Hi. a couple of times now my soft top won't go up when I press the button and so I have had to raise it manually. The display gives no reason or fault as to why it hasn't raised. (If the boot is open or the storage shelf is not in position, the display pings and tells you why the roof isn't operating). The roof then operates normally for a time but then fails to raise. Any ideas why it's happening or how I can sort it. It just makes me a little nervous about putting the roof down anticipating it wont go up again electrically. Thanks.
