FRANKFURT — Prosecutors in Stuttgart, Germany are set to fine Mercedes-Benz parent Daimler between 800 million euros ($895 million) and 1 billion euros ($1.12 billion) for diesel-related violations, German magazine Der Spiegel said in its online edition on Friday.
A fine of up to 5,000 euros per vehicle is being considered by the Stuttgart prosecutor, the magazine said, so that could potentially be far more than 1 billion euros in all.
A spokesman for the prosecutor's office said the investigation was ongoing and would not be concluded before year-end.
Daimler declined to comment while the investigation was under way.
In May 2017, German prosecutors searched Daimler offices as part of a fraud inquiry related to possible manipulation of exhaust gas after-treatment in diesel cars.
Daimler also faces regulatory scrutiny by United States authorities. In February 2016 the U.S. Environmental Protection Agency asked Mercedes-Benz to explain emissions levels in some of its diesel cars.
In May, Stuttgart prosecutors fined Porsche 535 million euros and supplier Bosch 90 million euros, while prosecutors in Braunschweig fined VW 1 billion euros and Munich prosecutors imposed an 800 million euros fine against Audi.
