My Cayenne S 2008 won't start. I turn the ignition key and all I see is the Porsche (red) logo turn on and the mileage counter light turn on. Steering is locked, the head unit works and I can hear audio. Normally I would hear a click and then all the indicator lights would on and I would hear the soft beeps but now I don't hear anything. There is no steering / ignition faulty codes showing up on the dashboard.
Has anyone experienced this? Appreciate the help.
2002 911 C2 Coupe
I'm having the classic misfire on cylinder 1 when the car is wet. I used contact cleaner on the ignition wire plug into the coil and it works fine for now. I/m sure when it gets rained on it will misfire again. Already replaced spark plugs. I discovered there is a tear in the little orange gasket (green arrow in photo) on the ignition wire connector and water is getting in there when it rains. Anybody know where I can find a replacement without buying a new $812 engine wiring harness?
SO, I got a beautiful CEL on my 02 C4S coupe 6 speed with 63k miles on it. After diag, the shop found a misfire coming from 3 cylinders (#4,5,6). The initial recommendation was to change the coils and plugs. So I changed all the coils and plugs on both sides. After completion, the misfire was still occurring with a heavy rough idle, this time, specific to cylinder 6 only. Then, i changed the injector for cylinder 6 (shop recommendation). After the injector, the rough idle was still present with the engine light as well. Then, the shop performed a leakdown test and found gas in cylinder 6. They cleaned it up, swapped coils from 5 and 6 to test proper functionality of coils. The leakdown test did not show any leaks however. SO after this was all said and done, the shop put it in additive, filled up the gas tank, and drove it for 50+ miles or so. The car function properly according to them and I drove it as well, and there no idle, no shaking, no engine lights, nothing. A week after I picked up the car from the shop, the rough idle began again after I gave the engine a little rev. The engine light was flashing, and the rough idle began again. The shop said it could be the lifters for cylinder 6.
Any thoughts or anyone here experience similar issues with this? Any help would be greatly appreciated. I would like to gain some knowledge before taking it in back to them and throwing more money at this with no end solution.

Recently the CEL came on. My OBDII reader showed misfire for all cylinders (this was on a cold start, so not warmed up yet). Previously it had shown misfire in the ready list so I figured this has been intermittent for a while although the car has been driving fine. No issues with power, hesitation, fuel mileage, etc. So, I went ahead and ordered the coils and plugs and changed them today. Every coil looks perfect. No signs of cracking anywhere. The plugs also looked absolutely fine. What I'm figuring (hoping?) at this point is the coils themselves are failing. See the link for pics. The service history I have shows these were changed at 102,000 miles with the 002 part. The coils I installed are 012. Not sure this is going to make any difference but time will tell.
