But it still makes sense that the system would open the louvres and increase airflow to the DPF to assist the process. It had a motorway run recently so I'm not madly anxious about it.

If you stop in the middle of a regeneration it will carry on where it left off at the earliest opportunity , you don't need rpm or speed , just cruising along at 50 mph is ample ...
