Did you have a very rough idle at cold starts?
I took pictures of the engine data before and after starting the car. What data should i upload here?
Hi, i have an Cayenne S 2008 model. My high pressure set point value is 40bar at idle and my high pressure actual value is around 4-5 bar at idle. Is this as it should be? My car takes a long time to start after not being used for about a day and when it starts it gives me a very rough idling. This goes away when i revv a little bit or when i put the car in drive or reverse. It gave me a 1026 error a couple of days ago. I deleted it and it didn't came back.
I also forget to mention that when i put the cayenne in Drive or Reverse it also goes to a stable, normal idle.
But as it doesn't give any fault codes i don't know what the problem could be. Also HPFP values seems ok..
Yes i can, I have a piwis tester at home.
Did you got an Check engine light?
Hi, Since a few weeks I am the owner of a Cayenne S 957 4.8 from 2008. But I notice that the car struggles to start after standing a few hours. When I try to start it in the morning it takes a few seconds to start and then it idles quit rough. It seems to misfire in some cylinders. When I press the accelerator to 2000rpm for a second or 2 it goes to a "normal" idle and the shaking and rough idle are gone. No error codes are shown on the dash or Piwis tester. There is no unusual noise coming from the engine and it had a new battery last week (unfortunatly that didn't fixed the issue).
Hello, I recently bought my first Porsche, a Cayenne S from 2008. When I bought it I thought the engine was running fine, started OK, no bad ticking noise or whatsoever. But maybe I am to obsessive but now I am not 100% sure my engine is making the right sound. So I tried to find videos about a normal good running 4.8 engine but seems like all of them on youtube have some kind of problems. Is there anybody with a good running engine who wants to make a video and put it online? It can also be used then as a reference for other buyers who have no experience in Porsche engines. Kind
Hello, I have also the 1023 error and hard to start problem. How did you resolve it?
