In an interesting presentation [video link] at the 32nd Chaos Communication Congress (32C3) held at the end of December, Daniel Lange and Felix Domke gave a detailed look into the Volkswagen emissions scandal-from the technical side. Lange gave an overview of the industry, the testing regime, and the regulatory side in the first half, while Domke presented the results of his reverse-engineering effort on the code in the engine electronic control unit (ECU), as well as tests he ran on his own affected VW car. The presentation and accompanying slides [PDF] provide far more detail than has previously been available. Lange is a former BMW engineer who now runs his own consulting company. Domke is an independent security researcher who became curious about how the code inside his car was gaming the emissions testing.
