Thanks for the technical explanation. For a regulatory system however I would assume it’s important that a third-party that follows a standardized procedure can reproduce low emissions, otherwise who could verify that numbers were not forged? If I bring my car to the testing to the accredited testing company in Germany, they test the exhaust fume profile and give me a certificate if it’s within range. I cannot just run my own testing regime and self-issue that.
