My name is ***** ***** I will assist you with your question today.

I'm an independent contractor and I don't get paid until a rating has been made.

We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence!

Do the calibration in the DDDL. There is a spot to calibrate the Delta P. Then try the regen again to see if it fails or not.

If you can, send a pic of the screen that shows the fail. Sometimes that screen can tell a lot where the gauge readings are for the EGR and aftertreatment gauges.
