Porsche Cayenne S: I have a 2003 Porsche Cayenne S and the

Customer Question

I have a 2003 Porsche Cayenne S and the check engine light came on the other day. Took it to a local shop that said they can work on it and got the Camshaft Position Sensor/High Bank 1 and they said they took it on a test drive and it died. Then they said that the crankshaft was also showing up as a code. So they replaced that. Well now I go to pick the car up it will start and not start. It also has a PSM light on now. What could be the issue? Battery? Timing Chain?

you say it will start and not start, can you clarify?
Customer: replied 1 year ago.
It starts then you shut it off and there were a couple times it didnt. The brake pedal feels heavy now and if I slam on it it starts. I don't know if when it didn't it was because of the brake pedal.

ok, it sounds like the brake light switch mounted to the pedal, next time it does not start, press on the brake pedal with both feet real hard and see if it starts, also if you have a second person with you, see if the brake lights also come on, that would tell me the switch failed. if the switch is not working it will not allow the cayenne to crank., that seems to me the issue. Please take a second and click the box and rate my service GOOD OR EXCELLENT SERVICE if you feel I have been helpful and please request me in the future.
