So, wouldn't the OBD-2 compliance be enforced for a '95-to-'97 Diesel? Even though '95 model-year could exempt an imported (or made in the USA for export) vehicle from EPA, DOT and NHTSA regulations under that 25-years rule, I'd be quite skeptical about it also applying for any U.S.-spec vehicle retrofitted with a non-certified Diesel engine.
