Problem going into reverse when hot

[willowsdad]

Hi all. I've got a 1.8t (190) manual 6 speed. When cold it's fine, but when it gets hot it seems to struggle to go in reverse a lot of the time. I've changed the gearbox oil today and it's no different. All other changes are smooth and good, so it seems to be just an issue with reverse. Any ideas?

could be one of a few issues

could be the syncro which is worn and wont let you select reverse or it could be the clutch dragging
