Transfer case
#1351
I think there is a value you can read from ODB / PIWIS that is something to do with the wear or age. Not sure if it is simply a counter or if there is a sensor of some type in the transfer case. Whatever it is, is doesn't seemed to have saved a single failure!

Hi all, I have 2011 Cayenne S at 216K KM here in The Netherlands, I've been having issues about the TC and jerky shifting, my local dealer inspected and mentioned about possible TC replacement. Can I have this replacement under warranty by any chance? Thanks in advance. Will keep here updated.
Edit: they've changed the transfer case oil a week ago but didn't worked.

According to this forum.. I've seen that there is 10 year warranty for the transfer case from date of first purchase. So you might be just past it. But worth asking Porsche to see if they'll cover it anyway. They may decide to at least pay for the transfer case and you pay for labor.

- Cayenne – Model Year 2011 Through Model Year 2014 – Warranty Extended to 10 Years With Unlimited Mileage
- Cayenne – Model Year 2015 Through Model Year 2018 – Warranty Extended to 7 Years With Unlimited Mileage
- Macan – Model Year 2014 Through Model Year 2018 – Warranty Extended to 7 Years With Unlimited Mileage
This is from your in service/delivery date. Its likely with a 2021 that your warranty has expired at this point.

Somewhat naive question.... If a vehicle has yet to present symptoms of a failing transfer case and has never had its transfer case oil changed in 11 years and 86K miles, would changing the oil from now on prevent a failure? Is changing the transfer case oil on a yearly/10K miles basis a "guarantee" to prevent from it failing? Or is this new maintenance schedule a "delay of the inevitable" i.e.- there is no escaping the fact that the transfer case will fail. This is especially important to those of us who have vehicles that are not covered under the extended warranty.

I'm waiting for some political situation to calm down (Panama) in order to finalize the purchase of a 2011 CTT and have budgeted ±$6K to bring it up to spec with all of the consumables/oils/filters replaced, but was left wondering if the TC issue is something that could be prevented by doing frequent TC oil changes or if it's a "time bomb" like the 957s and their cardan shafts/coolant pipes (it's a matter of when they fail, not if they fail...).

i would say that frequent changing of the TC oil will probably minimize any apparent issues and prolong the life but it isn't a fail safe for it never going bad, if that makes sense.

The effectiveness of changing the transfer case fluid depends on which transfer case you have, and the type of driving you do.
The newest transfer cases with the reinforced clutch plates which are not failing, and don't need frequent oil changes like the older versions. In the older transfer cases, the clutch plates break down and fill the oil with clutch debris which will further accelerate the clutch wear over time. In general, if you freeway drive/cruise all the time, then frequent changes aren't needed as often as if you do lots of stop and go driving. Older transfer cases driven constantly in stop and go driving, can benefit from oil changes as frequently as every 3k miles. But if you're freeway cruising all the time, then an oil change might be needed in 50k-80k miles!
