swpender replied to swpender's topic in 92A (Cayenne, Cayenne Diesel, Cayenne S, Cayenne Turbo, Cayenne S Hybrid)Will do and report back. Thank you.
swpender replied to swpender's topic in 92A (Cayenne, Cayenne Diesel, Cayenne S, Cayenne Turbo, Cayenne S Hybrid)Yes. There is a very brief but noticeable drop in power, like a rough idle, just b4 check engine light goes on. Seems to resume normal operation thereafter but light remains.
2011 CTT is 500 miles into replaced cam adjuster fastening screw per recall and getting this and same for Bank 1, which is code P0421: P0431 CODE DEFINITION: • Catalyst 1 Efficiency Below Threshold Bank 2 Any thoughts?
Richard, My problems were resolved by changing out all coils and plugs. I would highly recommend replacing the full line-up. Steve
I changed out all of mine as well. When I dropped my '11 Turbo off at my garage, the service manager said that were going to send a camera into the cylinders after pulling the plugs. My explanation of the fault codes he told me the camera is to check for scoring. He's told 2 other '11 turbo owners in the last month that they need an engine replacement. Porsche isn't helping out either. I was quite happy to hear that my cylinders were unscored.
Loren posted that he would also check the battery and ground wire for corrosion. I hope he is right, but just in case, what did the coil and plug replacement set you back?
My 2011 Turbo has 80k now and the triple fault started a year and 10k miles ago, when it was still under CPO warranty. I guess the dealer service departments are incentivized to do the most expensive fix, so when i took it in, they replaced the coils on misfiring cylinders. Now that the warranty is expired, i sure hope you are right on the battery issue since it's acting up again.
Richard, there is no requirement to take the car to dealer for scheduled maintenance. I'm on my 3rd Cayenne and never use dealer for oil changes. Why do you state that the warranty is for 2 years? Porsche CPO is 100,000 miles or 5 years, whichever comes first. If your warranty is 2 years, i don't think it's issued by Porsche.
I'd check the driveshaft bearings while your at it. Almost like clockwork, My '08 driveshaft bearings went bad at 100,001. My wife's 06 went at 100,076. Started as a grind type sound and turned into whole car shudders. Good news is that aftermarket replacements are readily available and my son has put 45,000 on the 06 and I put 30k on mine before I sold it, both replacements work like a charm.
If the icon is the one i'm thinking of, it means that the 'display traffic messages' is off because 'dynamic rerouting' is enabled.
Definitely swap the coolant pipes to the updated metal ones. While you are at it, the Sept. 2010 TSB provides a 4 year 50k warranty on replacement coils with part numbers 948 602 104 07. 955 602 101 04, and all later part numbers. My '06 and '08 S's each greatly benefited from a switch to Total synthetic motor oil, which generally corrected the 0021 fault code that appears in many posts in this forum. Good luck with your new car. Enjoy.
Cardan shaft replaced. Didnt take long to go from vibration to the sound of live fire. I wasn't prepared to hear that sound from that car. Luckily made it to SpeedSport Tuning in Danbury CT and repaied overnight. The car drives much better, especially in Sport mode, which leads me to think the shaft joint deterioration affects performance over time, but slowly enough that its not so obvious. Boiling a frog analogy. early warning would be nice.
Do you feel it under the armrest? I've just started to feel same on accel under mine. Had a valve issue but didn't swap out o2 sensor and the vibration seems to have started at the America time. At the same time.
Did you feel the shaking in the armrest area or from engine compartment?
