CEL from oil cap
My 2000 Carrera threw the dreaded CEL last week. I called Momentum Porsche and made an appointment. I patiently waited a little more than 1 hour for the dealer to tell me that I had not properly replaced the oil cap when I added oil. This dealership has done me right several times now. Total price to get CEL fixed, $0.0
 The oil cap was on but not on "properly". Just a heads up on this issue. I would not have suspected that the oil cap can cause the CEL to light up.

Interesting. Perhaps has to do with some kind of pressure.

Bingo! The dealer said there was some sort of pressure measurement that caused the CEL to light up. I am guessing that if I were to have simply replaced the oil cap properly, the light would have gone off after a few drive cycles. But that is just a guess.

The crankcase operates under a slight (~5 inches of water) vacuum to help the low tension piston rings seal, if the cap is loose, there is no vacuum.............
