What year/make/model engine do you have.
You could take your rig to a shop that has the ability to access the ECM via the Insite program. They can download the history of regenerations, it will show when it was done and other parameters. A tech should be able to tell you if the DPF is OK.
If you do this as for a mirror image of the ECM.
