hello
as title says really bought my mini with this fault but never looked into it until now as its soon to be going bk on the road and would like the roof open. as soon as I connect to live cable to the positive battery terminal it'll drain the battery evern when a new one is installed, so to use it I have to connect the sunroof to the battery use it then disconnect staright away.
also if I use my roof with a fully charged battery then turn it off to disconnect it will no turn over at all. it uses a huge amount of battery life to move the roof so why does it.
