Hello there, I've got a problem with my 55 plate S4 Cabs roof. Yesterday I decided to put the roof down for the first time in months, I operated the roof button, the windows lowered and the front of the roof unhitched from the windscreen. It proceeded to move back ever so slightly, then stopped. Now the roof light is flashing on the dash, the roof isn't secure and will not close. I followed the guide on youtube and manually took the roof all the way down, then put it all the way up again, hoping that it would reset the system. It still has the same problem of unhitching, then stopping part way through. Now when the car starts up, the roof light will flash for a few seconds before going off. Is there a possibility that there are components which could have failed after months of no use? Any help would be greatly appreciated.
