If your not identifying any soot at the tailpipe your regen system has been working. Your likely running good quality fuel with ultra low sulphur which minimizes the amount of soot that collects in the filter. Before I made the big change mine was going in the 500 mile range while pulling but soot was showing up in the tailpipe. Yours may be in a worst case situation, have a cracked sensor and it will not pick up the differential pressure across the filter to inititate the regen cycle.
