My thought also. Will look at it this weekend and report back.

They are connected to wiring harness. The wiring is so tight that there is no way to cross wires from one cylinder to another, at least not on my Cayenne.They are all the way into the spark plug hole, so as best that I can tell, they are connecting to the plug. They are tight and the cover screw is tightened on the coil to the engine. Sent from my LM-Q730 using Tapatalk

Hi all, I've not posted much but I am at my wits ends. I have a 2003 Cayenne Turbo that has been running great with loving maintenance. Recently, I had a new coolant leak that I knew wasn't the pipes or the coolant tees as I had replaced them. I removed the intake plenum, found the leak was the small plastic "h" hose going to the rear of the engine under the plenum and replaced it. Everything put back together. Then, I started getting random misfires P0300 errors with P0301, p0302, P303 and P0307. I replaced coil packs with aftermarket coils, no improvement. Thinking I got bad packs, I bought the Beru packs. Error P0300, P0302 and P0307 remained. Replaced spark plugs on cylinders 2 and 7. No go. I still have random misfires on those two cylinders and I am feeling beaten. Today, I thought I would try some injector cleaner, Chevron Techron, to see if it cleared anything up. Maybe an intake got dirty when I had the plenum off. By the way, I replaced vacuum hoses also. No coolant leaks, and no vacuum leaks throwing codes. No P0200 codes either which would indicate injection issues. Each pack and spark plug made improvements, until now. No Durametric codes now except the P0300, P0302 and P0307. Rough at idle and can feel small misfires (is there such a thing as a small misfire)? I was getting this in shape to trade in come March. Now, I am despondent and don't know what to do next except possibly take it to Porsche and spend more than I will get back. Do I just need to try the injector cleaner and drive it a little more? Afraid to drive it too much. Any good advice will be welcomed.

Hi ya'll, I have a 2003 Cayenne Turbo and for the past six months I have had to run the throttle adjustment adaption frequently. It could be related to the vehicle sitting for three or four days, but I have most noticed this usually after wet or very cold weather. Do I need to replace the accelerator pedal with the sensor or is something else causing the settings to fail? After I run the adaptation, everything works fine for days or even a few weeks. It just seems as if the settings are lost like would happen if you replaced the battery or MAF. I don't know if I have a battery that is going weak when the vehicle sits for several day, or if it is related to the wet or the cold, but this seems odd that the settings seem to disappear after some time. In using my durametric cables, the only code I get consistently is P1541. Thanks for any insight.

Yes - if you haven't fixed this yet, I had the same problem. The hole in my oil pan came from the repair shop - of all places - putting in a bolt that was too long on the bottom engine cover. It rubbed a hole in the pan! I repaired this doing the following: 1. Dried the oil around the hole. 2. Using High Heat sealant, I made a small ball and stuffed it in the hole. 3. I used high heat JB Weld over the sealant and let it all dry. 3 years later and still holding. No leaks, but I don't go back to the same repair shop, which is supposedly Porsche certified.

Here is page 139 from my manual attached. I leave my setting off.
