  1. As with nearly all Cayenne issues I think a good starting point would be checking and ensuring the battery/batteries and charging system are in good health and operating correctly I’ve been experiencing some weird drivability issues as well and the root cause is pointing to a possible/probable electrical system issue
  2. Need to get it to a Porsche dealer or specialist who can pull the DTCs My guess is a failing transfer case/transverse lock module and solenoid
  3. So I did some more data-logging today during a portion of my morning commute. Mostly low speed (below 25MPH) stop and go but a couple of places where I could really go fast (30-35MPH). If I am understanding and reading this data correctly my check engine light codes P2227 & P2225 are being caused by a vacuum and/or boost leak? Take a look and pay attention to time slots 12:59 & 16:57. Something weird happens both times when it feels like the timing is all of a sudden thrown off, and the truck hesitates, stumbles, loses power, and then snap crackle pops through the exhaust like a cheap rice rocket with a fart pipe. And each time this is with a steady easy throttle no mashing. Untitled.mp4
  4. I realized after the fact some of you may not have a .avi player so I reformatted the data-logging file as a .mp4 Untitled5.mp4
  5. So I pulled some live data today and am going through it now. One thing I'm not certain about that caught my attention is the correlation of ambient air pressure drop as intake air pressure rises; I thought this would actually be the inverse of what's being reported? Have a look. Untitled 5.avi
  6. So I tested the battery today and at rest no ignition I'm getting 12.6 volts. With the engine running I'm getting 13.85 volts. Battery is not even a year old yet. Okay no rodents, ECU check sums are checking out okay, BUT - I'm losing boost, and the timing is being retarded in a big way right when the turbos should start to spool hard about 26-2700 RPMs. Spool up to .3-.4 bar and then le poop! Full dump. Power loss, hesitation, stumble, no CEL - repeat. Hmm...curious... I'll try to capture some live data and post it. I'll try cleaning my MAFs too. I ran some Techron through a couple of weeks ago - didn't really need it but it was a gift so...
  7. hmm, both sensors failing at the same time? rut ro... ECU crapping out? rodents in the engine harness... let's have a look
  8. whoopsie! Sorry about that Boss. 2004 Cayenne Turbo, slightly not stock...
  9. Boost leak? Vacuum leak? Clogged cats? Any help or suggestions would be appreciated.
  10. I just recently replaced my hood latch. It involves take the front bumper cover off to get at the latch and microswitch
  11. oof! the dreaded scored bore sound. I had this same knock before having to rebuild my engine. bores were badly scored on the last two cylinders in bank 1
  12. In normal it's mildly stiff body roll is easy to control when pushing it road imperfections are slightly damped In comfort it wallows around and body roll is noticeable when you push it and road imperfections are dampened more than in normal In sport it's very stiff minimal body roll and you feel every imperfection in the road
  13. Update. So new suspension has been on the truck a little more than a month and I’ve driven it hard and a couple of drag strip days. Guess what? The inner tie rods are already shot! No matter because my rack is leaking anyway so I’ll yank the whole assembly at once. My feedback: go OEM on the suspension bits. While aftermarket kits are super attractive because of their costs, they’re not worth it in the long run. After 1 month about 3900 miles and a couple of trips into the RPM Range 2 zone and the inner tie rods are done!?! Not acceptable.
  14. If the ride quality is poor it may have nothing to do with ride height. Check your tires, tire pressures and suspension mounts and bushings for excessive wear.
  15. I had this same problem recently I also recently changed out all my control arms sway links and bushings and adjusted my exhaust hangers while under there and the noise is gone So not sure this is your issue but it may be a place to look
  16. You can certainly have a local Autozone or Pep Boys check your battery or alternator condition for free but best to have a shop with the proper scan tools to check your Cayenne for any active and pending codes. A start stop like that could be any number of faults
  17. Hi Camilee Funny you should ask as I now have a calibration issue with my suspension fault code P1437. My laptop died just as I was coding the last height sensor (HR) so I’m gonna have to do the whole thing over again. But to your question the difference was night and day. The ride much smoother quieter the steering much faster to respond and more accurate. The road feel when really pushing it felt more planted more solid and whereas before I could hear and feel the rear end breaking loose I don’t feel that anymore and no more hop and skittishness under hard braking (my Pig is not stock ?). I changed the full front arms and strut mounts all tie rods and sway bar links and sway bar bushings. On the rear I changed the lower arms upper arms and track arms shock mounts and also changed the rear links and sway bar bushings.
  18. I have replace mine with a used unit. Simple plug and play. That was about 2 years ago. Haven’t had a single issue
  19. Disclaimer Loren I hope that post was okay? If not I’m not trying to promote commercial interest Apologies in advance

  21. No the reset combination of pressing keys “148” simultaneously will reset the unit without a PIN required Even if you do a “factory restore” from the sub menu no PIN is required
  22. I experienced this right before my unit died for good. You can find good used units for not too much but you may wanna consider a rebuild or an aftermarket unit as well.
