My car(991.2 cabriolet gts) 's key only had three buttons, and the fourth button was unmarked and blocked.
I cut a hole in the 4th button that was blocked and made it work, and then used the , code to open and close the top . Unfortunately, I don't remember what I coded to make this work, but it wasn't anything too difficult, just one of those simple on/off things.
Just wondering if you discovered what code you changed to get this to work with that 4th button. I have a 991.1 and I've been able to get the keyfob to control just the windows but not the top. Much appreciated.

I'm likewise curious. I have a Targa and got a SmartTop module for it. That handles a bunch of things beyond what ( I think) the built-in systems will provide.
I am also curious to know what coding gets the vehicle to recognize the 4th button. I suspect I'll have to remove/disable the smarttop in order to better experiment with the 4th button programming.

I was never able to get it to work. Just went with smart top.

I would gladly help you find the coding with PIWIS. Yobiwan posted on my coding thread asking the same question. He must have added the coding for the 4th button. PM me if interested
Can anybody help with the coding on the piwis3. Trying to figure out how to have the brake light under the spoiler.Come on all the time as I have used that light inside a static spoiler.And already coded for it to not go up till 250 km.
I recently purchased a Launch X-431 PROS and when I examined my 2017 C2S I found that Auto Stop/Start can indeed be programmed out to not need to be dependent upon the OEM key fob being used or some owner/user accessible memory setting. I requested FVD, the supplier of the DME tune that I purchased from them, to code out the Auto Stop/Start function and they did. That status is clearly shown in a scan and when digging down into the various menus for the Instrument Cluster.
I've only used the X-431 scan tool to reset the maintenance service reminders and the water temperature dash gauge display, and hopefully the maximum boost pressure display [I have not had a chance to test drive the car since those changes]. There appears to be myriad coding changes that are possible for those who know what they are doing or those who are more confident and experienced than I am in this area.
I recall seeing a scanner / coding protocol, I think on the Cayenne forum, in which the writer said that it was possible to learn the exact amount of motor oil still needed to be added to entirely fill the system after an oil change, but unfortunately failed to save or print that protocol. I'm wondering if that or a similar protocol is available for 991.1 or 991.2 owners. That would save having to check the oil level as you complete the oil fill and avoid the potential delay due to the engine / oil needing to be above a minimum temperature to read on the dash display gauge in the MFD.

Have you considered, instead, rerouting the wiring from the deck lid third brake light to the new static spoiler light? Check out my recent thread on a ducktail spoiler I installed, sounds like what I did might work for you?
Sorry I didn't see this post when I originally made mine, but here's the coding for the 4 button/convertible top. I could not use my Launch X431 to do the coding. I had to use PIWIS.
