  1. Yes both fuel pumps have changed! The vehicle start in cold no problem and no hesitation, only when in warm up then the RPM drops much like low to 440 and then stalls eventually.
  2. Hello, I have read that you guys have concluded to be engine mounts issue. My MY04 Cayenne-S case is different since the vehicle engine after warm up the RPM it drops very low and die eventually, then would have very hard restarting; something like fuel choked of being too rich. However, when the engine is cold then no problem to start right away and no shaking! I have changed everything can think about like fuel pumps, fuel regulator, fuel filter, mass flow meters, ignition coils, spark plugs, breather hoses, throttle body..still no solution : ( Any other i
  3. Hello, Have you found the issue for the drop rpm issue? I have changed everything can think about but still with low rpm stall. Thanks,
  4. Have you fixed the engine stalling issue? I have MY04 Cayenne-S and having exactly the same issue. Find no answer at all but seems many people having with the same issue.
  5. Hello everyone, Getting hopeless for this flying pig again. I have the same issue when the MY04 Cayenne-S after warm up and got RPM very low and then stall. The pig is currently 145K miles. I have only 2 CELs currently P0016 and P0344 but being long time already for past 5-6 years (believe bank 1 camshaft chain starched and too big job to fix), until recently warm up stall issue and the car can't be derivable anymore when being in closed loop after warming up; keep stalling and then could not start anymore. need to wait until cool down. Cold start no probl
  6. Have you fixed the issue at the end? I have exactly the same symptom as you had, going crazy and find no cure! Thanks,
  7. I Have you fixed the rough idling issue at the end? I am having exactly the same issue and very frustrating too.
  8. Hi, I have MY2004 Cayenne-S and getting hopeless. The car can start no problem each time when is cold and very strong cranking, but when the engine gets hot it can't be cranked...seems like seized engine. Changed 3 new batteries, 3 different good brand names batteries but no help, so believe it is not battery issue. When I forced to crank when engine hot couple times I can smell electric short...guess is too heavy to crank and killing the starter. Also the engine is running poorly when engine hot and forced the RPM to be very low and then stall. Used Mobil1 0W-40 engine oil and change
  9. Please keep us posted! MY04 Cayenne-S now 150K miles and only P0016 left. It idles rough and losing power. Good luck!
  10. I have done my MY04 Cayenne-S replaced both sides with the aftermarket flex pipes ordered on Ebay. It is kind of impossible to DIY unless replacing with complete OEM part, since it requires professional welding that need twisting angle welding to flex pipes. I sent to a bodyshop friend in Montreal and charged me 7 hours labor. Very poor design in exhaust system including to change O2 sensors. If you got chance to do the flex pipes job remember to change O2 sensors at the same time. Hope it helps; good luck!
  11. Thanks for the sharing and info. I really went into this P0016 for a while and tried alot to fix it. I believe I am in the worse scenario is with the bank1 timing chain stretched. I have actually changed the bank1 actuator solenoid and camshaft sensor but no help. Any info to adjust the timing or change the chain without pulling engine? Thanks!
  12. Hi Yes after delete the P0016 usually it returns in about 20km. I read the service bulleting about retiming timing without pulling engine but the info is vague. Guess even timing expert is needing to pull engine so It should. The pig is running soft and with much consumption. Any info will be appreciated! thanks,
  13. Hello, Sorry for the late reply; missed the message. Unfortunately I have not fix my issue yet due to the complication of pulling the engine. It is my only CEL stays on all the time. For me this car is becoming obsolate and not worth to spend too much on it! Good luck!
  14. Hello, I have MY04 Cayenne-S with 210K and having the P0016 for a while already; hating to see the CEL on. Wondering how difficult and what procedures involved for re-timing? What's the cost for the job? I am in Montreal, QC. Thanks,
  15. LOL..indeed! I am in Montreal, Quebec it is now -13C **** winter. Could not believe I just paid $300 for a brand new AGM battery! After full charged the battery it is fine now whole day of driving..should I claim for warranty the battery?
