This model was available on the UK market but I doubt if many still exist.It's a long time since I've seen one ,but if I recall the most common problem was the drive gears that power the roof section backwards would crack and foul the system.If you are going to get involved with this then get hold of a workshop manual which gives a step by step test procedure otherwise you are going to waste a lot of time .Ecu for the system is in the boot.hth
