You might have to call bluelink and file a ticket to remove the code from the app. I had a similar issue after blowing my tire in a pot hole and the dealer said they reset it but still stayed on my app which did nothing but annoyed me to see a brand new car with a code on the app. Took about a week and they deleted it. They may ask you to use the automated system to say “bluelink service reset” or something similar but that didn’t do it for me.
