The 2011 Porsche Cayenne Check Engine light could turn on for a variety of reasons. One of the most common reasons is a loose or damaged fuel cap. If You notice the light shortly after You've refueled Your car, this is most likely the culprit. A low or dead battery is another common reason. This issue would of course likely be noticed before any warning light as You will have trouble starting the car or using certain components such as the headlights. Failing parts such as the catalytic converter or the mass airflow sensor will trigger the CEL. Another common issue is vacuum leaks. You may notice a high idle on Your RPM or unintentional surging.
