2011 Cayenne Transfer case replaced
#256
NO. WRONG STUFF! (and yes - I'm yelling because that stuff will likely trash the transfer case.)

One bottle. It takes 850cc's.

so the dealer said it was not the TC and the noises were just the suspension settling. I replaced the TC fluid and it was black. I took it for a drive but still hear the walnuts cracking on left turn. I am going to let it run for a week or so and then change it again along with the front and rear diff fluids.

At that low mileage it's almost certainly a flaw in the TC - not wear that's requiring it to be replaced. An oil change would likely do nothing at all for it.

Glad I'm under warranty

Just relaying an experience I won't soon forget being proactive on X-fer case oil changes. After changing my engine oil & filter and the x-fer case oil for the 2nd time being proactive, I noticed a leak at the x-fer case drain plug. My case had a hairline crack at the plug. My two times in there exposed a weak area of the case. Remember, these are tapered plugs judicious use of thread sealant and torque wrench is required (which I utilized). So......I take my leaking car to Steve's European and we pull the case. We also pull the case apart so we can have the case welded. Arbor Motion welded the case and we added an epoxy patch over the weld for extra insurance. Dust seals, cir-clips, o-rings, etc. , were all replaced on re-assembly. While putting the case back in the truck, we found out that the truck had run over something prior to my purchase as we had to install new bolts for the cross members and case mounting brackets and use a pry bar to locate & straighten everything properly. From now on I will be siphoning my transfer case fluid from the top plug to change the fluid every 20K. Quite the $$$ journey. The only good thing found during this mess is that I have the new P/N case 95834101008 with a build date of 20.04.2015 which means it was replaced sometime after on my 12/2011 built 2012 Cayenne S. By the way when I drained the oil from the 1st change it was black and smelled after 5K. I will be siphoning once more during the next engine oil change which I maintain a 5K OCI. Using the -63 oil FYI. FWIW smooth as butter driving the truck even when making tight turns in the driveway.

That was exactly why I suggested "snug" - as in a slight resistance to turning using something like a 6" long wrench. A tapered plug IMHO is a dumb idea - but widely used for this sort of thing. A tapered plug into an aluminum case is even dumber. Using a torque wrench - especially a clicker type - at low torque settings is difficult to really master. Your arm tends to keep going for a bit even when you've heard the click and the length of the lever arm on the torque wrench means it's way easy to apply too much torque.. If I was to use one - I think I'd de-rate the setting (ie - if 10nm, make it 8nm.. and I forget what the torque on these is - mine were tightened to snug.)

Finally
Sorry I haven't updated this earlier, but after a month and a half I finally received my Cayenne back from the Porsche dealership outfitted with what appears to be a brand new transfer case. The only outside difference I can see is it now has a breather tube that runs up into the engine compartment. I am on vacation and have just traveled 800 miles without incident.

so a week of driving and the noise has definitely changed while taking the left turn. It is more subdued and not as noticeable but it is still there. Will give it another week and change the TC fluid again. Fingers crossed.
changed it a second time and it was black. Hopefully this time it's gone. Will report back

A quick update on my Cayenne. Now months after changing the fluid and 1,500 miles later, transfer case is still performing flawlessly in all conditions.
I mentioned in my build thread that earlier this week I went to Georgia to pick up some new wheels. The guy I'd been in contact with had the wheels/tires at his mechanic's shop. When he was helping me load the wheels, I noticed he had what seemed to be a 2011 or 2012 Cayenne Base. I inquired what problems it was having and if it was transfer case related. He explained that the truck was awaiting a transfer case replacement and the owner was deciding whether or not to incur the cost. The car had 70,000 miles and had the "clunk" sound throughout 3rd/4th gear.
I immediately let him on our fluid change secret as a remedy. He was skeptical, but took note of the exact Ravenol fluid that I used. I told him to get my number from the owner of the wheels if he had any questions. English was not his first language, so excuse the grammar, but last night I received this text message:
Add another quick fix to the list!
