Is it possible that the battery is the culprit or wishful thinking? I don't know how old the Battery is. Ive owned the car for four years. Its an original Type Porsche battery with no apparent date code. Car shows no signs of battery problems. Any way to tell its age? I will have it tested asap.

 

That looks like an original battery.

 

Battery was manufactured in June, 2017.

 

how can you tell?

 

It is stamped on the negative post.

 

good eye. Thank you.

 

So I deleted the codes, installed a new battery and drove 80 miles. The car passed a NYS inspection with no CEL so far. Before the new battery the CEL was appearing around 60 miles after reset.
