Well that was easy... And I found the problem.
You're right, the clips were broken! Looks like the autoglass guy managed to break 2 clips and went and applied windscreen sealant glue to both, one had excessive glue applied hence why it wasn't sitting flush. The foam seal;ing that runs along the bottom of the cowling was also broken by the centre points so water running down into the drainage area was also going down via the broken seals and depositing in the cabin air filter area. Pictures below to show both instances:
You can see that water has reached the cabin filter in 2 areas directly below the broken seal points on the cowling.
I will be needing a new cowling. I've messaged Autoglass about this as the guy should have at the very least mentioned it rather than bodging it together. I want the promised good will gesture and I want a new cowling supplied by them, which I will then fit myself.
