From an engineer's perspective, it will be interesting if cleaning the soot filter on an EGR system is deemed as a maintenance function (in the same way air filters are cleaned) or if it is seen as a customer practice.
I cannot see customers wishing to see their operators handling hot and heavy filters in and out of a machine that burns the soot away - this will be an additional engineer function.
As regards the sales people, do they know the difference yet?
