Yes, still in the Sapphire Blue '17 GTS. Until they make that color available for the newer ones I'm in no hurry to make a trade. I like it, but I don't like it 'paint to sample' level of expense.

Mine seem to act up around 17k miles on the transfer case. But I don't put a ton of miles on it each year, so I'd likely be fine either way.

I suggest you check with a dealer. I may have been misinformed when I was told it was 100k mileage-based.

You can contact your local Porsche dealer and they can pull the service records on the vehicle and give you a summary of the service history. I had some difficulty getting my local dealer to pull them via an email or phone request on a car I was looking at purchasing. Finally, I went there personally and got what I needed. If you have the car with you, that will make it a little easier.

Hi all,

Just wanted to share my 2016 CD4.2, i have done 3 Ravenol oil changes (gap of 10-12000 kms) on the xfer case and I have no symptoms now. Warranty valid till mid next year so ill try my best to break it on this last bottle of ravenol.

I thought I'd add my experience. I recently bought a new to me 2013 CTT with 21k miles. The car had a really annoying stutter on acceleration that felt like a confusing mix of misfire and transmission weirdness. My car was still under the TC warranty, but I decided to change the fluids first. As best I could tell, none of the driveline fluids had ever been changed.

I baselined everything: Fresh Motul 300 75/90 in the front diff, Motul 300 75/90 LS in the rear diff (for PTV), Motul DCTF in the transfer case.

The Motul DCTF made an immediate difference in the smoothness of the driving and improved a bit more over the course of a few hundred miles to the point of being pretty good. But then is seemed to get a bit worse as I could still feel a "stick/slip" when accelerating around tight corners again. So with only about 1000 miles on the fresh fluid, I used a giant syringe to extract 60ml of fluid from the transfer case and replace it with 60ml of Ford XL3 Friction Modifier (1/2 bottle). Magic -- the smoothness improved immediately and has only gotten smoother. BTW, the fluid I extracted (with less than 1000 miles) was already a dark gray color.

One final related change, I thought the transmission shifted a bit slow/rough. I did a pan drop and filter change on the transmission, and refilled with [6qts] of Idemitsu TLS-LV (WS) ATF in the transmission. After another 1000 miles of driving, this car feels like new. Very smooth and quick. I'm happy.

Replacing the TC fluid is so easy, that I'll make it an annual affair. I bought extra Motul DCTF, so I may try just replacing the old fluid next time without the Ford XL3 Friction Modifier. But if it acts up, I'll use the other half bottle I've got remaining to smooth it out. And after that, unless the plain DCTF works great, I'll probably switch to Ravenol since that's what's working for others. That said, the DCTF / XL3 mixture is working great for me now and is cheaper than the Ravenol.

Interesting. Thanks for sharing. I had my transmission fluid, differential fluid and transfer case fluid all changed at the same time all with Ravenol and the car shifts noticeably better. There is a just a slight hesitation still. I remember Deilenberger specifically not recommending using friction modifier. I can't remember his specific reasoning but so I just went with his recommendation. Please keep us informed. Especially if Motul alone is > Ravenol.

I just purchased a FVD Tune. After that, I give up.

so this TC issue pretty much is going to happen on all the 958 i assume, much like the shaft and hoses on the 955, how long of a repair typically?

dc1225

For me, varies from person to person, car to car and takes some tolerance. I did not notice during the test drive. It took me about 6 months as I was infatuated by the brand. I hated it at first but I am to a point where I can now understand how one would purchase another, thanks to Rennlist NOT Porsche as the stealership I go to are still busy trying to run from the fact. They still tell me not to change the TC oil. These are my 2 cents

dc1225

Besides that, I’ve got nothing bad to say but to me drivetrain is everything and I consider this to be such.

Depends on a lot of factors including driving style, where you log your miles (e.g. freeway is going to work the TC much less), engine power output, and probably even climate (e.g the theory is that water on the road makes it into the TC vent). I have 100k on my original TC, and it's just starting to a little jerky. First fluid change was at 80k. I took it into the dealer recently and they weren't even able to replicate any issues, so I'm still on it.

Hello all,

Not new to Porsche, but new to the Cayenne world, always wanted one so I purchased a 2018 Cayenne Platinum edition in pristine shape, 80,000 miles, came with a CPO warranty. My symptoms are unsmooth acceleration throughout all the gears, at low speeds such as going through a drive thru, or turning into my garage (90 degree left turn) loud clunking and bucking, almost embarrassing! Also when getting on it from a stop, when I let off in 3rd gear it stays revving and won't up shift, just stays screaming for a bit before shifting. I did read they are under warranty for 7 years/unlimited mileage. Just confirming my suspicions. Already called the Porsche dealer to have it looked at (closest dealer is 250 miles away) Service history does not show it has ever been replaced.

Sounds like transfer case.

Hi All,
For those Canadians in the group, I've had a very good experience with Porsche on this matter, so can confirm that Porsche Canada stands by the extended program on the Transfer Case. I bought my 2016 Cayenne S (CURA engine V6 twin turbo with 8 speed automatic) in February from a non-Porsche dealer with no factory warranty remaining (90K kms and 5 yrs old). Manufacture date was late 2016, so mid model year. Based on info in this thread that it's a seven year 'warranty', that would have given me until 2023 to make a claim.

1. Made appointment with Porsche Victoria (BC) to diagnose for jerkiness during acceleration mainly in 2nd/3rd gear, and intermittent grabbing of front/rear tires when cold driving slow at full left lock.
2. Took printouts of the most pertinent symptoms from this thread to the appointment.
3. Advised the service advisor that the symptoms I was experienced were an exact match for an highlighted set of symptoms on the printouts, and that I wanted them to strongly consider the transfer case as the cause. I further suggested that I stick around and go on the test drive with the mechanic.
4. The advisor immediately went to the shop and the foreman was available to do a test drive right away. On a five minute drive, he verified the jerkiness though he thought it wasn't too bad, maybe just starting out. I said that there were good days and bad days, not seemingly related to temperature or operating conditions.
5. I wasn't so sure when we got back from the drive whether the foreman was going to back the claim, he may have had to check with someone before tipping his hand, but the advisor talked to him in the shop... he immediately came back and said "it looks like we need to order you a new transfer case" (I screamed "Yippee" inside)
6. We scheduled a follow-on appointment, about 2 weeks later due to loaner availability.
7. I was in and out in 4 hours and got to drive a 2021 Macan around town (nice)
8. There was no charge at all including the loaner. The advisor verified that they had installed the newer vent-kitted transfer case which he said "completely solves the problem" (I didn't argue)
9. This was an excellent experience with Porsche Victoria, there were absolutely no questions asked. They just got on with it. They didn't verify if the program was 7 years, I was just happy that it was covered for five.

I just got this done yesterday, and the drive home seemed smooth. I'm about to go on a longer more diverse drive to confirm it's all better, and my car does not belong in the "POS" thread.

dc1225

I am not that surprised given that Canadians seem to be more friendly honest and upfront about things. Just from my personal experience.

I am getting to a point where I can see how a person would purchase another Cayenne after dealing with this. Not saying I would. Only because my driving habits changed. I now drive 60 miles/day in burbs to burbs vs 10 miles in big city.

Regardless, good to hear!
