How many of these "New" DPF filters have been reported here that are not quite that new, or properly cleaned? Seems there are more than a few "New" filters out there that are junk. This appears to be a common situation with some of shops. They are replacing these DPF DOC filters with inferior units, not cleaning them properly, or not even changing the filters and just charging the customer. Same can be said with these fuel pumps and ceramic plungers. How many owners were told the plungers were steel, only to take the unit apart and find ceramic? Again, a common "issue".

I would check the DPF filter, or better yet, get rid of the damn mandate.
