    You should be able to activate the cam units one at a time with the Durametric software, which will cause the cam timing display to change and impact how the care idles.

    Are you getting these codes while testing the car while it is not running? Reason I ask is that you are possibly are getting the CAN Bus codes because the system is timing out and going to sleep on you. Try clearing all of the codes, running the car, and then rechecking them, but this time if you turn the car off, leave the four way flashers on, which will keep the car from timing out and going to sleep on you.

    You have multiple cylinder misfires, a common problem on these vehicles when they develop coil pack issues. I would plan on pulling the coils and plugs with an eye towards replacing several.

    No. With the engine running, and the trans in gear, the front pump is running at full pressure and everything is full. One further query JFP, how important is it to drain all fluid from the system ie. from cooling lines etc? The only way to get all the fluid out of the trans is to take it out of the car and then take it apart, which is ridiculous for obvious reasons. There are no external ATF lines on these transmissions, the cooler is mounted to the side of the trans and engine coolant is run to it. You can get most (80-85% of what is not in the converter) of the ATF out of the trans by a simple gravity drain, but this is still only about half the total system capacity, the rest of which remains trapped inside valve body passages, clutch packs, etc.; with the lions share of the remaining fluid trapped inside the torque converter itself. Because of this retention of old fluid, it is a good idea to shorten the maintenance cycle from the factory 90K miles to something in the range of 40K miles for a street car, less for one that is tracked regularly. For a trans that has fluid in very bad shape, multiple fill, run, and drains remains the best option to get as much out as is possible.

    The first three look about average, the next two however look a tad on the rich side. I would agree with Ahsai, get the fuel trims read and also look for any stored or pending misfire codes, which will point to specific cylinders.

    Call board sponsor Sunset Porsche in Beaverton OR; they should be able to help you.

    Simple: The Cayenne is the only Porsche model that uses VW based control technology, none of the other models do this. Find a 996 and try Ross-Tech system and you will see why even Ross-Tech recommends the Durametric system for Porsches.

    Take a word of advice from someone that does these retrofits for a living: Don't try to reinvent the wheel, buy the LN kit and install it. You will be happy that you did. I do appreciate the advice. You certainly have more experience than I. However, I spent a great deal of time researching the topic on this and other forums and don't want to have yet another thread full of opinions about the IMS. Suffice it to say, I have my reasons for going to route I chose. Now, I just need to find the **** part! Then you face a bit of a conundrum: As you have discovered, both the bearing and the center bolt are typically irreparably damaged during the process of extraction and should never be reused for that reason. And the only way you can get a new center bolt is to buy a complete new bearing kit. Good luck.

    Welcome to RennTech :welcome: I would suggest going to board sponsor Sunset Porsche's parts website and look up the parts for yourself : http://www.sunsetporscheparts.com/?gclid=Cj0KEQjwh428BRCnvcyI-5nqjY4BEiQAijebwsqIyfF5ZokaEPFkrz-k03mAyqwoUR_lfW3hRRH-g2oaAsc08P8HAQ

    There are no replacement center bolts sold separately, you have to buy the entire kit. Porsche now only sell the IMS as an assembled shaft, costing $1K and requiring engine disassembly to install.

    Just be aware that retrofit HID kits in non projector head lights are illegal in some states due to being non DOT and causing severe glare to on coming driver's (read ticket bait), and will also cause the car to fail its annual safety and emissions inspection. We are forced to fail cars for this regularly.

    OK, a couple of things possible: Have you suffered any shorts or arcing at the battery lately? Reason I ask is that there is a power distribution block on the inside of the firewall on the passenger's side that carries the heavy amperage loads, like the starter. It contains several large bolt in fusible links which are replaceable, and often the source of non start after an arc has occurred. The immobilizer control unit is under the driver's seat, and also has its own fuse in the box itself. You will not be able to see the immobilizer on any scan tool other than a Porsche specific unit like the Durametric, PST II, or PIWIS systems. Of these, the Durametric is the most reasonably priced at around $300.

    Oil pressure is normally tested with a mechanical test gauge:

    While the Autel MD802 is a fine global OBD II tool, it still lacks much of the ability of the Durametric system.
  16. JFP in PA
    There are no "legitimate repair manuals" for this vehicle, Porsche never produced them in print, but only in an electronic form which requires a PIWIS TSI subscription to view online.

    Item #14
  18. JFP in PA
    Welcome to RennTech :welcome: Yes, it could be a DME issue, but a proper scan should pick that up. The codes you have already gotten indicate no signal from the CPS (P0335) and the inability to get a comparison between the cam position sensor on bank #1 and the CPS (P0012), which would seem probable if the CPS were bad, but you have already replaced that. What concerns me is the jumping tack, which is very abnormal. I would get the car scanned with a Porsche specific diagnostic tool for pending codes as the first step.

    I'm sorry, but along with a lot of specific knowledge about this engine, you are going to need specialized tooling, such as the Cayenne camshaft timing tools to do this type of repair: And these tools are both quite expensive, and have only one use, for setting valve, cam or VarioCam timing and also requires a regulated air source between 5.0 and 5.5 bar to complete the repairs. This is well outside what I would suggest is a "do-it-yourself" type repair for someone that has not done it before, or had special training on this engine.
  20. JFP in PA
    Specify what? Loren has given you the probable fault causes for each code, now you need to check each the probable faults to see which one it is.
  21. JFP in PA
    If you hit 16 volts, I would not be surprised to find some electronics damage.
  22. JFP in PA
    Would not be at all surprised as that version is more than 10 years old and predates the cable change................
  23. JFP in PA
    First of all, you have a very out of date version of Durametric; you have 3.0.15.0, the current version is 6.5.2.0. This may be part of the problem. If what this system is seeing is correct, the ABS module is not communicating. This could be a faulty module, or a wiring issue.
  24. JFP in PA
    Either the bearing in the front of the compressor, or the compressor clutch bearing may be seized. In any case, I would suggest taking the car to someone with the necessary equipment to diagnose and repair the system.
  25. JFP in PA
    Check the side ground for contact, the OEM lighter plug in these cars are DIN standard size, a lot of lighter plug in adaptors are not and only make loose contact.
