I have the exact same issue , it seems worse some days . I had the dealership replace the injectors in January , they have no answer. I took it to a local shop and the think it is because of overfilling the tank several times on a long journey several weeks back. They feel that there is a canister that vents the fuel system and it probably has raw diesel in it.They are telling me I should clear up over time and we are monitoring untill the next oil change. And at that time we will dig into it deeper. I will let you know how I make out at the next shop visit.And if you could do the same please let know it is very frustrating. 310K on mine.
Thanks Jeff
