DPF regeneration status. 0 if not burning. 1-255 if burning (percentage completed). DPF fill percentage (0-100). Distance since last burnout (in kms). In case of Opel Insignia these are following PIDs - (223274, 223275, 223277). Finding PID codes for your car might be challenging. Personally I couldn’t find anything online.
