no hydraulic problems, the switch that was broken tells the system that the boot lid is fully open, so it can continue with opening the roof panel. It would seem that the whole system is a progression of micro switches that have to operate in a sequence. what would be useful is a diagram showing the location of these switches and sensors, if I had known which switch was faulty, I could have changed it in 15 mins !!! the switch was part no:170 820 11 10 , cost $20.
