  1. 2011 Cayenne Turbo, 85K miles, 3/4 tank fuel Car started normally 4 times/ran flawlessly for about 45 minutes driving during a 2 hour period. After the last 30 minute rest, the car would crank but not start, then intermittently start after a long crank and subsequently stall. An engine reduced power warning would display and continuous check engine light. Eventually engine would not start or not run for longer than a few seconds. I read/reset codes with the following results: P0192 Fuel Rail Pressure Sensor Circuit Low Input reset and did not return P1031 Fuel high pressure sensor stuck at start unable to reset P1024 Fuel high pressure too high after engine off reset and did not return Car still unable to start/maintain idle. After about 1 hour, I returned to the car, reset codes (this time all cleared)--the car started and ran flawlessly! Anybody else have something like this happen? Should I replace the High Pressure Sensor or order and keep one around--are these prone to failure? I'm having a hard time finding a diagram with the HP Sensor for the Turbo engines, is it located under the intake manifold like the non-turbos? If so, is intake manifold removal on the turbo very difficult? Any other things I should be considering?
  2. MY2011 CTT, 83K miles, intermittently rough idle with the following codes: P1372 Valve lift control, bank 1 P1361 Valve lift control, cylinder 2 P1363 Valve lift control, cylinder 3 P1362 Valve lift control, cylinder 4 I suspect the valve lift solenoid. It looks like an easy enough job (which means I have obviously missed something). Quickster2, did you do this yourself? If so, any tips or tricks to pass on? Additional info (or does anybody else see a different diagnosis or suggest other data to pull?): I have no frame of reference for the camshaft deviation numbers, do these differences from between bank 1 and 2 seem odd, normal, or appropriate for this problem? N010_Nominal intake camshaft angle 130.88 degree CRK N020_Actual intake camshaft angle, bank 1 130.88 degree CRK N040_Actual intake camshaft angle, bank 2 130.88 degree CRK N030_Camshaft deviation, bank 1 3.75 degree CRK N050_Camshaft deviation, bank 2 -0.38 degree CRK N080_Camshaft adjustment valve activation, bank 1 8.99 % N090_Camshaft adjustment valve activation, bank 2 8.99 % M005_Engine roughness reference value 65498 us M010_Engine roughness cylinder 1 1024001856 us M020_Engine roughness cylinder 2 1024001856 us M030_Engine roughness cylinder 3 1024001856 us M040_Engine roughness cylinder 4 1024001856 us M050_Engine roughness cylinder 5 9.27 us M060_Engine roughness cylinder 6 19.28 us M070_Engine roughness cylinder 7 14.75 us M080_Engine roughness cylinder 8 14.27 us
  3. I was hoping to avoid pulling the door panels off--thought I read somewhere that it might be tricky with the powered window shades? Av8sky, did you replace the actuators yourself and do you have the powered shades? BTW, when mine does this, the scan tool typically reports: 000843 Central locking unit, implausible signal
  4. I have had the same issue randomly occurring with my 2011 Turbo. Another related issue was the other rear door would not lock and my alarm confirmation tone would not chirp. It seems to be more frequent in cold weather, so I suspect it may be a lubrication issue. Not sure if it was luck or not, but I tried spraying WD40 Dry Lube PTFE into every nook and cranny I could find near a handle or lock, then put a charger on the battery and actuated the locks and door handles multiple (many, many) times. Both issues have improved, but they're not 100%, so if anybody has a suggestion for an easily accessible spot on these locks to shoot some lubricant into, please chime in. Also taking suggestions on what lube!
  5. **Bonus repair** After accomplishing "Vehicle Handover", 2 longstanding issues with my PCM were cured also! 1. When playing music via Bluetooth there would be a dropout on a semi regular interval. and 2. When manually advancing a music track on the USB input, the display would not immediately cycle to the next song--sometimes not until the next song automatically sequenced would the display catch up to the actual song playing. All in all, this turned one problem into three repairs. My recommendation for ANY PCM problem is accomplish the Vehicle Handover.
  6. My 2011 CTT with PCM v2.4.7 had the same issue recently. I messed with it for a couple days, charged battery, checked fuzes, checked/cleared scan codes, removed phone data, removed phones, tried Factory Reset, tried some percussive maintenance, then finally tried the only thing that worked--Vehicle Handover. One day later, up pops your post! I can confirm this works. It is a minor pain to reinput all your settings, but sure beats the continual 2 minute reboot merry go round. Thanks Mattski
  7. From the subject title, I thought that your car was randomly starting itself-haha! I would check the condition of the battery as well. I have the exact same vehicle and have found that the world turns wonky when the battery is in anything other than excellent condition.
  8. Not sure, I don't have that engine, but it shouldn't be too hard to track coolant hoses around yours?
  9. Did you get anywhere with this? Maybe these electrical diagrams will help. Cay--LevelControlCircuit.pdf Cay-PowerDistribution.pdf
  10. My 2011 Turbo had an intermittent brake light. Dealer troubleshot it to be an overheating LED(s). Had to replace the entire light assembly! $750 if I remember right--OUCH!
  11. Found some wiring diagrams relating to the 12V outlets (AKA Cigar Lighter!) CigarLighterPages.pdf
  12. Haha JFP--as I was writing my response, I couldn't help but think "wow, somebody actually likes that start/stop feature!"
  13. Have you eliminated these possibilities from the manual? I know all sorts of things got funky on mine when it had a weak battery. Page: 153 The Auto Start Stop function is available with limited functionality in the following situations, for example: – If the air conditioning or passenger compartment heating is operated at a high setting or if the defrost function is run for long time periods. – If the battery charging condition is low. – On upward or downward slopes. – During internal vehicle test procedures, e.g. automatic engine checks.
  14. Almost definitely a clogged AC evaporator drain--I've had this occur on my 2011 Turbo as well. Loosen the spring clamp holding the rubber drain boot onto the evaporator and be ready for some water as you disconnect the boot from the evaporator. Once the evaporator drains, blow compressed air into the boot and through the firewall--this should free your clog. While you're down there, you might want to change out your cabin air filter--actually, anytime I replace my cabin air filter, I now blow compressed air through the drain as a preventative measure.
