My 2016 CC F350 DRW showed a message Saturday that speed would be limited to 50MPH in 50miles. I acknowledged the message and received an Exhaust Fluid System Fault. Went to Autozone and no DTC codes are showing. The DEF level shows as OK when I do a system check. I’m still under the power train warranty sobI don’t want to do a ******. Does anyone have any suggestions. I have an appointment at the dealer on Thursday.
