I've got a 1.8 TFSI A4, and it's making a whining noise.

It's audible if you rev the engine, and when driving. Very pronounced at lower speeds.

If you depress the clutch, it stops. But, if you rev it'll whine again.

Going down an enclosed street, with the windows open, when you press the clutch it stops making the noise. If you then rev'd with the clutch still disengaged it'll make the same sort of noise.

It's not the serpentine belt, or associated pulleys, because I've had that checked by a garage and with the belt removed it still made the noise.

Any idea what it might be?
