Hi Clive, did you get this sorted as i have recently bought a 2009 X-type jag and both drivers side windows do this exact same thing. Has to be button pressed 8 times to get the windows on the drivers side to move up a few cms and will only move down a few inches each time but only needs a press each time to move down. But to get drivers side windows up, you have to press the button up 8 times at a time to get nthe window to close a few inches
