Anyone got any questions on the Project: Repairing the Air-Oil Separator for your Porsche Cayenne?

I see comments on the project article that the part number stated for the diaphragm is incorrect. Looking in the catalog and PET, that seems to be accurate. Does anyone know the actual part number for the diaphragm or even for the entire cap assembly? I do not want to replace the entire valve cover ($500) in order to remedy a torn $5 piece of rubber. (I haven't opened mine up to inspect it, for fear that opening it will tear an untorn diaphragm and lead to the $500 price tag to get the car back on the road.) Thanks for any pointers to the correct part number.

For those that have replaced the diaphragm, I am having a heck of a time getting the cap off. I work on loosing the tabs but it will not pull up and off. I noticed that the cap can slide back and forth in tab slots. Is there a trick to getting it off that I am missing.
