Daimler probes diesel emissions after US request
German car maker Daimler is investigating what it says are "possible indications of irregularities" in its emissions certification process, following a request by the US government.
Daimler spokesman Han Tjan said the Department of Justice contacted the company last week and it is conducting an internal investigation of its exhaust emissions certification process.
US owners of Daimler's Mercedes-Benz BlueTEC diesels recently filed a class-action lawsuit claiming the cars are programmed in a way that lets them emit illegal levels of emissions, similar to diesels made by fellow German manufacturer Volkswagen.
Volkwagen has admitted that its diesels were designed to defeat US emissions tests.
Daimler says the lawsuit's claims are without merit and that the Justice Department investigation is unrelated.
