FRANKFURT—Volkswagen’s luxury sports vehicle unit Porsche AG has launched an internal investigation into the suspected manipulation of petrol engines, German weekly Bild am Sonntag reported.
Porsche has informed Germany’s automotive watchdog KBA, the Stuttgart prosecutor’s office, as well as U.S. authorities of suspected illegal changes to hardware and software that could affect exhaust systems and engine components, the paper said.
“Porsche is regularly and continuously reviewing technical and regulatory aspects of its vehicles,” a Porsche spokesman said. “As part of such internal examinations Porsche has identified issues and has, just like in the past, proactively informed authorities.”
The spokesman said that the issues relate to vehicles developed several years ago, adding that there were no indications that current production was affected. The carmaker is working closely with authorities, he said.
The paper also said that apart from discussions with employees, meeting protocols and hundreds of thousands of emails were being examined in search of evidence, adding KBA has launched an official investigation.
