My car was in a shop for a while for some work and when i got in it I saw a message. It was dated during the service. It is an emission message. When I go to look at the message screen, all of the tabs are greyed-out besides the all message one and one other. They continue to show the emission warning. There is nothing wrong with the car anymore but it won't let me delete the message. any ideas how to delete it? or clear the message?
