I've got a 2005 k12 1.0 , which is not ULEZ compliant on the TfL checker, and has a nox reading on the logbook of 0.1g/km. It has the same engine as the K11 which I think has 0.028 g/km and when I go onto the Emmissons Finder Website the 1.2 of the same year shows 0.044g/km. How is it possible that a smaller engine produces so much more nox and the same engine in a k11 produces 1/4 of the nox . Help please
