Blu Tec Issue

Has anyone had the check engine light come in addition to the add Blu Tec warning? I have a 2011 350 ML and have added DEF several times and never had an issue. This time the warning does not go away like before and the check engine light is on as well. I added 2.5 gallons as before and do not think it would need anymore than this since I added same amount less than 8000 miles ago. Suspect I have some other issue but just wanted to ask if anyone else has a similar issue?
