An independent Transmission shop or independent mechanic would be appropriate. It’s been quite a few years, but as I remember the rebuilt unit came with very detailed instructions. Frankly, the replacement was very straight forward. 

This has been a pretty well covered topic. Try a search of it on the forum you’ll find quite a bit of detail.

Best,

Had the same symptoms and sound on my outer CV on my old CTT. replaced CV, noise disappeared until the other side went about 4 months later.

Steering Rack will need to be replaced my friend.... There is a known issue re this. Google: faulty steering rack, cayenne and won't start. I spent thousands chasing this on my first CTT several years ago before it was a more common issue.

Best to you.

FYI - The "check is in the mail." I have not received mine yet, but one in our club did yesterday.

Greetings!

Haven't been on the 9PA forum in quite some time. I've been told that the settlement payments are finally going to be distributed. I've heard we should have them by 2/8/2016. Has anyone one else gotten this message? Looking to close out the books on the old 2003 CTT.

Cheers!

Glad you're back on the road!

We have one in our club and it runs quite nice.  We've joked a bit about missing the guys at the local P service dept, because we both used to have original year CTT's (2003) he now has the 957 Turbo and I have the 958 Turbo. 

I'm not aware of any reason to stay away from the 957. If it has PDCC you will enjoy it even more.

Cheers!

Well you have a problem and now you're 99% sure what it is. 

When this happened to me all we had was "change the batteries." Played around like you have and got really frustrated... But was always appreciative of people taking the time to provide some guidance on this site. 3 years ago no one had experienced this issue on this board. So on top of the expense of the fix and all of the batteries and all the other DIY exercise I went through I also spent over $2K JUST for diagnosis.

You really don't have much of a choice. Your 2004CTT is nearly worthless as it sits. Fix it - keep it, fix it - sell it, or part it out - sell it.

Reference post #10 in this chain. 

I had put together a pretty good bit of research. Here are some of what I dug up when arguing to reduce some of the diagnostic $$$ with the dealer.

Best of luck to you.

Not fun.... The good news is you can save a ton of diagnostic $$$. That switch in the column sure sounds like it's failing/failed.

I wouldn't drive it that way, I'm guessing it's a stuck open thermostat, but ???? Not a common Cayenne issue I'm aware of.

On my M5 I had a stuck open thermostat on the way in to my office with near Identical symptoms and then it became a stuck shut thermostat on the way home and it was a disaster - 7 mile commute.

Sure sounds like a thermostat that is stuck open. 

Sounds interesting.....

Just know though that you can blink and easily spend 3-4 K on a well maintained 05 CTT let alone one that has sat for 2 years. I say this because I had a well maintained first generation CTT from original purchase for over 10 years. If you can double that and feel comfortable then you'll be fine.

Cheers!

This may be of some help:

One last piece from my end. Here were the notes the Porsche tech left in the invoice:

"Vehicle will not start due to a faulty EVL. The vehicle will not start and the steering wheel will not fully unlock. Performed tests of the wiring for the EVL and the ignition module - ok. Checked the connection of the KESSY module, EVL and ignition switch - ok. Back probed the KESSY module and checked the voltage during function of vehicle key. The KESSY is not seeing an unlock signal for the EVL and in turn is keeping terminal 15 off. EVL can not be replaced on its own, quote a steering column for this vehicle."

I'd take it in my friend.

There is nothing in the steering rack that would cause this issue but the control module that is part of the steering column will. The Porsche scan tool can access certain control module without the ignition key operating so I recommend you take it to the dealer but be sure the battery is fully charged and not the source of the problem. I've only seen this fault occur on the 2003 to early 2005 vehicles.

Actually wvicary is absolutely correct. After reviewing the MANY service invoices for the old 2003 CTT I see that it was the entire "steering column comp" P955-347-007-19 that was the root of this issue for me, in my case the rack was replaced as well. In my notes from that repair on 10/12/2012 the tech had explained exactly what I have stated, but referred to it as the " sensor in the rack." I never checked the documentation to clarify at the time. It was a sensor in the column module, which is embedded in the column itself. Of course they did replace the steering rack as well, but after review that is just because it was faulty. 

This was an absolute nightmare and the beginning of the end for that car and me.... I am very competent DIY mech, but the issue with this and many of the subsequent issues I had after 135K miles were all module/wiring/electronic issues that with the complexity of the multiple systems and their interaction with each other were really far beyond DIY. I did buy a new one in 2013 so I obviously loved the car more than the pain.

The biggest $$$ was diagnosis because PIWIS didn't work either.... It was just over $4000 all in. 

No idea on Indy.

It took them FOREVER to figure out.

Steering rack!

Had this same issue a couple of years ago my friend. It's in the forum. Spent weeks at the Dealer before it was resolved. There is a sensor in the rack that goes out.... It is very early in the progression to "energize" the ignition. You will not get a Durametric reading because the system is not on yet. I suspect you have a soft brake pedal and cannot get the car out of park.

Mine was a head gasket. Coolant never boiled.

It's a bit strange though that your "coolant warning came on" as in my experience this is an indicator of coolant level being low. If so, where'd it go? Ground? Engine - oil? And, you have oil in the coolant.....

So complete a leak down test, but to be very frank running a leak down test is the easy part, correctly diagnosing the issue on a Cayenne V8 is a little more of an art. Check your compression as well.

Also, you may think about making a donation to this forum.

Unfortunately this has happened before:

My 03 CTT had this issue and it was a head gasket, but others in my club have as well and in 2 of the 3 it was "buy a new car time" because of the cost of repair. You really need a leak down test done by a knowledgable mechanic for proper diagnosis.

I'm saying after 3 fluid changes I Finally changed the valve body (rebuilt) and this issue was fixed for good.

It is a shame that a car such as the CTT has a high cost for maintenance, but look at it this way. My original CTT was 113K in 2003 when I waited 6 months for it to arrive, I was happy to get it because there was nothing as powerful, convenient and exclusive at the time.

Now anyone with 15K in their pocket can pick up a used one that still looks and runs pretty darn good. It makes me chuckle a little when someone who picked up a 100K car for a small fraction of the price complains that they're a little more expensive to work on....

I couldn't resist.... It is a Porsche though!

google: warner aisin transmission problem shifts

It's first a design issue that impacts the valve body of the transmission (MANY warner aisin transmissions) that is seriously accelerated by a (IMHO) ridiculous lack of maintenance required by Porsche. This fluid should be changed every 50K.....

My first CTT's been gone for some time now, but I went through the denial on the Valve Body as well. I changed the fluid three times. At first it would be better for a little while and then it would come back. It started for me at about 90K. Once it was change BTW I drove it until I sold it at 175K with buttery smooth shifting.

It's been mentioned over and over again, but the valve body issue does not throw codes. Its just gets worse and worse. The solenoids in your valve body are getting stuck in metal particulates and aren't actuating properly. Eventually you will have intermittent shift issues so hard it will feel as though the bottom is coming out of your car. If you want some reinforcement on this thought process go to your local VW dealer and talk to a tech about their same year T-Regs. They sold a ton of these and they are all high mile cars now that have problems with harsh shifting. Same transmission - Valve body. 

I've helped trade out 18 of these for other CTT's in our club, we can do it now in about 30 minutes. Have or complete a solenoid rebuild on your CTT's valve body, change fluid, feel like you have a new car. There is no short cut to this.

Fluid is Mobil ATF 3309, buy a case, you won't use it all but you'll get a deal online by doing so. Use oem trans filter and rubber gasket. Reset the adaptive learning on the Trans with a Durametric.

Super all too common problem. This should help:

You're going to need a couple "special tools."
