cayenne diesel 2015 gear shift
Discussion
Bought a Cayenne Diesel 2015 with 2000 miles on the clock. After a few days drive, I have realised that the gear shifts too fast. For example, 40 miles in 7th gear and 50 miles in 8th gear. As a result, I can feel vibration from the transmission. I have to apply the throttle really hard in order to let the gear adjust to a lower gear. It is like driving a manual car, higher gear with low speed makes the transmission vibrate.
Meanwhile I have found that the car does not down shift until I apply the break. For instance, driving at 40 miles per hour and then release the throttle, the gear still stays at where it was even when speed drops to 20 miles. At the same time, I can feel the vibration come from the seat.
If I select Sport , the problem does not come.
Been to the dealership and they updated a software, but after a few days drive ,the problem came back again. Now they use the adaptive gear box to convince me that this is not a problem. I appreciate that the adaptive gear box is to make driving more pleasant according to different driving styles, it should not cause uncomfortable experience.
Would like to hear your opinions.

Hi! Do you still drive this cayenne?I have exact the same issue with my 2016 diesel...I bought it new, experienced this and the dealer changed the transmission under warranty.But nothing changed!I have requested to try another cayenne and while testing it i've realised that the same thing is happening!Very strange...
I supose that your dealer is right regarding the adapting on your driving style...so can you tell me is anything changed on your cayenne so far, did it adapt??
My biggest concern is when the rpm needle approaches to 1000 rpm (in 3rd gear) I hear annoying grinding sound and when it drops bellow 1000 rpm- after a few second it shifts in 2nd gear!

Sold my Cayenne Diesel as I couldn't live with the Tiptronic box. Changed up the gears too early at low speeds and then when in slow moving motorway traffic would be dropping cogs causing jerkiness.
Raised it with OPC who 'flashed' the software and inspected it to tell me there was nothing wrong with it. Pity PDK was never an option

The engine and transmission are specifically tuned so that there are definitive differences between Normal / Sport.
The economy of the Cayenne in Normal mode makes for a fine high-speed, comfortable, motorway-muncher but you can alter its charactistics with some pre-emptive throttle application; much like the rest of the non-manual transmissioned Porsche range be it Tiptronic or PDK.
As in the OP, using Sport mode changes the character instantly but also fixedly. When you want to use Normal mode but want some added responsiveness - for instance rolling up to a roundabout - just before you should lift off the throttle, tap the pedal quickly (the key is the speed of application) get it right and the transmission will drop one or two gears and the additional engine braking will reduce the need for braking as an initial positive; now though, the transmission is already in the correct gear for moving away smartly - with the engine already up and away from idle and the nice turbo shove ready (and on time!).
'Coast' mode - where the transmission is disengaged after the throttle is released; can be useful - and is used as another way to reduce fuel consumption longer term - but can be inhibited by instead releasing the throttle with a 'snap' rather than rolling off gently.
It is also worth noting that switching off 'Start/Stop' will inhibit 'Coast mode' too.
The transmission adaption in Normal mode errs towards smoothness and economy - but it can't predict what you are going to do next; you need to tell it.

pope,thank you very much for the detailed instructions!!!I will try this style of driving in normal mode and see what's happening.
What is your opinion about driving all the time in Sport mode??I know the fuel consumption will be higher, but what about the transmission and engine-do they wear out faster if you drive it all the time in Sport-or what can happen to my car if I decide to stick to this sport button???

Sport mode in general use will make the car feel more urgent; you'll have to manually switch on auto start/stop (by deactivating Sport when required) and as mentioned before the Coast function will be inhibited. The engine will run cooler (the DME controls the engine temperature with a bias to a lower operating temp to account for the increased performance demand). The transmission will also shift more positively (more noticeable changes).
Economy may improve slightly in certain situations - slowly lugging up to 70mph from a standstill will use more fuel than a burst of acceleration up to 70mph then maintaining the speed (?) - but in general expect consumption and range to take a hit.
Getting used to a car and learning to play to its strengths is half the fun IMO.

Have to say I haven't noticed this in my V8 Diesel S....we're three months/4500 miles into ownership and it drives superbly. The car is definitely not using 8th gear at speeds of 50 mph. Is this with the 3.0 or the 4.2 Diesel ? Although given the extra grunt of the 4.2 you'd think that would be changing up to higher gears quicker.
Hi pope...hope you are still there...I'm getting a whistling sound on my cayenne 2016 (wind whistle) while driving on a motorway.It seems the noise is coming from the drivers mirror zone.I tried to drive with closed mirrors and the sound is not there...Should I be worried or is it just mirror design that is making that whistling wind noise?
Thank's for help!
Thank's for help!
Still here; been off-colour of late so haven't been on much.......
The mirror design changed slightly from E2.1 to E2.2 Cayenne; and presence of noise is quite common. If the car has any sort of paint protection film on the mirror caps or mounts that will increase any whistling (the edges of the film create turbulence at speed).
Hard to say if the noise is above 'normal' level; the new car guarantee will cover wind noise so if only for peace of mind get it in to your OPC and tested against a similar car.

Good evening. I bought a 14 plate Cayenne S Diesel about 6 months back from an official dealer so it has a 2 year warranty. It had about 27000 miles on and now up to 35,000. I have noticed recently that when I accelerate (not harshly) up slight gradients, I sometimes get a juddering sensation. It continues through a gear change or two, which gives me the impression it's drive transmission related and probably not the gearbox? Probably best just to book in for an inspection, but would appreciate any experience, to match up with the response that I'll get?
hello pope!over a year i didn’t ask for help, as in the meantime everything was ok on my cayenne diesel 2016...
now I have a strange short vibration sound when i’m stoping the car.i can feel it also when i want to stop in reverse.the vibration starts buzzing and suddendly stops when the car is stoped!
Pope do you have an idea what could be the issue?i have opened the hood and visualy checked all the covers-it seems nothing is loosen.
Please help pope...thank you very much!
