  1. Have you fixed the issue at the end? I have exactly the same symptom as you had, going crazy and find no cure! Thanks,
  2. I Have you fixed the rough idling issue at the end? I am having exactly the same issue and very frustrating too.
  3. 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 changed no long ago. Basically it is not derivable when engine reaching hot temperature and would stall, then cannot start. What could be the real issue? I always and only have the CEL P0016 and P0341 for past 5 years and knowing from stretch chain so did not bother to fix it until now. No other CELs and no vacuum leaking. Can anybody help for this weird issue? All the symptoms bringing me to think about bad lubricant and seizing engine, but how? When engine hot aater temp gauge pointing to above middle and stays at 3/5. Any input will be great appreciated! Thanks, Paul
  4. Please keep us posted! MY04 Cayenne-S now 150K miles and only P0016 left. It idles rough and losing power. Good luck!
  5. 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!
  6. 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!
  7. 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,
  8. 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!
  9. 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,
  10. 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?
  11. Yes it is the low voltage issue that caused the PSM failure. Thanksfor the info and helping to confirm the issue; very helpful!
  12. Thanks for the info. I am letting my battery charge overnight and see if were the low voltage issue again!
  13. Hello Guys, Needing your help for the flying pig; problem one coming another, never finished! 2004 Cayenne-S 210K kms. Today suddenly the PSM failures Workshop yellow warning light on while on the road. It were on and off during past years guess mostly because of low voltage. This time with a new and strong battery just changed 2 month ago; alternator with 14V charing; the PSM failures Workshop light stays steady unlike before would got disappeared after off and restart. After some google there is one mentioning about the steering angle sensor; needing you guys opinions. After hooked up the diagnostic tool I could not disable the PSM light and got new errors: Under DME: P0102 mass air flow circuit. Under transmission: 1314 DME control module Getting more challenges; my pig is the lucky one that wining all the rewards! Thanks, Paul
  14. cosmoracing they made the silicone breather hoses for Cayenne-S and turbo in replacing the brittle PVC vent hoses!
  15. Hi Loren, I am about to replace the flex pipes on 04 Cayenne-S that needs to remove the Cat; however, it seems impossible to reach nor even seeing the bolts that connects from the headers. Can you please help with workshop instructions?! Thanks in advanced!
