idling won't provide enough heat for the particle filter to burn off.
Besides it does that in cycles anyway.. It stores particles till it gets hot enough, then does a burnoff cycle..
My BMW has one , and a start/stop function for red lights.
I would imagine BMW would not put in the start/stop function if it would cause the burnoff cycle to work less well..
The particle filter does cause problems for people that only drive short distances and the engine never get's hot enough...That kind of use will clog the particle filter over time.
