Investigation revealed a small air leak due to an incorrectly clamped flexible pipe. This was assumed to be the cause of the reoccurrence of the fault (all the Volvo modifications have been incorporated). Discussion revealed that it is believed that the utilisation profile required to avoid this issue somewhat more demanding than that necessary to keep the DPF clear. If that is the case, then it would seem that a final fix is still some way off.
I fully expect to be renewing my acquaintance with the “orange turtle” before the end of the year!
