In 2015, the German gate maker Volkswagen unveiled a diesel gate incident where 11 million vehicles were equipped with illegal software to clear the emission regulations of the United States. Similar to this case, German automaker Daimler had installed illegal software to reduce the effectiveness of emission control systems on its 42,000 Mercedes-Benz diesel vehicles under its umbrella It became clear.

German autoregulators have announced that Daimler has installed software to evade emissions regulations on Mercedes-Benz diesel vehicles illegally. Regulators have notified Daimler to recover 42,000 diesel vehicles loaded with illegal software.

Daimler has argued that the regulatory authorities pointed out that the software installed on diesel vehicles is not illegal. According to the Wall Street Journal, Daimler will formally challenge the German autoregulatory indications.

The point to Daimler this time is very similar to the 2015 diesel gate incident. In the case of the diesel gate case, Volkswagen in Germany was pointed out by the US Environmental Protection Agency as using fraudulent software to escape emission control, and was fined about 2 trillion yen. Eventually, Volkswagen has been fined not only by the United States but also by the EU, and fines and recalls have led to spending several trillion yen in funds, said Ars Technica of the foreign media.

And the software that is illegal is being installed on vehicles manufactured in the period from 2012 to 2015.

The coolant thermostat used in the diesel vehicles in question is generally mounted on the catalytic converter , and an exhaust gas reduction technology that uses urea to reduce nitrogen oxides to less harmful substances Is not using a selective reduction catalyst.

In 2018, Daimler has been notified by the government's regulatory authorities about the existence of this software, and in June of the same year to carry out a large-scale recall of heavy duty diesel vehicles on another illicit software issue relating to emissions regulations escape.
