Prosecutors in the southwest city of Stuttgart have opened investigations against two managers at Bosch’s US subsidiary for aiding and abetting fraud. The news comes as the German car-parts maker, which has its headquarters near Stuttgart, denied involvement in carmaker-sponsored tests on the effects of traffic fumes on animals and humans.
Two diesel-engine vehicles, the Chrysler Grand Cherokee 3.0 L and the Chrysler Dodge Ram 1500, which have been on sale in the United States since 2014, had shown signs of a “reduced effectiveness” of emissions control systems. Bosch software was believed to have been used to detect whenever the vehicle was not on an emissions test bench.
In VW’s Dieselgate scandal, the world’s largest car-parts maker has categorically denied any wrongdoing, insisting that Bosch simply made the components according to Volkswagen’s specifications and that it was not responsible for how they were used.
The two Chrysler models now under scrutiny were already subject to a so-called Notice of Violation by the US Environmental Protection Agency, or EPA. These warnings usually offer the recipient an opportunity to comply with EPA regulations. In January of last year, the EPA accused Fiat Chrysler Automobiles of using cheating software to allow excessive diesel emissions to go undetected, leaving FCA facing a maximum fine of about $4.6 billion (€3.7 billion).
