Hello there my fellow Cayenne gurus. I started the car (2006 Cayenne S) today and it was clearly evident there was a misfire present as the engine shook quite a bit while idling. In a few seconds the engine smoothed out and ran just fine. There was a check engine light that remained lit solid. I've driven the car several times today and everything was fine except the CEL light remained lit. I used durametric to get a scan of the fault codes and this is what it showed. I erased the coded and the CEL engine did NOT reappear after starting the car. Car runs perfect. Initially I thought I may have a coil pack or plug that is starting the act up but since durametric showed a misfire on ALL 8 cylinders, I'm not sure a coil pack or spark plug is the culprit. There is a VW part number 8SLVASN70000 and controller ID 0159 displayed at the top of the durametric page but not sure what that means. Any thoughts?

Could be battery if it occurred on first start. When's the last time that was changed? Can't help on the codes though. Have the dura metric pro, if you need to borrow it.
