VW threw enough money at me for me to sell them back my 3.0L TDI. It had 173,000 miles and vagcom had DPF loading at something over 50%. There is a poster on the Duramax forum that does hauling with his '17 for a living and he's still on the original DPF at 225,000 miles. I asked the question and he didn't mention cleaning in is response.

DPF do the regen then and is all good for stop and go traffic for next cycle.
