Loren, if you have a Durametric or IcarScan tool you can read the transmission oil temperature directly with them. I believe that's how a dealer would do it..

Finally got all the tools(pins and triple square sockets) and parts. Started in and had a issue removing the wear indicator. Ended up breaking the back side of the wear indicator. Looks like I have to order a set of those. Is there a trick to removing these? I took my needle nose and squeeze the spring clips together with no success. Tried taking the screwdriver to help and that's when I cracked the backside of it. Any tips would be great. Thanks 

One of my laws: "You'll never need the part you have.." - meaning if you'd bought the wear sensor before starting the job, the old ones would have come out just fine. Had yours indicated the pads were worn? It looks as if once they touch the rotor surface and the plastic surrounding the actual sensor starts being worn away - they become much more difficult to remove intact. Or to install intact.  They're the cheap part of the job - I just order them when I decide to do the job. Dunno what I'll eventually do with the old sensors that came out just fine and are sitting on the shelf.. :)  I'm sure I'll never need them.

Dang...must of struck a nerve. The word is "excessive" was probably incorrect...and "redundant" is better,I agree there. It's not about the price of $32 being excessive,but more for a tool that I'll use once every 30k miles(4 years) then they maybe "excessive". Who knows this thing may even get bought back by VW. 

 

BTW..do u have a set of pins I can borrow? Lol. 

If you want to swing by and pick them up in NJ.. sure.

BTW - these sort of special tools - typically have a resale value when you get rid of the vehicle of about 75-80% of their new price. BTDT with lots of BMW special tools for their cars and the bikes. If I'm not using them - I'll post them on a forum FS list and they're typically gone in a day or two.  There are a number of BMW valve shim kits that increased in price so much while I owned them that I made a profit selling them, had a bidding war going on.

Thank u very much. The pins did seem excessive. Does anyone know the torque specs for when I re-assemble?

$32 is excessive?  If you drop one of the calipers and rip the brake line out - the cost will far exceed $32. If you drop a caliper, rip the brake line out and it ends up on your toe - the cost will far exceed $32.  You're going to save $300-500 over visiting a dealership.. and $32 is excessive?

Reread what he said: "I found the pins somewhat redundant if you have another pair of hands to help" - do you have another set of skilled hands around?

Does the icarsoft allow you to activate (turn on) components? If so - try turning the fan on at various speeds and see what happens, then report back. The most frequent failure appears to be the blower itself - and it looks like a royal PITA to get to, some fairly heavy duty interior disassembly required.

I went looking for it in the wiring diagrams - and nothing in the battery-power circuits showed a manually operated switch, so it must be somewhere else..

REALLY interesting. I never noticed the switch. I was easily able to see it by moving the seat all the way back and then popping open the little cover. Since I sometimes leave the P!G for a month or so at a time in the garage (out playing/travelling on my motorcycle) putting it in the storage mode has some real appeal. Plus it makes for a great theft deterrent.

Cool beans!

I have no idea where there is a switch that you mention. Can you take a photo of it?  If it requires removing the seat - it's not happening.

Have you done an entire system scan with the ICarScan? That should pinpoint where any faults are recorded that might cause the message you're seeing. It is worth doing a system disconnect/reconnect - if the voltage dropped low enough when you were in the process of swapping batteries that might account for the message you see. It may be a residual that clears if the car boots up with a fully charged battery.

There is no "register" the battery on a Cayenne. BTDT spent a lot of time researching it. If you ask a dealer's service department the response will be "huh?" - they simply replace them. There is info in the Gateway on what battery was installed at the factory - but there isn't a tool capable of changing that information or adding to it. I tried Durametric, ICarScan (which looks like it has the ability - but if you go to write it to the Gateway is doesn't "take"), Snap-On and several other tools.  Then I noticed that Porsche actually changes the charge characteristics according to how you're driving the vehicle. If you have it in non-sport mode, charge voltage is limited to around 13.6V. If you press the SPORT button, that voltage will immediately increase 1V. Doesn't matter what gear, what engine speed. The reason for this is fuel economy. They want to increase the corporate fuel economy rating for the EPA - which saves them gas-guzzler money, so they limit the load the alternator will put on the engine when you're in normal mode. Since fuel economy isn't measured in "Sport" mode - they can unlimit the load and allow for full charging.

As far as your problem - I suspect your battery is only partially charged. Before installing any new battery it should sit overnight on a smart-charger until the charger indicates it's fully charged. A battery that doesn't have this done will likely never be capable of full CCA rating. What you might try doing is disconnecting the battery and charging it in place. Hopefully you DID connect up the vent tube to the new battery (I have the same battery in my '11 CTT..)  Charge it up overnight and then reconnect it. See if the fault message goes away. The fact that the ICarScan couldn't communicate with your ECU makes me think the vehicle voltage is low enough that the modules have triggered low-voltage protection mode. They shut themselves down to prevent burning themselves out due to low voltage.

You can display a voltmeter on the multi-display on the dash. It would be interesting to observe that.

Don: Thank you, I have a X431 R and a Durametric , looks like I may need another electronic gadget. I would like to see the service level on my Cayenne;s transfer case lube prior to changing it.

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.

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.. :) I realize my original description wasn't clear - so I'll add a column.

Creating a new column - with two options:

"Fluid Change" or "New XFerCase"    That should clear things up a bit..

Mine was a "Good Will" replacement by Porsche through my dealer at no cost to me.  yes, they put the new vent hose in too.

 

Mine was not a failure, but it was making the same noises that others have reported here.  It is silky smooth now.

@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.

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/

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!

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"

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.
