It appears that this car is not for sale, but in the personal collection of a dealer. This thing is so cool! Headlight washers, EA81t, cool wheels, and the floor mats are epic!

the codes will clear on their own once the issue is resolved. it is real-time information. it only shows the code if an issue is detected. solve the code and the light goes away, maybe after a drive cycle or two.
thanks for getting the info out on the scanner, that's awesome, got one in my amazon cart.
i think most of us are rookie-ish when it comes to circuit board diagnosis and testing.
