  1. I have a 2004 CTT and its been very cold lately here in Pittsburgh. Recently my driver door will close, but the car doesn't recognize it as being close. The dash warning continually stays on no matter what I try to do. This is very annoying as the ambient lights stay on in the car and it usually won't lock when I get out. It was freezing and then the last two days it has been getting warmer, but the problem persists. 

     

    Any ideas? 

  2. I also agree. Porsche Mx has been extended too far. They've went cheap with many things (Plastic Coolant pipes, center support bearing rubber isolation, etc...).  Some great design/engineering but substandard materials used on some things. Now with that said I love my Pig, but I do Mx in half or less of the Porsche interval because I'm not sure how long I'm going to keep it and I'd rather cut the wear. No I don't do 3500mile oil changes, that's stupid and causes more wear with the extra dry startups but I do 8K oil changes. I also changed my tranny fluid at 50K and will do it again around 90~100K. Although I do use Redline fluids for the most part, 5w-40 engine oil, D4 ATF in the tranny, also their Gear oil in the Diffs. 2003 & 2004's had more valve body problems than the 2005-on models. Supposedly it isn't just that there older but that the Valvebody was changed. There is also a TSB on the ATF thermostat for '03 & '04 Cayenne's which caused some trannies to get too hot, also a fluid change from the original fluid (better fluid?).

    Also, the shifting can be affected by a vacuum leak depending on how large. All of the cheap plastic vacuum & PVC lines on the Cayenne get very brittle after a few years. This is affected by age, miles, climate. My '06CTTS w/74K that I just replaced the plastic Tee's on last month has a few just split with hardly any movement so I replace most all of them. At least the ones that were difficult to get at or damaged. Get that Lean condition fixed soon, Lean is never good, especially on a Turbocharged engine.

     

     

    This is what I was touching on in my OP. How many lines are there and are there any special names for them, or just CTT vacuum lines? Ill try those first and a fluid change then ill bite the bullet and do the valve body. 

  3. 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.

     

     

    So what you are saying is that I am just in denial of the valve body? But are you saying you changed the fluid in the tranny and you for buttery smooth shifting? Or the valve body? 

     

    Have you heard of anyone using any other fluids with better luck? 

     

    How much to rebuild the valve body? 

     

    Thanks for your help, its a shame they sold these cars with such expensive problems. Guess thats owning a Porsche though.

  4. These answers have been covered many times here before.

    I know this question has been asked before, but everytime I have looked i see everyone suggesting a valve body, but have briefly heard people solving shifting problems other ways. I am here looking for a more in depth explanation of other ways to solve these problems. 

     

    I know the tranny fluid has been answered a million times and I probably shouldn't have asked that. Just wanted to see other options than Porsche recommend as people have also reported improved shifting from better fluids. Just wanted to hear validity on that matter. 

  5. As the title reads, my Cayenne is shifting from gears 2-3 horribly under heavy acceleration and in the higher gears a bit and slow on downshifts. In auto is almost not there but in manual it is more prevalent. 

     

    I know the valve body is everyones first guess but recently i have been doing a little more exploring to see what my options are before diving into a $2,500 repair. I have read that people have gone under their engine covers and replaced a thin plastic pipe near the throttle body that has for whatever reason, fixed the shifting. Also people have changed filter and fluids and have reported there tranny's were shifting great again.

     

    I went to the P dealer for what was a boost leak and they ran the codes as my PSM light was on and they got P2189, lean at idle bank 2 and P2281 Throttle Plate. Said nothing about the transmission or valve body. 

     

    Basically my question is what do people do to avoid the valve body right away, even its just a little better, it would be worth it in my opinion. And what is that little plastic pipe called? My Cayenne is at 97k and this is really the only real problem on it. 

     

    Also if I'm gonna change the tranny fluid, what fluid should I use & how much & what filter? 

     

    Car is a 2004 Cayenne Turbo.

  6. Driving down the highway at 75mph in the CTT and all of the sudden the car almost violently loses power and I have nothing when I hit the pedal, the car downshifts every gear to the redline and i pull over. The check engine light comes on.

    I turn the car on and off and have power and cruise away fine, CEL still on, then 5mls later the PSM light comes on. What is going on?

    Normally for some reason when I'm on longer highway drivers, the PSM light always comes on and stays on for a couple days then goes away. Why does it do this? Winters coming and I don't wanna be driving around with no traction control in the snow.

    Any help would be appreciated Thanks.

  7. Hey y'all, got some more questions...

    1. My car clunks. Only when slowing down, and below 10 mph. It's a very audible sound. Sounds like something disconnecting from something. And I don't think that it happens on a downshift. And if also happens maybe 10% of the time.

    2. My gearshifts from 2nd to 3rd are brutal under full acceleration, only in Manual. Like the car jumps and it also is very worrying. Doesn't really happen in auto mode. Any idea? Obviously it is tranny related, but would it is?

    Thanks.

  8. Well just got back from North Scottsdale Porsche. I did pull the old battery and the ground terminal was badly corroded. Purchased an Moll battery $436 (ouch) and an new cable is on the way from Sonnen. Looks like the pervious owner had a Touareg Battery in her. Not sure when it was replaced but I am hopeful this will solve my problems for years to come.

    Wow they saw you coming!! $450 for a battery, over my dead body! I payed $130 for a decent one and have had no problems. But, like you before I pulled the battery I had a slew of problems, all smalls things. But they are all gone!

  9. Hey guys I drive a 2004 Cayenne Turbo with 90k on it and I am looking at new vehicles. I have decided I want another Cayenne, but can't decide if I want to get into a face lifted model for the extra money.

    I love the looks of the face lifted version but I am weary of other differences? Is there any noticeable performance gains from the 4.8 and 500hp? And is the ride any more controlled than in a 2003-2006 model?

    Just wanted to hear everyone options especially from face lifted owners!! Thanks.
