You must maintain a steady or higher speed of 45MPH over a given period of time for the process to complete. In most cases, you'll never know this is going on. Some vehicles state it on the cluster so as to advise you to keep running. If you do short trips or let it sit for long periods without running it either doesn't get the "chance to dance" or the DEF fluid goes bad, not cleaning the DPF...resulting in above condition.

What is the self life of DEF I use bluedef
