Yes, the COV part number is 7PP-906-283-F, but the COV Wiring Harness is 991-612-944-00. SKU991WHAR is Suncoast's internal part number, they mask Porsche #'s for obvious reasons.
I’ve had PNA replace all 8 of them about 4 years ago. Now I had the warning twice since that time. None of the valves seem like they’re not working, so I’ve cleared the code and all seems good. Not sure what this could be.
A friend of mine just had this same problem with his 2016 GT3RS: "my car showed this warning sign 2 days ago so I took it to the dealership they cleared the warning the mechanic told me if my valve on my exhaust opening and closing which they are not I believe they stuck on open position he said you have not that side muffler delete got anything do with this problem but go change the it back and install your side mufflers and bring it back so we find out what is wrong with it since then I been reading about 991.1 from 2012 they have had what is called “ change over Valve “ problem there are 8 of these solenoids that control all vacuum system in these cars one of them is the one control the exhaust valves strange thing is when I use to open the valves via switch there was no Drone but now that valve are constantly open I have this bad drone and sound too loud at any speed and sound bad .
I can't seem to find this specific answer in the thread, and either way, maybe someone can answer it again since the thread is getting pretty long.
Is the new wiring harness compatible with the old valves as well? For example, if you were only changing some of the COV's to the F-revision, can you leave other older COV's, or do you have to replace them all?
