Sir you are a god send. After your advice I did the unmanly thing and read the hand book to find, that the fuse is shared by the cigarette lighter also. On investigation I was to find a screw sat in where the lighter unit was supposed to be making a nice conection. Thus blowing every and any fuse I cared to put in.
once again I thank you sir.
I am now off to enjoy a nice long journey with the sunroof OPEN.
