Annoying Whirr When De Clutch

[Seatdriver]

Hi all, new to the forum.

 

I have a 2003 1.9tdi Sharan 90,000 miles which has just recently developed an annoying noise when cold. I will attempt to describe it (there was a thread somewhere on this forum but I can't find it again!)

 

Here goes

Start engine, put into first gear (no problems with selecting gear or clutch take up,rattles or vibrations)

Pull away up hill (turbo whistles happily)

Lift off accelerator,putting down clutch to go for next gear and :

There's the noise, sounds like a dry bearing but only ever hear it 4 times as it slows and gets quieter (whish,whish,whish,whish) best I can describe the noise

It will make the noise if I put my foot hard down and then lift off the accelerator as I press the clutch down (any gear includng reverse), and it doesent matter what speed I am doing, the noise is the same pitch and speed until it can no longer be heard. It lasts for several gearchanges (typically about 2 minutes of driving then stops!)

 

Once engine has warmed up this noise never appears again unless the car is left for over a hour and it may come back once.

 

The car starts first time every time, is clean in every gear (typically clonky selection though), pulls well right through the rev range every gear and uses next to no oil that I can tell.

 

Oh and if I rev the engine when cold whilst static there is no trace of this sound.

 

Any info would be appreciated as its like an itch I can't scratch and its bugging me.
