My Cayenne S Diesel had the transfer box replaced a couple of years ago, but it failed again after around 25,000 miles or so. It was replaced again earlier this year and I was told that the box is now a new design with completely new internals, and so the problem shouldn't re-occur - I will be maintaining the warranty just in case!

Thanks for that jbm. I will definitely be asking when I collect on Tuesday if my replacement is the new design!

I'm thinking of buying a diesel S with about 60k miles. What sort of cost is it if the tf box packs up? From what I have read this isn't necessarily a mileage issue,  or is it? I live in the countryside so going through water, sometimes quite deep, is not uncommon.
Thanks if you can advise

Hi John
I had a Macan diesel for just over two years it had done approx 16000 miles transfer box went on mine. Luckily it was still under warranty so free!!however i think you will be looking at around the £2000.00 for a replacement if not a touch more maybe. Im sure if you rang Dealership they would give you an estimate.

Yes suspect mine needs replacing after 6 months ownership, 2016 GTS, 26,500 miles. Booked in for recall and transfer box issue on the 27th July.

I have a 2016 Cayenne S Diesel but no warranty. it has 43 k kms on it and i observe some juddering while turning sharply and very slowly. on high speeds, not sure or lurching (didnt see the rpm gauge) but it feels like thuds on very high acceleration from 50 - 100 kph. What i found out about this issue on other forums is that replacing TC oil solves the issue. Will try that in next few days and report with the outcome.
Another transfer box casualty. My 2017 Cayenne S Diesel is currently getting a replacement under warranty. Just 3 years old and only 23k miles. Does anyone know if it's just a straightforward replacement with same or is there an improved item that solves the problem so it doesn't recur.

If you have a Macan or Cayenne. which is out of warranty and displaying transfer case problems try the following fix, which worked for me on my 2013 Cayenne 4.2S Diesel. Purchase new transfer case fill and drain plugs from Porsche (about £40 for both which seems crazy for threaded plugs but they do come with Loctite on the threads)! Next, you need to purchase some good quality transfer case fluid. Do not get the Porsche fluid as my experience suggests this may not be up to scratch and contributes to the problems. The one I used is RAVENOL DTF-1 Transfer Fluid (TF-0870) from Ravenol Direct It costs about £20 per litre at the time of writing. Mine took just over a litre until it was full so buy 2.
When I drained the old fluid out of mine at 79,000 miles after experiencing juddering from the transfer box, it was a thin in consistency and almost black in colour proving that it had degraded either through wear, moisture ingress or a combination of the two. When replacing the drain and fill plugs you must be very careful not to overtighten these as the transfer case is alloy and will crack if you overtighten! You will need a torque wrench and tighten to no more than 15ft /lb or 20Nm (don't get these the wrong way around)! Once you have replaced the fluid it is advisable to get the transfer case wear indicator reset (a Porsche Independent Specialist which has PIWIS will be able to do this for you).
If your car has air suspension put it in the highest setting and you should be able to crawl under without having to jack up the vehicle. 
My Cayenne has now done nearly 20,000 miles since the transfer fluid change with no slipping or juddering from the transfer box. 
I would suggest trying this possible fix first, before going to the considerable expense of a new transfer box.

I've heard of owners fitting Land Rover wading kit breather pipes to the Macan to bring the pipe up in to the engine bay
