I have some questions about wife's car...Last year I switched her from her 2010 Cayenne to a 2017 Cayenne. Both cars were the "GTS" and she had spec'd both to her likings and bought them new.

Right off the bat she complained about low power, slow, doesn't start fast, poor throttle, …, and that she missed her old car. In my arrogant way I told her about "turbochargers" and asked her to press "sport" button which she always does now. She does like the electronics, backup camera, B&O, and performance at speed.

Finally after 20 months, I drove her car today for about 150miles and then installed winter snow tires... And I am very disappointed at the throttle response and the turbo lag. Actually, I am really shocked, and will take the car back to the dealer. For reference, I have been a 911 Turbo owner since 1993 and currently 5 911 Turbo/GT cars, so I know Porsche turbocharged cars well.

Questions:

1. Anyone here has reprogrammed throttle angles or are there TSBs or such? (This car is kept in CO and I need to make sure that the car passed emissions).
2. When you press "Sport" button, PASM raises car to mid-height. She prefers driving in the "low ride" height. I had installed a Cargraphics lowering module on the 957, but I cannot find one for the 958. Any advice to lower the car? Or a way to program the car to stay at low ride height when "sport" is pressed.

She likes the car enough that doesn't want me to get rid of it... So I could use some input on ride height and better performance.

I believe there are complaints about the new turbo V6s and a ECU reflash by the dealer cures it. Its happening to Macans too.

Known problem with the V6 - do a bit of searching. Basically the knock sensors are too sensitive and retard the ignition well before knocking/pinging is actually occurring. There is an ECU flash to fix this. Your dealer should know about this.

Some of what you're describing may be in this thread: https://rennlist.com/forums/cayenne-...-power-11.html

Have the software updated. Here is the bulletin the dealer can reference for the software update, i'm not sure of the software version but i also showed them this: DME update as per TI 2470 / DME update ATI 1704

tgavem, I appreciate the information. I asked someone and this unit and it does not hold suspension at the lower height.
(And I hope that you are enjoying your T, great cars). I contacted Cargraphic again and ordered the lowering module. I had the similar module on her 2010GTS, and basically at "mid-height" you are running 10-15mm lower.

Lessons learned here: I will start paying attention to her car. I trailer my own pcars to "my" tech about 100miles away instead of letting the local guys touch them... I will get the TSB on the (dead) pedal, add the Cargraphic module.

Merry Christmas...

After we purchased our 2014 Porsche Cayenne V8T my folks purchased a 2017 Porsche Cayenne GTS and they are nothing but disappointed. They grew up in the V8 era of muscle cars and are regretting not having purchased a Jeep SRT or Trackhawk. I only see them once every 2-4 weeks...but each time i do....blah blah blah bickering about their 6 cylinder Cayenne that just sucks. I've driven it and i think it's a great SUV...i wouldn't sell my V8T Cayenne for it....but it's Porsche build quality which means something. I'll let them know there may be a solution to the turbo lag issue as they are consistently using the sport button to "change gearing" and make the vehilce more enjoyable (....is how they see the button working).

Just drove 1700 miles to escape the cold north. Once in warmer weather the turbo is running the best it has, 29k miles on vehicle. Recently had the Transfer case replaced which has resolved the last of the uneven power. Making sure the software is installed and the transfer case is working correctly is the first step. The turbo boost is working now how I think it should. There still is an issue when after driving in sub freezing weather for a few hours at highway speeds the turbo boost is erratic. Problem goes away as soon as the temps are in the 30s. 2nd time this has happened but very difficult to recreate. Doesn't occur in normal daily driving in cold weather. We did get 20mpg overall on the trip at speeds consistently 70 to 80 mph except in Florida where a large amount of time is just sitting in I-75 stopped traffic. While the 3.6 turbo isn't a Porsche fully developed engine it does the job. I still think it is the weak part of the GTS. Don't need more power just more refinement. More power is what the Turbo model is for. Hopefully they will have a more refined engine (4.0 turbo) in the next one.

Wow, good to know as I was considering a newer GTS but have not driven one. I'm going to stick to a used CTTS to eventually replace my current CTT.

On snow wheels/tires.



Getting the car detailed/wrapped a little bit makes my wife happy. She likes the stripes, I just said YES MA'AM...next Saturday it goes in for service.


Hey 4ocious...how is that 7TT? I had mine for 7 years. I would recommend to stick with a V8 CTT/CTTS

Others have addressed the engine issues but I would suggest asking the dealer to look at the PASM as well

Although I have a 958.1 GTS, selecting PASM lowers the car to the 2nd lowest setting (2nd only to "loading/unloading cargo") since you mentioned that the ride height rises when "Sport" is selected.. that's doesn't seem right
