It is possible that the dpf filter itself is damaged or restricted to the point that the forced regen/burn is not working to correct this issue.I have seen several fail in the past before needing replaced.If they did not check to see if this needs done and with what is described here this sounds like what may be the cause and it may need removed and manually cleaned or removed and replaced.
