I got a similar message because I swapped out the stock headers for Agency Power sport header's. If your car is stock and the light comes on again definitely take it to the dealer for warranty repair.

Could be a bad coil. They give weird and inconsistent codes when they fail.

 

Wouldn't a bad coil prevent the car from starting?

 

Probably a bad coil. Take to dealer asap.

 

Well, the diagnosis was apparently an air bubble in the fuel line which caused an error, no coil issue. As it turned out few days earlier, when my car was washed, one of the workers apparently opened the gas door and forgot to latch it. Someone noticed it on Saturday and I corrected it. But when I looked at it I also noticed I didn't have the cap all the way to the last click. The service advisor mentioned it takes a couple drive cycles for the error to occur. However, the service advisor indicated if the warning does happen again, more often than not it is a bad O2 sensor.

 

That'll teach you for letting someone else wash your car.

"Engine Control Fault. Consult a Workshop. Driving Permitted"



Update - the same "engine control fault" popped up again a few weeks ago out of the blue while driving on the Interstate. No subsequent issues driving it on round-trips from D.C. to Richmond and later to Roanoke, as well as an outing with PCA last weekend. I decided to bring it in this week, and sure enough the specific issue is the oxygen sensor. They FedExed the part overnight under warranty so I should have the car back quickly. But just an alert to folks with 718's about this, please advise if you've had the same issue with your models. Also, since mine was built either November or before, it could well be a problem just with earlier models. Doesn't seem to affect driveability but I imagine something happens with the engine controls to compensate.

Need to know what the fault code is to help.

I have the Engine Control Fault message. It happens under full throttle and the engine stumbles badly. It also says it's ok to drive but to consult service dep. My long awaited appointment is Friday. I'll post what they find.

 

Saw the dealer today. Turns out it was because of a weak battery. Never crossed my mind. At least it was easily fixed and not something more serious.

 

Sorry to hear it was so easy, but I guess that's good also!

That's why we always ask the age of the battery... these cars hate old batteries. Even if they "test" fine, replacing them often fixes weird issues. Generally speaking, I recommend battery replacement about every 5 years. On these cars, you can probably go longer, since the battery isn't in a hot engine bay, but it's cheap insurance to prevent scares!

Thanks for reporting back... always good to have closure on issues!

 

My 2018 GTS sat on the lot for a year, I suppose that weakened the battery at a critical time. On the other hand, my 2012 Audi S4 has the original battery and is still going strong. I'm just glad the issue with the Boxster wasn't something more serious.

 

Yeah, it seems these cars are just very sensitive to batteries. That being said, 10 years on the Audi battery is really long... I'd be replacing it proactively, if it was me. (Then again, I'm in CT so cold weather will cause starting issues during the winter, and that's not the time you want to find out your battery is weak!)
