Are you saying you are still tuned and trying to get the monitors to set?? The only way this works is to “return to stock” and the. Perform the drive cycles (if you have any questions about those let me know). You can not have anything but the factory tunes on the ECM

You need at least two active regens. Not in the same drive cycle. So basically I drive backroads and stop and go traffic to really load up the dpf. After the second or third active regen I am ready for emissions testing. I use my CTS 2 gauges to let me know when a regen is happening. Driving for 1000 miles in the highways does absolutely nothing for setting these monitors
