So I was looking for the source of the leak, and decided to relocate roof motor as Ive read so many horrors stories well abosultely stupid idea. If your roof motor is in housing and there is a lot of tape around it don't touch it.
Firstly housing inside and motor were absolutely in perfect condition but once its out there is no way back I guess. So relocate it to boot space but because I fiddleed with it and now it's not in up right position oil level dropped. So I can here motor running but no action from the roof.
Going back to leak rear is OK so it must be from the front drain points. Checked membrane again and as mentioned before perfect condition all over. To summarise I made it worse by causing a problem with roof and not finding water leak - just great
