins fast.

On the clip, car moves forward/backward. Does the noise go if stationary?

At this moment, my suspects would be:

Unlikely, but still- water pump.
Check by ear/screwdriver method, it's just below and right from cam belt cover.

Pas pump.

Is engine hit enough to start radiator fan?

Manual or automatic?

Clutch gone?

Or, assuming that noise is there only if car rolls backward, maybe gearbox issue?

Best to listen which part of engine bay it's coming from.

I've heard a similar sound when the PAS reservoir is low, but it normally occurs when lock is being applied.

That's what I thought, too..

But it doesn't look (on the clip) that steering is being moved right-left..

It's a manual v40 2.0t 2001 Water pump changed 3 years ago.
I have changed the servo pump and aux belt tensioner recently but noise remains.
Noise occurs as I release the clutch and balance it with the accelerator. Normal clutch movements..no slipping and goes through the gears. No noise from the clutch when pressed down and held or released.
Totally baffled

Similar noise from my PAS when on full lock even though fluid level is correct. Mine is an old 1992 940 with mechanical PAS pump.
Does the noise appear when clutch is only partly released, ie being slipped?

It is the Dual Mass flywheel resonating and amplifying the clutch engagement noise which you normally don't hear , not at all detrimental , don't worry too much :-)

Is there any way of getting rid of the noise?
Car has gone 274000km
