Thankfully that's not an issue for me as I don't live in California... just passing through....you will not make it in and the VIN will be flagged forever.
To my knowledge......all CTD's have been 50 state compliant since 2007.5 with the introduction of the 6.7L .All new diesels are 50 state compliant. That does include Ca.
.
That's because as Sag2 said it didn't have the California Certification sticker on it. The '07 5.9's were 50 state compliant but we still had to have that cert. I ordered mine from Dave Smith and on the valve cover it has the certification sticker. That's the 1st thing the DMV clerk looked for upon inspection.Salesman at Dave Smith motors told me that all diesel vehicles are 50 state compliant.
I did have a buddy who flew to Nebraska a few years back to buy diesel pickup but California DMV refused to allow it in the state. Not sure about the details, only that he had to sell it out of California.
