Didn't want to be greedy. Not sure if this is a popular item.

It isn't as most people destroy the AOS trying to take it apart. Sometimes, the view just ain't worth the climb.

That was clever. What does it mean?

I cut open a failed AOS once to see what was inside. With the 986 AOS, I don't see a good way to open it and replace the diaphragm, then seal it back together. For all the labor involved, I'd rather buy a Porsche® replacement.

JFP's comments I found while trying to see if there was some secret way to use this part:
AOS replacement diaphragm available?! - Pelican Parts Technical BBS

The place I would use one: (Cayenne)

The juice isn't worth the squeeze.

I was wondering too how you would be able to get the AOS apart w/o damaging it beyond reuse.
