I also got the CEL and when they got the codes out it was saying that my lower active shutters were staying closed. Not good They have replaced the lower shutters and now they are working as designed. I waited overnight to make sure the car was cold. Then took a movie of the operation of the shutters. It is interesting to me because I am retired and have no hobbies. So when you shutdown your engine the lower shutters go open unlike the kidney grill shutters which go closed on engine shutdown. On a cold start the lower shutters go about 1/2 way closed then open for a few seconds then they go closed until the car warms up. The kidney grill shutters stay closed upon a cold engine startup. The lower shutters move in an upper direction. .
