Good evening and welcome to JustAnswer!!

I see you have a DEF issue and have filled it up but still have the check engine light on... Do you know what codes are setting in the ECM? You will need a scantool to retrieve the codes, and if you don't have a scantool your local Advanced Auto or PEP Boys will read them free of charge... Once I know what codes it has I will be able to tell you how to fix it, but without them we will be guessing as to whatthe issue is...

Talk soon,

Brad
