Porsche Repair Questions? Ask a Mechanic for Answers ASAP
Hey there, thanks for the question.
What did the update? did they reprogram the throttle? and the Transmission? Do you know for sure?
I know alot of the early cayennes had alot of issues with throttle response with the adaptations that were being made for economy. This for the most part disappeared once the sport mode was added.
There have also been some issues with downshifting that appears to be a lunge but that's mostly resolved from a reprogram as well.
Aside from that there is always the chance that there is an issue with the accelerator pedal position readings or the throttle itself causing the delayed response.
Lastly there is of course a mechanical isssue with the torque converter or TC seal that can cause issues. Both highly unlikely on a 2016 Model.
If you have the transmission is comfort mode, use the sport mode and see if the delay dissapears. If so then you KNOW it's likely transmission programming related.
Do let me know what you hear back.
In the meantime I can check to see if any other techs have seen this issue on newer models.
Just checking to see how its going.
I wasn't able to get anything else of much resource from others that would help on this one.
