  1. It's over 14 volts and steady when running, but I tested it with ignition off using a multimeter a couple of hours after returning from my trip and it measured 12.17 volts. I'll get a new battery tomorrow and report back.
  2. My wife's 2008 Cayenne S has had a very slight and somewhat intermittent vibration at idle for the past few weeks. Last weekend I hooked up my durametric. There were no trouble codes. I didn't see any significant number of misfires. I looked at the set point for the HPFP and the actual value and they were very similar, suggesting the HPFP is fine. I took a 250 mile round trip yesterday-today and today, at the beginning of the return trip the check engine light came on (solid, not flashing). The car runs fine but when I got home I tried revving it and it won't rev above 4K RPM (I'm guessing this is 'limp mode'). So, I pulled out my durametric and checked for faults. There were faults in 3 modules as follows: 1. In the Engine module there were 4 faults: (a) 0131 O2 sensor circuit low voltage bank 1 sensor 1 value below lower limit value (b) 1355 Valve lift control, cylinder 3 Implausible signal (c) 0301 Lost communication with gear shift module Value below lower limit value (d) 44FA 2. In the Air Conditioning Module (a) 819 Air-conditioning pressure sensor Open circuit/short circuit to ground 3. In the Automatic Tailgate module (a) 3234 Function restrict. due to critical vehicle electric. system condition Here is the work log which should be able to be opened with the durametric software Work Log-2016-12-16_04-50-20-PM.htm I clear the faults and short tested, and the only one that remained is #3 (Tailgate module). I've been wondering if my battery is in need of replacement. Would the low voltage to the O2 sensor create a rough idle? And, would that be a problem with the battery or a bad sensor itself? The Valve lift control sounds scary, but it's just an implausible signal so I'm guessing that's also electrical. Loren and other gurus, what do you figure?
  3. Glad they got it figured out and thanks very much for posting this information.
  4. That's the manual release for the fuel filler door lock (for when the power lock isn't working). I haven't looked at mine for a few years but I think it looked just like yours.
  5. Sorry I can't answer your question, but I am interested in hearing more about your engine swap. Did you do it yourself? From where did you get the donor engine?
  6. It's an interesting question. As Loren demonstrated, the 9PA etc. is in Porsche's documentation, but their part numbers often have the 955/957 (and probably 958 too), so this suggests that these numbers are also internal.
  7. Thanks, Loren. Can you please elaborate a bit on looking for air leaks? Are you referring to a leakdown test?
  8. I checked for faults on my 2008 957S to assist EMC2 with a question, and ended up finding some faults about which I wasn't aware. Here's a snip of the Durametric output for the Engine Module: Can someone please tell me what these suggest?
  9. The entire time I've had my Cayenne I get a phantom fault in the electrical system using my Durametric. PIWIS does not show any faults. I informed Durametric of this but they have yet to fix it. I realize that you had a problem and so this fault could be legitimate, but just wanted you to know that this is an issue, at least with my 957S.
  10. Ooops, I missed which subforum you were in (thought it was a 997). I haven't heard of this on a Cayenne but I'm sure others much more knowledgable than myself will chime in. Thinking out loud, I recall reading that some model Cayenne's have two batteries...
  11. If the battery is good, then it sounds like the Battery/Starter/Alternator cable. Search for that to see others' descriptions of the symptoms etc. and see my write-up in the 997 DIY section for the fix.
  12. I recently completed the Battery/Starter/Generator Cable replacement. Attached is a newbie-rated, pic-intensive write-up. Below is the introduction and table of contents so readers can decide if the document will be of use before downloading the pdf. "Recently I changed the infamous Battery/Starter/Generator cable on my 997.1. My car had been a bit sluggish on starting for some time, but, one day when I tried to start it after the engine was at operating temperature it would not start at all, as if the battery were dead. The next morning, after cooling off overnight and without charging the battery, it started. I researched the various Porsche forums and found that the aforementioned cable was the likely culprit. The revised part number for this cable, as of this writing, is 997.607.019.03. So, I ordered the part and undertook the replacement. Special thanks to ‘yvesvidal’ from 6speedonline for his tutorial, as well as a thread by ‘equinox’ on 6speedonline that ‘yvesvidal’ used, and a more brief but, nonetheless useful, post by ‘jkw911’ on rennlist. I followed yvesvidal’s procedure quite closely, though I did change the order of some portions. I’m a detail-oriented person and what I always hope for is that someone has created a highly detailed, picture-intensive write-up of a given procedure (so I won’t have to). Knowing that there are others out there like myself, I put together my notes for this procedure for my future reference and am posting it for those who would find it useful. This write-up is not for everybody as it is newbie-rated, highly detailed and pic intensive. To gauge time-to-completion, I’d guess that I spent 8 hours working on this job. Having now done the procedure, it would be faster, especially with this write-up. A note of caution before embarking on this procedure: as always, there are an infinite number of ways to screw things up so one undertakes this procedure at their own risk. What follows is how I completed the job and, as they say on the forums, your experience may vary."

  15. Update: I just read in another thread that the LN magnetic drain plug has a different torque spec of 19 ftlbs, so will torque to that from now on. Also, in subsequent oil changes I have put in 8 liters to avoid getting the overfull indicator intermittently. With 8 liters the oil level is usually 1 bar down, and sometimes on the full mark.
  16. I can't say if that sounds normal for a CTT, but I definitely hear a difference on the right (passenger) side. Others that know far more than me will undoubtedly chime in, but, depending on what they say, I would take it for a scope to get it checked for the dreaded cylinder scoring on that bank. Hope for your sake that it's nothing.
  17. I used to get that error on my Cayenne until I replaced the bulb (even though the original bulb was still working). Local dealership told me that this can be an indication that the bulb is starting to fail.
  18. I'm not able to answer your specific questions, but I lowered the engine for my coolant and water pump procedure. The write-up is posted here so if you look in the DIY section and read my write-up you'll see in detail how what I did to lower the engine (what brackets were removed etc.)
  19. Thanks, Loren. How is programming the front control module done? With Durametric, or is PIWIS needed, or is it something simpler than that?
  20. I searched under DIY tools, but nothing came up for these codes. I think I'm not searching correctly as I'm sure they're all here somewhere. Any instruction on that is appreciated. In the meantime, my 06 997 C2S is giving me a warning 'check front left side light'. When I read the codes I got the following reading below. When I cleared the codes and short tested all modules, the 8042 front luggage compartment unlocking remained. I didn't drive the car so it's possible/likely that the other ones will come back. I suspect the fog codes are due to the ROTtec drls, and have requested them to send me the resistors that may fix the problem. But what does the luggage compartment one mean? The locking mechanism works fine (as does everything else)? I'm surprised that it would not clear. Any advice is much appreciated as always.
  21. I've been getting the check engine light in my 08 Cayenne S with P8121 "Implausible Signal." I clear it and it comes back in a few days. After just now finding this thread, I'll check the coolant level. I'm just wondering if any of you who posted here, now that some time has passed, have any updates on what the problem was and solutions.
