    Be aware the most dealer will not share the service records for the vehicle because they legally belong to the previous owner(s), and the dealers are uninclined to track them down and get a legal release.

    A cooler on the return line from the rack to the pump will probably help.

    Welcome to RennTech And congrats on the new (to you) Porsche. Probably one of the most detailed sources of information on this engine is Flat Six Innovations, which is Jake Raby's shop.

    I agree with millerchris85. After all the work and money poured into my CTT it’s eh now and I’d have been better served tuning up my 996TT. If you really must have a sporty drive in a Cayenne then I suggest looking after a 958 GTS, Turbo or Turbo S and having someone tuned them to your liking. Be forewarned though you will wear through ancillaries (brakes, axles, tensioners, etc...) much faster depending on how much and how hard you drive

    FWIW if you are looking for a sportier drive, you probably have the wrong car. I did put secondary cat deletes on mine and am very happy with the results, but it is just a bit more noise and response. But it drives and handles like the 5000lb+ SUV that it is, albeit with plenty of grunt. It remains quiet and comfortable which is great for passengers and road trips. Plus I want to keep the rear diff and trans intact as long as possible. Lastly, beware getting a cheap tune; you really want to go with someone that will double check your fueling and AFR's before and after. Unless it is a conservative off-the-shelf tune, I would not put anything on a car that hasn't been pressure tested and with a wideband AFR for logs before/after.

    I pulled up the carpets. Under the driver carpet I could see salt water deposits from the winter. There was a thick black line running from Terminal 15 that had a very corroded spice to three other large black lines. I ended up replacing about 2.5 feet of wire as the wire inside had turned black, I finally found shinny copper just under the dash. I then reset the car electrical -- removed the battery cables, connected them for 15 minutes they left them unconnected for 15 minutes. Next I reset the panoramic limits (turned it to the A position and tilted the dial for five seconds then held it for ~20sec until it ran through the reset). Now my panoramic roof works!! first time in over a year. I will now see if it fixed the other intermittent electrical problems I have. Thanks everyone for their input!!!!!!

    I may have found my solution. After looking at this PelicanParts tutorial on removing the driver's side door panel, it appears that the 16 pin female connector actually connects to a connector inside the door, and the 10 pin connector comes from a line inside the door to that mirror switch in the small panel at the top of the door. Here is a link to the Pelican tutorial: Porsche Cayenne Front Door Panel Removal | 2003-2008 | Pelican Parts DIY Maintenance Article WWW.PELICANPARTS.COM There are quite a few projects that reside behind your'front door panels. Figure out how to take them off the right way!

    You need to understand something about pelican, they have a long history of stretching the truth, particularly about what is factory and what isn't.. Yes, a Shell division makes the fluid for Porsche, but it is made to Porsche specs for Porsche exclusively, and not available through any other source but Porsche. So whatever they sold you may be made by Shell, but if it isn't bearing a Porsche label and in Porsche packaging, it is not the same thing.

    Redo this, you have no idea what quality the other oil is, while the Porsche product is well known.

    If you add the 997 GT3 master cylinder (27mm bore) to the 996 in order for the psm/abs to work perfectly and not throw any codes you will need to install a brake bias adjuster in line between the rear master port and the psm pump, it needs to see about 7% reduction in pressure or it will throw a psm/abs code and shut down the system. Note the 997 gt3 master has both ports 12mm bubble flair, unlike the 996 masters that use 12mm front, 10mm rear so you will have to make a custom line or a adapter (they suck) Anyway it gives you a rock hard pedal with the 997 or bigger brakes and all works as it should

    And to answer your question, updating firmware does not require new maps. Porsche updated me from 1.44 to FW 1.47 for free while I waited. Took like 10 minutes. This is when I was told that while the newer PCM 3.0 FW exists, 1.47 is the newest for the Cayenne. 2009 Cayenne S

    I've attached 2 plumbing schematics for the air suspension system. The first is for the Touareg, the second for the Cayenne. I'm assuming the aftermarket compressor you have may be like the one for the Touareg which did not have the tyre filling feature. If that is the case then you can see the tyre filling plumbing is not available on that compressor, and is also fitted with some extra check valves which could be causing your issue. The tyre filling connection is shown as number 8 on the Cayenne diagram, and is missing from the Touareg version.

    SO - Porsche advised each diff needed 0.9 Ltr of oil so got myself 2 Ltr of Porsche Diff Oil and took to my local garage to get the oils changed in my 2004 Cayenne V6. Drained the back one and filled with 1.4 Ltrs of the oil. All good. BUT WAIT!! That means I only have 0.6 Ltrs left for the front diff! And guess what at least 0.8Ltr drained out the front so I won't have enough Porsche Oil 😞 So the garage said its just 75w90 gear oil and that they had some they'd use on the front. problem is it was RED oil and Porsche was yellow. So we couldn't mix the oils - instead they put in the full 0.9 Ltr of the RED non Porsche oil. NOW - I'm kinda freaking - IS that RED oil OK to use as it is 75w90 gear oil or should I get it out ASAP and replace?? Ive attached a photo so you can see what the oil the garage used is Please someone put my mind at rest 🙂
