Which of the aforementioned claims regarding the Volkswagen Emissions Scandal is true?

A. The Volkswagen emissions crisis, often known as "Dieselgate," started in September 2015 when the German carmaker Volkswagen Group received a warning that it had violated the Clean Air Act from the US Environmental Protection Agency (EPA).

B. Volkswagen was found to have "intentionally" programmed its turbocharged direct injection (TDI) diesel engines to only activate their emissions controls during laboratory emissions testing in order to meet US standards, even though real-world driving could result in up to 40 times higher NOx emissions.

C. Volkswagen installed this software in around 11 million cars globally, and they allocated nearly 7 billion dollars to cover the expenses of fixing the software that was the source of the pollution claims.

D. According to the German media, high management had been made aware of the deceptive behavior as early as 2007. Heinz-Jakob Neusser, one of Volkswagen's top executives, had disregarded at least one engineer's warnings over the methods, which were reportedly "potentially criminal."

E. All statements are true.
