RAM 1500 Diesel General Discussion
My DEF Gauge is still reading 1/2-full even after filling with 4-gal of DEF from a Pump at Flyin' J. My 2014 EcoD threw a P203E code, which I cleared with a scanner. I can't tell if the system is using DEF or not, but the CEL hasn't returned.
Do I risk any damage to the motor waiting to see...
