Cel, Shutoff Or Reset

On Sunday I had a CEL when starting. I checked the fuel filler cap and it was indeed loose. On Monday I called my local dealer. The service guy said that once sufficient pressure was reestablished the CEL would automatically turn off. Well now it is Wednesday and I have driven 25 miles since the CEL. Will it turn off or do I have to get it reset? This is on an 09 C4S

Give some more drive time - numerous starts and stops are required to verify the problem has been corrected.

Thanks. It is now five days and fifty miles later with 10 or so starts. I still have the solid ECU light. Am I being impatient or is time to get this checked?

Well... maybe read it with Durametric or PIWIS. Both can tell you if it is pending or current.

They can force a reset and see if comes right back.

Hi. Is this problem fixed, I am having same issue with my 2007 C4S, the light is still on after a few drives. Thanks.

Not fixed yet. It has been to the dealer three times now. Each time it operates fine for a few days after they work on it and then the light recurs. The light just recurred last night. Service mangager is scratching his head and in contact with Porsche. Car will go in for the FOURTH time next week.

I disconnected the battery and the computer got reset, after which the message disappeared and never came back.

The car, 09C4S, went into the shop last Wednesday. This time they tell me they ran another "smoke test" and found that the "leak detection pump" was actually the culprit. They replaced it and have been driving it around town to see if the problem recurs. So far it hasn't and they say they will return the car to me tomorrow. I will be happy to have Carlotta back. The Cayenne loaner is fine but not the same - to put it mildly.

If this fix doesn't work I will escalate.

I have had the car back for two weeks now and, cross your fingers, no CEL. They replaced the leak detection pump and carbon canister.
