The last couple of times I was in a Regen, I was at about 5 grams of soot mass and I shut the car off at that point. I went into a store for no more than 5 minutes tops (probably not even that long) and came back out, started the car, to find the soot grams were at 10. I've never had that happen before, and it's happened the last 2 regens I've had. Anybody else have this happen?
