Audi hat doch bereits viel früher angefangen mit dem "SoundDevice", weil sie damals ihren 3 Liter Klapperdiesel nicht ruhig bekommen haben.
Wenn man dem Artikel hier glauben darf, dann ging es bei Audi noch früher los mit dem Beschiss (nicht 2010, nicht 2014 oder 2015):
VW's Emissions-Cheating Defeat Device Was Developed By Audi In 1999 to Reduce Noise

Aus dem Artikel:
Audi originally developed the defeat device software back in 1999, though not for the reason you think. The complaint says that the software was developed for Audi's 3.0-liter V6 diesel as part of an initiative to reduce the characteristically harsh, clattering noise of a diesel engine at idle.
und dann
The Acoustic Function was used on European-market 3.0-liter diesel V6 Audis from 2004-2008, according to the complaint. It was in 2006 when Volkswagen engineers made the fateful decision to adapt the defeat device for its Generation 1 EA189 engine, better known as the 2.0-liter TDI that's now at the heart of VW's scandal.
Und jetzt folgt man einfach den Verantwortlichen und ihren Pöstchen.
