<strong>Sorry it took so long to reply,
Variator adjusts the position of the inlet camshat rlative to the exhaust cam, thus changing the length of cam overlap, to give the engine a flatter torque curve (apparently), however, you may have noted that the power of the TS 16V engine improves rapidly as the revs rise - mine is far happier at 5000 rpm than it is at 2000!!!
Eventually the variator will stop advancing and retarding the cam, but I don't think that the failure of the variator will prevent the cam operating correctly (it just won't always be in the perfect position, as I'm fairly sure it only adjusts the position by 5-10 degrees). You will notice the power drop higher up the rev range, and it is likely that the powercurve will not be as good as it could be - the best thing to do to see if the varitor is completely creamed, is disconnect the cable to the actuator (above number one cylinder just above the cam cover) and take her for a spin - if there is no noticable difference, then it is time for change..
