But when driving normally, the computer switches to a separate mode-significantly changing the fuel pressure, injection timing, exhaust-gas recirculation, and, in models with AdBlue, the amount of urea fluid sprayed into the exhaust. In the test mode, the cars are fully compliant with all federal emissions levels. According to the EPA and the California Air Resources Board, which were tipped off by researchers in 2014, these so-called “defeat devices” detect steering, throttle, and other inputs used in the test to switch between two distinct operating modes.

We will update with new information as it becomes available. Reuters cited Volkswagen as saying the EA288 engine did not have a "defeat" device to beat emissions testing. This time, they are reportedly interested in the EA288 four-cylinder engine, successor to the EA189 diesel engine around which the Dieselgate investigation has centered. UPDATE 12/4/19: German prosecutors raided Volkswagen's Wolfsburg, Germany, headquarters on December 3, as part of a fresh investigation into diesel VWs.
