    i agree with the last post sounds like your dual mass flywheel is shot had a similar noise on a car in work and it turned out it was the d.m.f and it wasnt cheap but i would get it checked out by a garage

    Describe the noise when hot, and if it goes quiet when you dip the clutch and engage a gear.

    Ok, you'll know for sure if this is the case, the only reason I comment is because mine had a new box when it made this noise, and it was noisey.

    Ok, not the gearbox symptoms I had then, so thats out of the way. Possible the DMF I would suggest.
