New Year....Same PROBLEMS! (GM Duramax LIMP HOME 4mph - DEF Fluid Quality Poor?)

Let s get 2023 started with another Diesel EMISSIONS problem. This clean 2013 Chevy Duramax truck is derated to 4 MPH because the ECM is not happy with the DEF Quality. Shop already replaced the failing NOx sensors and filled the DEF tank with fresh fluid. They ran the Service REGEN and the Fluid Quality Test which FAILED! Let s fire up the Tech2Win and see why this beast is sick and what it takes to restore the DIESEL POWER :) HAPPY NEW YEAR! Ivan
