The auto start-stop is deactivated during a regen cycle on the 6.1 Cali. It’s the easiest way to see regen is happening, plus the idle revs are slightly higher.
But in my humble opinion you’re right about turning off stop-start. If we are doing lots of short journeys I turn off the start-stop because the “best” way to get everything coated with diesel wax and soot is to let a warm engine get cold every couple of miles! I had issues with a diesel car and I took notes from my local independent garage and the lead technician mentioned this, along with the other tips around additives, Shell v-power and cleaning additives.
