Hi.
Thought I'd put an update incase anyone has this problem in the future. It is a absolute nightmare but it works so just bare with it. So come up from the bottom with a rod with a 90° on either end 30mm on one end and 100mm or more on the other this is just a handle to twist the bar. A inspection camera with a light is a must or your just fishing in the dark. I taped my to a extend magnet. So I could get a decent view and let go. It's very fiddle and and stressful and annoying but so you want to there the bar up and using the camera get the short hook in the lower catch and twist the bar counter clock wise to release the bonnet. Took manny attempts as it pops out drop it ect it all so takes alot more pressure than I thought it would but it works so just keep on and bear with it. Hope the photos help make more sense of it all.
