Please can someone help!

I have recently purchased 03 plate Tdi 100 classic with 155k miles, I have a most annoying rattling coming through the gearstick between 1400 and 2000 rpm.

I have checked that the exhaust is not touching the gearshift mechanism, I know the car had a clutch fitted just before I bought it and was thinking that maybe the Dual Mass Flywheel was not replaced ( WOULD THIS CAUSE THESE SYMPTOMS).

Any Help would be greatly appreciated:)

I know some early vRSs had rattly gearsticks, but that was at idle. I think it was a fairly easy fix (an adjustment and/or new pin somewhere or other). Assuming it's the same thing, it shouldn't be too hard to put right...
