AOS repair diaphragm available?!
Hi guys!
Just wondering if you've heard of a repair diaphragm part for 996/986 AOS. There's a guy on eBay selling a diaphragm replacement for a 986 AOS for $14.60. The item number is 381944508835 and can be found here.

I asked the seller if he had a write-up or know where to find one. I've searched in various Porsche forums and have not found any yet, many of pictures of the AOS internals but no write-up.I know the part is fairly inexpensive and the diaphragm cover is plastic-welded so, please spare me the lecture!
I believe the diaphragm cover could be removed successfully and then epoxied or JB-weld back together with the new part installed. I also think the AOS are very similar between 986 and 996 and that they probably use the same/similar diaphragm and just vary on the orientation so, is this doable? Has anyone attempted it?
Thanks beforehand for your comments.

Thats a great idea. I know that on the Cayenne the diaphragm is easily replaceable (I bought one from some guy in Russia). In the past I have "welded" plastic together using a hot soldering iron.

Not every 996 AOS failure involves a failed diaphragm. Sometimes the housing fails and there can be a coolant leak sometimes external only other times the coolant leaks into the crankcase and mixes with the oil.
Based on what know first hand and 2nd hand about AOS failures I have to believe a diaphragm replacement to salvage a failed AOS -- even if the AOS is bad because of just the diaphragm (for now) -- is really false economy.
