EPA caught VW cheating - how does the car know it's being tested?

Apparently Volkswagen/Audi cheated on the USA emissions tests since 2009 to 2015 by turning off the EGR to lower nitrogen oxide emissions ONLY when the car was being tested for emissions.

Note that this applies to DIESEL cars only, apparently. Jon |
