Without citing its sources, German national Sunday newspaper Bild am Sonntag is reporting that U.S. authorities have discovered non-compliant software in Volkswagen 3.0 liter diesel engines.
According to the newspaper, the software enabled the engines to disable emissions control systems after 22 minutes, beyond the 20 minute period typically used for regulatory testing. The software is said to have been found in Volkswagen turbocharged direct injection (TDI) diesel engines used in the Audi Q7, Porsche Cayenne and VW Touareg.
After admitting that it had manipulated diesel emissions test results for a number of years, Volkswagen committed to a $15.3 billion restitution settlement with U.S. authorities in which it will buy back affected vehicles and fund alternative energy initiatives. However, the terms of that settlement only addressed vehicles equipped with VW’s 2.0 liter diesel engines.
Volkswagen reportedly informed U.S. authorities last year that approximately 85,000 Audi, Porsche and VW vehicles equipped with the 3.0 diesel engines had been rigged with illegal emissions control devices.
A hearing between VW managers and U.S environmental authorities to address the issue is set for August 10.
