    If you rev it without load it might get there but it shouldn't when in gear unless you have had it remapped.

    I think you could be just about to have manifold trouble, if there's a leak at all it will introduce air and fluctuate the idle, don't take this as a diagnosis because it's an expensive fix if done properly, or a few quid if you feel you can do the repair with the tap washers, also the air meter could be playing up, I had a 15k one that was doing it when cold, might be worth a chat with a Vx mechanic cos I don't think it will be a one off.

    When cold it shouldn't rev over 4000rpm as the ECU limits it on start up until warm.
