Disable Auto start-stop?

Is it true that Porsche cars now have the Auto start-stop feature activated by default, and you must manually disable it every time you start the car? On my 2013 Boxster , you could disable it once, and the car would recall that setting whenever it was restarted. If it is "on" by default, is there a way to deactivate it, say with programming or by removing a fuse or a connector to a switch or sensor? Thanks in advance.

my 2015 CGTS stays on the last "setting"... no need to "always" turn off or on.. D

2016 CGTS -Ditto what D&D said. Curtis

My dealer told me that the 2017 911s all have the start-stop default to "ON". Some posts claim that this started with 2016 model year cars; my 2013 Boxster S let me permanently disable it. I wonder why it can be disabled permanently in some cars, but not in others?

Always on in my 2014, dreadful feature, turn it off every time. The sail function is useful in motorway tho to save fuel.

Someone, somewhere has got to know why it can be permanently disabled in some cars, but not in others! I fail to get why Porsche allows you to disable it whenever the car is started, but not on a permanent basis??

The reason it can't be disabled now has to do with EPA testing. If the car model was certified worth auto start stop on, it must be activated when starting the car. The cayenne was the first model, the 2015 I believe. Sent from my iPad using Tapatalk

If that is indeed the case, why have several 2016 owners (like Curtis above) been able to disable it? Does anyone know if the function is controlled by a specific circuit or fuse in these cars?

I believe the 6 cylinder model was the first one to have it on mandatory. I have gone through multiple tries of coding and programming with the piwis tester to no avail. Maybe the aftermarket can find a work around with programming. Sent from my iPad using Tapatalk

I'd be willing to pay for any sort of workaround. That feature is just a plain joke in a sports car. Jaguar has it enabled in the FType, but you can easily disable it by unplugging one connector in the trunk.

Interesting about Speedgirl’s 2014 always defaulting to ON; my 2014 BS starts up with it OFF. I can’t remember if it’s always been that way or it just remembered my last setting.

I read a few posts that stated that the ability to disable the feature was linked to having the memory seat package. I had that on my car, and it permanently was off, but it seems something may have changed in some cars built for MY 2016. Who knows?

I have a 2013 981 BS and the feature is disabled in the sport mode. Actually I like having the ability to activate it, since there are traffic lights in certain areas that I drive that have intervals as long as four minutes. Having the engine off for four minutes is my small contribution to reducing CO2 emissions and gasoline consumption.

Choosing to use a feature like this is one thing (desirable); having to manually disable it every time you start up a $100k+ sports car is just plain stupid. These cars use premium gas, and are tuned for performance, not fuel economy. if its economy I want to pay for, I'll buy a Prius. Or even a Tesla ...

2016 CGTS- Allow me to elaborate in view of all the comments. My car defaults to starting with Auto start/stop--"ON" However once I use the console button to disable this function, the car "remembers" this setting and it thereafter always starts with this function "OFF". I leave it thus, much like down shifting to use compression braking as opposed to the wheel brakes, in the belief that wear and tear on the starter motor and associated equipment is more detrimental to the car than using the brakes, or letting the engine idle at traffic signals. I realize this is not the "Green" approach. Curtis

2014 Cayman off unless activated, 2016 Cayman off unless manually activated. Not sure if it is related but both have 14 Way memory seats.

An side thought.... what IF Volkswagen had provided a "switch" for "performance" that defaulted the emission test cycle settings... so the car was "defaulted" to the "legal" cycle... but then allowed the driver to switch to the "performance" emission settings -- sounds like our auto-start set to "on" unless the driver wants the performance the car was purchased for??? Hmmm... hind-sight is always better, but what if?? PS... FWIW, my 2015 Cayman does not have power seats --- it has the simple two-way sport plus seats standard in the GTS trim... yet once I turn the auto-stop switch to "on"-- eg. the console lighted switch is light -- it stays that way until I physically turn it "off" to allow auto start-stop. If the 2016 models are different I cannot say. W/r to wear and tear on the starter --- the system does not use the starter. The motor stops at specific rotation points and for "re-start" simply spurts a bit of fuel in the appropriate cylinder and fires the plug -- spinning the motor enough to start the motor. The system needs the motor to be at a specific minimum operating temp for it to work... that's why with the system engaged, it will not stop-start when cold. This per a detailed discussion with staff at the dealer --- FWIW. D

Yes. Greens are winning on all fronts, and new Porsches will default to ON,as they already do in some EU countires. I already have a customer who is waiting for 911 , confirmed by dealer to default to ON. He wants to do start/stop mod (default OFF) immediately upon car arrival in May. But somebody can beat him to that... I'm pretty sure it can be easily done for start/stop as I do it for sport mode. But I didn't try yet. So if somebody wants to participate in experiment - contact me.

Please contact me if you are really interested. See my post above. And we are both in Michigan!

My 2016 GTS is exactly like D&D's and I have the two-way seats also. I did not know (obviously) about the restart sans starter motor (Thanks D&D), but I'm still not enamored with the concept so mine will stay "OFF". Cheers, Curtis

T-Design9.com now offers memory module for Cayenne 958 that will take care of auto/start/stop, sport and PSE . All these buttons will stay as you left them before shutting car down!
