No, as it usually happens, when you offer advice and ask to be informed when the real problem is found and corrected no feedback was provided.
The last info I received was the owner with the problem had been sent to a dealer in another town with a woman (???) Cummins diesel tech who is reportedly liked and respected.
Who knows? A girl right out of high school with no training would probably be as good as the closest Dodge dealer's service department.
I took my '06 Dodge with FCA symptoms to the local dealer several years ago and their top diesel tech at the time advised me to use fuel additives. TDR members suggested replacement of the FCA which fixed the problem.
