It's not what you might think. My `14 CPO i3 Rex seems to be close to perfect and was a great value. Actually purchasing the car and getting it to my house was surprisingly smooth and involved fedexing docs back and forth and happened pretty quickly. My car was put on a truck and arrived 5 days...
quick update. this code went away in its own along with the CEL
Update 2: The CEL light came on again, so I took it into the dealer - I don't think there's really anything wrong, but I want them to run their diagnostic to be sure
