Go to an auto parts store and have them hook up an OBDII reader to it (I'm assuming the '07's use OBDII?) for free.

Although not as good as the Porsche diagnostic tool, it might be correct.

Hell, I had the dealer misdiagnose my old 996 with the Porsche diagnostic tool. I did a swap-parts-until-fix-method........argh.

Anyways, just throwing out some thing's:

- Mass airflow sensor
- Oxygen sensor
- Cam position sensor
- Coil pack misfires (so many events (misfires) in a given time)
- Manifold air temp sensor
- etc.

Every sensor can trigger a check engine light if enough "events" out of range occur.

If you go to Porsche, they can give you the printout of the data collected in about a 6-8 page printout IIRC.
