So I've replaced the Inalfa control module (twice, with different modules, one of which I know for certain works in another XJ perfectly). The problem is that the sunroof will not park in its closed position - it travels past this position and then tilts, dropping back down to slide and proceeds to slide to its end open point. Sometimes the one touch operation will work, but more often than not, it requires manual holding in of the switch, in either direction - in any event the self park still doesn't kick in. Apart from the control module, I note that there is a PCB inside the roof console - is this prone to malfunction and cause the problems I have? Most people I have spoken to are certain it's the control module, but I have effectively ruled this out by substitution with a known working one. Any ideas anyone?

Hi,

not seen the xj sunroof before, but seen quite a few others, theres usually micro switches and cams for location positioning, sound like its either faulty or new adjusting

cheers
