Hi Brian I had the same fault on my o/s/r door. We found that ford's had been tight on there wiring loom and as the door was opened and closed over and over again it broke the wires inside the loom.If you pull the rubber tube down you will proberly see the outer case of the wires cracked through. If you need things go to vw centres first and tell them it's for a sharan. I bought a rear window mechanism complete as a piece of plastic broke on my one. ford price
