I had read something about how diesel engines can use Urea to trap emissions, but it must be refilled frequently, so possibly other manufacturers are using that method. This is tested and proved to work well. However, VW was using another type of method to diminish emissions that has not been well proven. Source: a comment I read on Reddit, so take it with a grain of salt.
Edit: found at least one source on how this works: http://www.greencarreports.com/news/1042727_adding-urea-to-clean-diesel-cars-can-i-just-pee-in-the-tank http://www.greencarreports.com/news/1042727_adding-urea-to-c...

- mrich 11y agoAdBlue is also used in the latest Audi ultra TDI engines. It is supposed to be refilled during normal service (every 30000 km), unfortunately it does not last that long and you have to schedule an appointment much earlier. Refilling it yourself is apparently not possible since a software reset is necessary as well.
