What makes the Check Engine light come on on a Porsche?
Code: P0344 Gas Cap: A loose, damaged, or missing gas cap can trigger the check engine light on a Porsche. A loose gas cap can allow fuel vapors to escape, which in turn decreases fuel economy. Plus, it is also increasing harmful emissions, which is why the check engine light comes on.
Why is my Check Engine light not working on my Cayenne?
Secondary Air Pump: Older cayennes have secondary air pumps, which inject fresh air into the exhaust manifolds to lower emissions. However, this system can cause several problems. With time, air hoses can become very brittle and break under vibration. Another common failure point is the pump itself, as fan rotors brake-off.
