If memory serves, it'll reset after 25 ignition cycles - but it needs at least 3 pressurization cycles in between - that takes approx 12 minutes of engine operation.

Yeah, lived through some cycles once just because I didn't turn the gas cap three clicks (which I hate, I usually hold the button in to set e-brakes even).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Some ***hole stole my gas cap a few days ago. I noticed it only because the "Check Engine" light came on. After I got a new gas cap from Porsche and put it on, the light still won't go off. Do I need to go to Porsche and have them reset it, or disconnect the battery, or what? Thanks...

POST 2Original post

The CEL (check engine light) should turn itself off after something like 20 cycles. Driving cycles. On/off. If you just sit there and turn key on/off 20 times nothing will happen. Disconnceting battery will make you lose all your radio stations and the anti-theft code.... Good Luck.

POST 3 / ORIGINAL POSTEROriginal post

Wow, excellent info. Thanks!

POST 4Original post

If memory serves, it'll reset after 25 ignition cycles - but it needs at least 3 pressurization cycles in between - that takes approx 12 minutes of engine operation. Just drive it for a few days - it should turn off with no problems. J

POST 5Original post

Guess you should lock your car when unattended...

POST 6 / ORIGINAL POSTEROriginal post

Actually I found out that the "pin" that moves in when you lock the car works, but the part it is supposed to pin into is missing. So basically my gas flap does not lock. Argh.

POST 7Original post

I had the same problem only caused by "topping off" the gas tank. These cars do not like that and it will trigger the CEL. Goes away after the defined number of cycles.....just be patient.

POST 9Original post

Yes, that's another issue - if one tops off the tank, fluid (gasoline) can get in the vapor recovery system - and that will trigger an emissions event. J
