Redlined

[mav1178]

If you have no issues with the car in the near future, just count your lucky stars and move on.

If you have oil burning issues or loss of power, you need to have a compression/leakdown test done to make sure no valves floated to hit the pistons.

Dont know if it can be cleared.

Are they referring to the freeze frame data stored when you get a DTC?

I could see how unplugging the battery would clear those codes, but with Porsche, the ECU stores all ignition events (ever) and has a category that counts and time stamps those over the defined redline.

Does anyone know of a way to check your ECU for overrev history?

He isn't going to answer. He was banned 4 years ago.
It is aid that these ECUs do not store long term data. Makes sense they wouldn't at the price point of the car
