Hello! My DEF fluid light came on along with check engine light. Filled it up with 2.5 gallons of fluid. The lights still haven't turned off after a full tank of diesel and several starts. Thanks!

Welcome to JustAnswer!!!

My name is ***** ***** I'm a 18 yr Dodge-Chrysler-Jeep dealership technician that will be helping you today. NOTE: The deposit you placed will not credit me unless you rate me positive, and feel free to reply to me as many times as needed even after the rating.

Do you know what codes are in the DCU( Dosing Control Unit)?

No, I don't. Is there a way to find those?

Sorry for the delay!!

You will need a scantool to retrieve the codes so we can see what's going on.. Once you have the codes post them here so I can tell you how to fix it..
