Glad to know it’s not just my truck then. But that still doesn’t sound like proper operation to me.I also have a 22 and my truck always fills the dpf faster in the summer once the temps warm from the winter. I’ll go all winter with the gauge barely moving off 0. Now that it’s stopped snowing and is warm I go 200 to 300 miles between regens. In the winter it’s only at 24 hours.
