As others have indicated, up a certain point the start/stop option used to be selectable on the MFD. But as of my 2017 GTS it's a feature that cannot be disabled (emissions reduction being the factor). The only way to change the default behavior is to add an in-line module under the center console that remembers the settings. I have this installed in my '17 GTS and it works perfectly. It's invisible to the rest of the vehicle systems, so it won't interfere with anything the dealer might need to do using the PIWIS diagnostic system.
It functions by mimicking the way the console buttons are pressed. It listens for the presses and remember the last settings made, and waits a few seconds after the vehicle is started to re-send those button presses.

I use the T9 memory module to remember the start-stop button setting. Works great, and install was pretty easy: https://t-design9.com/memory_module_...8_install.html

This could be an indicator of your battery condition. There's a number of things the S/S feature uses to determine if it should activate or not and I believe battery voltage is one of them. As in, don't leave you stranded stopping the engine if it senses it wouldn't have enough power to start it again. But I don't know this for certain.

2015 Cayenne S here, anyone know how to disable the auto start/ stop feature on this vehicle besides manually pressing the dash auto start button every time?
I mean, really. I start it up sometimes 3 or 4 times a day. 350 days of the year. That's 1,050 times a year and over 5,000 times over a 5 year period.
When I owned a 2019 Jeep Cherokee there was a cable that I discovered behind the battery that when disconnected it permanently disabled the annoying start / stop feature and never had to press the dash button ever again.
Was wondering if there was a workaround for the Porsche Cayenne as well.. Thanks for any feedback. YouTube was of little help.

What about saving the driver settings on the driver door? I believe my 2012 Turbo keeps the last setting the switch was in.

Any update of this? I was seeing the 'start stop system disabled' message over the weekend. Battery seems fine. Dealer can't see it for a week or so. Checked codes with POR II, ran diagnostics. Nothing.
