Volkswagen under investigation over illegal software that masks pollution

[Elmura]

I wonder if the same technique is being used on current Euro 6 diesels?
But hey, if measurement of air temp is so critical what happens if driving in Darwin summertime, then later At Thredbo in winter? Can the software map cope with such dramatic changes?
Or, for that matter, New York in winter and Texas in summer

Yes. This is actually quite easy. High temperatures mean less air density which, for the same throttle opening, less fuel is injected. And vice versa
