I turned my 2013 328i xdrive today on today while I was waiting in the car to have the A/C running. the engine wasn't turned on but radios and a/c were running, i suppose this is called radio ready state... so when the car is in this state the engine shaped check control light/emission warning light stayed on.
however, when i turn the engine on and drive, the light goes away? anyone know what is causing this and i am a bit concerned.. it is due for service in 3600 miles, first service.
