Defeat devices/strategies are explicitly banned in USA and European emission standards. What the vw software does is recognise it's on test in a lab and behave impeccably with exhaust aftertreatment working as it should. This involves a different map to that used in the real world, which cannot work in the real world. They're monitoring if the steering is turning, vehicle has been soaked at a set temperature for a minimum period, if all 4 wheels are rotating etc. For the adblue equipped vehicles it appears the dosing strategy is reduced to almost zero due to the size of the tank and not wanting customers to continually be refilling it (USA customers hate doing maintenance or visiting garages except for fuel)
