Dieselgate Deja Vu? Mercedes Accused Of Using Software To Cheat Diesel Emissions Tests
Daimler, the parent company of Mercedes-Benz has been accused of using cheating software to pass stringent US emissions test by a German newspaper.
Daimler, the parent company of luxury car marque Mercedes-Benz has been accused of using cheating software to pass stringent US emissions tests by a German newspaper. Citing confidential documents, Bild am Sonntag claims that US investigators have found that cars made by Daimler — a company already under investigation in both the US and its native Germany for excessive diesel emissions — come equipped with software that helps them the stringent emissions testing programme in the United States.
Daimler is one of many carmakers accused of cheating on diesel emissions tests using software trickery since the Volkswagen Dieselgate scandal broke in late 2015. German automotive giant Volkswagen was forced to pay huge fines and issue massive recalls after admitting to secretly installing emissions test cheating software on its cars which emitted up to 40 times the legal limit of Nitrogen Oxides on the go but performed perfectly during testing.
The Bild am Sonntag also states that Daimler's own employees doubted that the company's cars could pass strict US emission norms for diesel vehicles even before the Volkswagen Dieselgate debacle made its way onto the headlines of every major news agency. The newspaper also claims that Daimler employees also questioned whether the functions of the software were even legal to use.
The software used featured multiple functions including one called 'Slipguard' that helped the emissions cleaning systems recognize when the car was being tested in a lab for emissions. Another function of the software called 'Bit 15' switched off the car's emissions cleaning system after 26 kilometres of driving.
Bild am Sonntag claims that the software used by Daimler regulates the application of AdBlue diesel exhaust fluid which helps cut down the nitrous oxides (NOx) emission from diesel engines. The use of the software to regulate the use of the AdBlue, the German newspaper claims, means that many Mercedes cars emitted up to 10 times higher than the legally permitted levels of NOx emissions.
However, Daimler denies any wrongdoing on its part and has stated that it has been cooperating with American authorities over the issue. A spokesperson from Daimler told Reuters, "The authorities know the documents and no complaint has been filed. The documents available to Bild have obviously selectively been released in order to harm Daimler and its 290,000 employees."
