Just had another look at the issue. Took the WG cap off and all looks ok. Couldn't find any holes in the diaphragm. Also tried the suck test and it seemed to hold vacuum.
So, based on the comments above, it could be excessive leakage in the shaft, or a weak spring. I think I'm going to have to send it to a specialist

Its normal, dont worry about it. As per your first post if I pinch the hose going from the N75 to the wastegate and it holds boost pressure its fine.
I would be interested to see the inside of an uprated unit like the Tial valves, are they airtight or do they leak too?
