Hi, I had exactly the same problem. The fault was that the engine was not maintaning engine temperature, and therefore would not carryout self regen. The engine temp was fine in the workshop but on the road would not stay above 80 for a significant time. I flushed out the DPF, changed the thermostat and carried out a forced regen. All good and that was 6 months ago. Car had been good since. Stuart
