That's something I cannot comment on. My role is to conduct the required testing to find out whether there are cases, with vehicles and engines, of non-compliance.
My team administers six vehicle and engine emission regulations that look after the emissions of pretty much all on-road vehicles and off-road vehicles that are operated on the road. We select test specimens every year, based on our risk analysis. We conduct the testing, and if there's evidence that these vehicles are non-compliant, we turn them over to enforcement, who work with the prosecution and can talk more about the way the follow-up work happens.
