Also proves the point whose lawyers (VAG's) are more persuasive. MBUSA offers the windows-with-fob control feature in the U.S. market. Porsche does not.

Same litigation environment, nearly identical vehicles (GLE and Cayenne) and generally the same general customer demographics. But different product decisions.

 

You can open the windows and sunroof with the fob on a U.S. market Mercedes but can you close them with a fob? You can close them by continually touching the lock area on the drivers door handle. That's similar to the last Lexus LS that I daily drove for many years. I could open the windows and sunroof with the fob but not close them. I could close the windows and sunroof by putting the key in the driver's door and continuously holding the key in the lock position. But in some other markets, windows and sunroofs on Lexus could be closed with the fob.

Sometime after 2006, the capability of opening windows and sunroof with the fob on Lexus vehicles was changed from being a default setting to an optional setting that could only be implemented by a dealership tech. There were many posts on Lexus forums from people who inadvertently opened their windows and sunroofs while their cars were sitting outside in foul weather. I suspect that the change was due to complaints.

Opening windows and sunroofs with fobs used to be a fairly common feature and maybe it still is on some vehicle brands. I remember being surprised that I could open the windows on a rental Honda Accord with its fob during a memorable vacation in 2006. .

 

Press and hold the unlock button on the fob. Press/hold lock button to close windows. I suppose it’s possible that the previous owner had it coded?

 

Doesn't work on a non-coded MY20.

 

A comment on the 9XX Comfort Windows YouTube video said that this setting can be customized with a fairly inexpensive Launch scan tool but I don't know if that is really true. There are a number of YouTube videos showing customizing Cayenne 958 settings with a Launch scan tool but I haven't seen a video showing it being used on a Cayenne 9Y0.

 

I was able to successfully code this in my 9Y0 2019 Cayenne Turbo today with my Launch X431.

I followed post #390 in the 992 coding thread from rnlst_log.
For the X431, it was:
Rear end electronics
Search for coding items: "comfort"
Coding value-Comfort_operation : Active/Open (write code)
Coding value-Comfort_operation_radio_remote_control: Active/Open (write code)
Memory settings for vehicle-Comfort Opening Window (whatever windows you want: ie: driver side, frt. pass. side): Active/Open (write code)
Memory settings for vehicle-Comfort Opening Rear Window (whatever windows you want: ie: driver side, frt. pass. side): Active/Open (write code)
Memory settings for vehicle-Panoramic roof comfort opening: Open/Active (write code)

Then go to your PCM, Settings, Locking, Comfort Opening and you can select Windows, Windows and Sunroof, Sunroof
By default, your sunroof will "tilt" when open but you can go back and code it to "slide" open if you wish. I opted for tilt as didn't want anything to drop into the car aka leaves, bird droppings while open.

Now, click unlock and holding it will open what you have selected and then clicking and holding lock on keyfob will close!
