Volkswagen’s emissions cheating program closely follows a set of parameters that are very similar to those defined by the New European Driving Cycle (NEDC), an engineer said this week.

The cheat exists in the ECU’s “main mode,” said Felix Domke, and triggers a normal dosage of urea and other exhaust controls to bring NOx emissions to within acceptable levels.

Domke presented his findings of an unpacked Volkswagen ECU to the 32nd Chaos Communication Congress in Germany.

His findings are mostly in line with what the automaker has already admitted: its 11 million cars worldwide cheated emissions tests by using two different modes for operation, and that its cars could pollute up to 40 times the legal limit of nitrogen oxides when running normally.

But Domke, who said he owns a Volkswagen Sharan equipped with a 2-liter diesel engine, said his own observations showed a severe change in the ECU’s behavior when it exceeded the bounds of what it considered was an emissions test — more than what’s been reported so far.
