Daimler could use software to deceive the passage of tests for the content of harmful substances in the exhaust gases in the US

Auto concern Daimler has been suspected of fraud for some time while passing tests on the content of harmful substances in automobile engine emissions in the US. In 2016, some buyers even filed lawsuits against the company, accusing it of using special software to successfully pass the tests, as was the case with Volkswagen.

Now, the US authorities conducting an investigation into the Mercedes, really found that the company’s vehicles use illegal software, designed to pass strict tests for the content of harmful substances in emissions. Judging by the available information, Daimler employees doubted that the cars of the company would be able to pass tests for compliance with US standards even before the diesel scandal broke out with Volkswagen. Apparently, internal tests have demonstrated that the level of nitrogen oxide emissions for some models of cars is 10 times higher than the permissible limits in the US.

Because Daimler was developed software designed to deceive the US regulatory authorities. One of the functions of this software called Bit 15 was designed to shut off the exhaust gas purification 16 miles after the commencement of the trip. Another function called Slipguard took into account speed and acceleration data to determine if the vehicle was being tested. The journalists at Bild am Sonntag were able to find emails from Daimler engineers who were interested in whether these functions were legal.

According to Der Spiegel, next week the German authorities intend to initiate the recall of Mercedes-Benz Vito minibuses. Regulators suspect that these minibuses (and other Daimler vehicles) are equipped with an illegal device that can monitor the amount of AdBlue fluid used by the engines. It is a liquid reagent used for purification of exhaust gases of diesel engines by the method of selective catalytic neutralization.

In addition, both publications contain information that automotive auto titans, such as Volkswagen, BMW and Daimler, funded a study that tested the effect of nitrogen dioxide gas on humans and monkeys.

Unlike Volkswagen, which in 2015 recognized the fact of using illegal software for passing tests for the content of harmful substances in exhaust gases, Daimler insists on its innocence. The company claims that it is ready to defend its good name by all legal means, and published documents were submitted selectively to harm Daimler and its employees.
