Berlin (AP) - VW boss Herbert Diess has rejected a media report on alleged new exhaust gas manipulation of diesel cars as wrong. "Thank God there is nothing in the story," said the CEO on Thursday evening on the ZDF program "Maybrit Illner".
The SWR had reported on Thursday citing internal VW documents, even diesel engines with the modern and stricter emission standard Euro-6 contained a program that recognizes whether the vehicle is currently on a test bench.
Such "cycle recognition" had been used with older VW engines of the type EA 189, that the full exhaust gas cleaning only during the test was running, in contrast, reduced in everyday use on the road or even completely shut down - with a significantly higher output of toxic Nitrogen oxides (NOx). The unveiling of the malicious software operating in this way triggered the "Dieselgate" scandal in September 2015.
On ZDF Diess said: "Test bench recognition per se, you always need, because of course, on the test bench must ensure that ABS does not regulate, for example, that the car behaves properly on the test bench." But the question is whether this test stand recognition will be used to achieve different emissions while driving. "And that's certainly not the case," the manager assured. "The engine has no defeat device." This also pointed to the fact that the engine in question was tested by the Federal Motor Transport Authority and also by external institutes.
The discovery and the admission of fraud programs ("defeat devices") led to the beginning of the exhaust fumes at Volkswagen some four years ago. The then CEO Martin Winterkorn had to go against him and other managers are still under investigation, including the prosecutor Braunschweig. The group plunged into the deepest crisis in its history - the scandal devoured billions in legal costs, the image damage was enormous.
