If I drive the vehicle there and the CEL light turns off, will they still be able to turn it off? Or will I have to wait until it comes back on? When the CEL light went off, I had it checked at the dealership and they did not detect any problems through the obd port.
I only ask this because this is what happened the first time I tried to take the car back. And its a +2.5 hour drive for me one way.
