The German sites of carmaker Opel, a division of PSA Group, in Ruesselsheim and Kaiserslautern were searched by prosecutors as part of a probe into diesel exhaust emissions. The authorities are checking 95,000 vehicles equipped with Euro 6 diesel engines to see if they used software to manipulate emissions, according to the Frankfurt prosecutor’s office cited by Reuters.
The engines are used in Insignia, Zafira and Cascada models. The carmaker confirms the investigation saying that is a preliminary proceeding for the case.
“We cannot comment on details concerning the ongoing investigation at this moment in time. The company is fully cooperating with the authorities. Opel reaffirms that its vehicles comply with the applicable regulations,” said the carmaker in a press release.
The Opel Zafira and Cascada were developed when Opel and Vauxhall were still owned by General Motors. The American group sold Opel to PSA Group in 2017. Opel admitted in 2016 that Zafira model has engine software which switched off exhaust emissions treatment system under certain circumstances. The carmaker insisted at the time that it was making use of a legal loophole.
