Is it possible the DPF is getting hot enough to burn soot without a formal regen cycle?

This is great point, thanks E85 Sport !

Today (190mi) report:

EGT were in the 370-390C range while climbing a mountain.
400-425C at passing lanes.
440C max observed under steepest continuous section.

I noticed that soot mass value drops after every passing section (where I often need to use left lane )

The non-mountain, flat highway EGT stayed in 280-300C range.

I'll monitor EGTs under other conditions for a couple months, will remember update this thread
