Not every time, but more than 50% the roof closing hits a problem. It works fine across the whole roof down movement and 95% of the roof up but the latch does not quite, er, latch... it hits it but won't join up and close properly. is this a common issue? It's like one of the latches is just a little tight, or just a little loose to do the job. When it fails first time, I have to repeat it about 5 times before it fully closes. I often fiddle with the latch mechanism on the roof and this often works, though may be pure chance. Cheers.
