Step 1. Take your Duramax-equipped truck out for an extended straight drive, such as on the highway. The DPF will fill up with soot during typical operation, such as stop-and-go driving. The DPF system will store soot during this type of operation, but the engine will not get hot enough to engage regeneration mode.
You can force a regen with AlfaOBD and that is what he is trying to do. What you cannot do is run the forced regen if there is a fault code present, it will abort. Is the fault code cleared? Need to make sure it is. Also, if you replaced the DPF with a new one you should run the DPF reset function as well to reset the pressure data to start over.

This helps to raise the exhaust temperature, which starts the regeneration process. â‘¡ Using the diagnostic tool: The forced regeneration of the DPF can be
A forced regeneration can be performed by any service shop with the appropriate diagnostic software. The cost for a forced regeneration varies. Generally, it is between $300-$700 depending on the technician’s required diagnostic time and the length of time your DPF regeneration lasts. How can I do a forced regeneration?
It doesn't prompt you that your filter is full, you just need to see the DPF % is maxed out, navigate to the OCR screen and follow the prompts to finish the process. You can have auto regen checked off and it will still auto regen, or you can navigate to the OCR screen and manually do it.
