Persist. Mine was reluctant at first also. Dunno why. Eventually it "took".
I reset mine to 0 when I changed the oil. I should check it again and see how it's changed. If you buy the ICarScan - to reset the TC oil use/wear numbers - the engine can't be running, but the ignition must be on. That fooled me for a bit. Got a communications error message when I went to reset it. Once I turned the engine off (leaving ignition on) - it reported "Success" - and the numbers were reset. I'd also love to see other people's numbers before changing -- especially anyone experiencing problems.
It's Don Eilenberger.. Basically http://www.obd2tool.com/goods-5052-Launch+X431+iCarScan+Bluetooth+Diagnostic+Scanner+for+Android.html - although I ordered mine over a year ago. I'm using the Android based software. I haven't heard from anyone trying to use the iPhone based software yet. As far as the Porsche version - whatever was the latest download.

Creating a new column - with two options: "Fluid Change" or "New XFerCase" That should clear things up a bit..
Steve - the list above is of Cayennes where new fluid was installed in the transfer case - and if it improved ("Remedy") operation. I'm sure your new TC has new fluid in it - but we can't attribute it's good behavior to the fluid alone.. :)
@958s - I'll be very interested in how the oil you now have in there looks after some use when you go to change it again. I'm giving thought to doing a second change on mine.
deilenberger replied to John Dee's topic in 92A (Cayenne, Cayenne Diesel, Cayenne S, Cayenne Turbo, Cayenne S Hybrid)John, you might do better posting this in the correct forum. Your Cayenne (assuming we're talking about one) is a 9PA (AKA 955) - and the forum for those models is: https://www.renntech.org/forums/forum/80-9pa-9pa1-cayenne-cayenne-s-cayenne-turbo-cayenne-turbo-s-my2003-2010/ Good luck!

I can't begin to imagine why changing the oil more frequently would be a problem. You may want to invest in a set of spare fill/drain plugs - just in case. The friction modifiers only "go away" with wear on the oil. They don't build up from changing the oil too much, they pretty much stay in suspension in the oil. My mechanic also suggested doing it every oil change (7,500 miles) - if the Ravenol appears to work well for 15,000 miles - I'll probably make that the transfer-case change interval, since I do oil about every 7,500 miles. Every other oil change. I don't know if I'd be as quick to do it that often with Porsche's $65 fluid though. (I'm value-conscious - ie - cheap.) BTW - Pastorom - thanks MUCH for telling the "rest of the story".. since yours was the only case so far where changing it on a higher-mileage transfer-case didn't improve it overall. Apparently the Redline wasn't the "right stuff.." Good on'ya!
deilenberger replied to lesgrossman's topic in 92A (Cayenne, Cayenne Diesel, Cayenne S, Cayenne Turbo, Cayenne S Hybrid)Dear bazza, This would require a Porsche specific code reader (Durametric, ICarScan) to diagnose. A WAG is the controller for the HVAC - but that's an expensive part to replace on a guess. It could also possibly be a failing switch. Do both sides do the same thing? Or only one side? With a code reader one could read the inputs from the switches into the module, and then read the output status going to the fan. And the stepper motor positions for the vents. At least with ICarScan I can. I haven't hooked up my Durametric to see if that's possible (mostly just from sheer laziness - it's way too easy to use the ICarScan.) So it's either buy a scan tool or visit the dealer time IMHO. I'm sure the HVAC module has to be coded to the vehicle, so no real avoiding that. Good luck and let us know how it works out please.

BTW - searching on the Shell oil turned up a number of hits with BMW forums. They have the same problems (and strangely enough, have ZF transfer cases that use the same oil we do. They also found that changing the oil often seems to solve most of the issue. http://www.bimmerfest.com/forums/showthread.php?p=8033580 and http://www.bmwfanatics.co.za/showthread.php?tid=17751
Porsche Oil: Looking at Porsche PN 000-043-305-63, it has no detailed spec's on compatibility or use specifications on the bottle. It's obviously made for our transfer cases since the quantity is 850cc's (the case capacity.) On the front it says: " Bezeichnung: getriebeöl" which translates to: Gearbox oil". and "Im geschlossenen originalbehälter 3 jahre verwendbar ab Herstelldatum: siehe Aufdruck" translates to: "In closed original container 3 years usable from date of manufacture: see imprint" On the warning label inside it gives a MDS listing (required by law): "Contains (1-tert-dodecylthio) propan, Ethoxylated anime, Calcium sulphonate, borated esters." then lots of health warnings. The first chemical ((1-tert-dodecylthio) propan) appears to be a lubricant additive "This substance is manufactured and/or imported in the European Economic Area in 100 - 1 000 tonnes per year. This substance is used in the following products: lubricants and greases and hydraulic fluids." The second chemical (Ethoxylated anime) is a surfactant (something that "wets" a surface - like detergent does for water). The 3rd chemical (Calcium sulphonate) is something fairly new according to a Google search. It's an oil/grease additive that gives rust protection and works as an extreme pressure additive at the same time. The final chemical "Borate esters possess friction-reducing, antiwear, and anti-oxidant characteristics when blended in lubricating oils." Not super radical chemistry, but the one "new" chemical is interesting since it specifically is used to protect against rust while still working as an anti-wear extreme pressure lubricant (extreme pressure means "metal to metal" - it forms a barrier preventing this contact - ideal in this sort of clutch). Fuchs Titan ATF 5005: This oil is suggested as a direct replacement for the older Porsche oil: 000-043-301-36-M846. It is shown om Fuch's website as an automatic transmission oil, basically a DEXRON III type oil.. The bottle has no MDS listing on it, so the chemical composition is unknown. It is supposed to meet the Shell TF-0870 oil specification. It is widely sold as being for all Cayenne transfer cases. In looking at Fuch's own website - where they have a product selector: http://fuchs-eu.lubricantadvisor.com/advice.aspx?lang=eng&type=91be4020af03306d78b8184be618df13 - they list a different ATF for use in the transfer case: TITAN ATF 7134 FE - which raises an interesting conundrum. The 7134 FE is a recently developed lubricant made for Mercedes automatic transmissions that apparently were experiencing shift problems with standard ATF lubricants like ATF-5005. https://www.fuchs.com/uk/en/products/product-program/automotive-lubricants/#gear-oils Most importantly - I could find no Fuchs approval of the 5005 oil in our transfer cases. It might just be an older recommendation that was superseded by the 7134-FE recommendation, The change in recommendation might almost makes me think that Fuch's is the OE supplier for Porsche, and that Fuchs-5005 = 000-043-301-36, and Fuchs 7134 FE = 000-043-305-63. The reason for the "almost" is twofold: There are warnings that this fluid is not compatible with red color transmission fluids, and the fluid is blue. The new Porsche fluid is amber. RAVENOL Transfer Fluid TF-0870: I don't have any bottles of this - so I can't say if there is a MDS sheet under the back label. Ravelol US gives this description: "RAVENOL Transfer Fluid TF-0870 is a fully synthetic gear lubricant designed specifically for the latest generation of electronically controlled active transfer cases. RAVENOL Transfer Fluid TF-0870 is formulated with fully synthetic base oils (PAO) combined with special additives and inhibition. RAVENOL Transfer Fluid TF-0870 ensures optimum power transfer and ultimate reliability." They also specifically list it as recommended for the Cayenne transfer case and equivalent to Porsche 000-043-301-36. I think this is a safe bet if you want to use other than the Porsche overpriced oil. It would certainly work as a flush oil with a final change to the more expensive Porsche 000-043-305-63 fluid. Enough on oil. Chris - I'll be very interested to hear how your latest change holds up.
Chris - it might be a fun project to try to find a barbed nipple that could be screwed into the case in place of the drain plug, then route a line from that to a small hydraulic pump and pass that through a filter - and then back into the fill port. Circulate the fluid and try to trap the suspended particles in the filter, and let the circulating oil wash any more out. Only problem I can see is it wouldn't get fluid up around where the clutch assembly is (up at the top of the case). Probably work just as effectively to do another change of fluid in 1,000 miles or so. As long as you're not using the $65 Porsche stuff it isn't too painful to dump lightly used fluid. I think I'll do some more fluid research. See who makes what for transfer cases.. I have a liter of the Fuchs oil sitting on my shelf. That was $15 or so. Have to spend some time seeing what approvals it has and how those might transfer to other oils.
On the other forum where this topic has been active (http://www.6speedonline.com/forums/cayenne-958/287782-2011-cayenne-transfer-case-replaced.html) there has been some discussion of getting a base virgin sample of oil tested by Blackstone Labs, then getting our samples of used oil tested to see what changed. Problem we have is I'm a bit cheapish - and don't feel like paying the $60 or so it would cost to buy a bottle of the original fill oil that Porsche used just to have the test done on it. That oil had a PN of 000-043-301-36. If anyone has any of that oil - unused - perhaps the remainder from doing a change and having some left over - I hope I could talk Blackstone into doing a free baseline run that we could compare our used samples to - and get some idea of what's going on. If that happens - I might also send along the bit of remaining oil from the new PN Porsche spec fluid (that ends in '63") so we can see what (if anything) changed between the two fluids. Anyone?
