First problem, don't take the car to the movies! It's door-ding central. The car is punishing you accordingly.

Second, don't feel bad that your CE light came one in under 500 miles. Mine came on during the drive home from the dealership.

The most common reason that I've noticed/experienced with that is O2 sensor or Mass Airflow related. Those are parts that are kinda common to cause minor problems.

If you don't fix it yourself (I hear those are somewhat easy for the DIY types), take it to an independent Porsche specialist. My guess is a $300 fix, hopefully less -not to exceed $500.

Let us know how it goes.
