Volkswagen and the diesel model emissions issue
What caused the Volkswagen scandal?
Volkswagen installed emission control software on more than 500,000 of its diesel vehicles in the United States and on approximately 10.5 million vehicles worldwide. This software allowed it to meet EPA (United States Environmental Protection Agency) environmental standards in the test phase, but then pollute during normal driving. According to the EPA and the California Air Resources Board, who were alerted to the issue by researchers in 2014, Volkswagen “defeat devices” detect steering, acceleration and other settings used in the test to switch between two distinct operating modes.
Are models that use AdBlue® affected?
A team of American researchers found that the software installed by Volkswagen even affects the AdBlue® dispenser, allowing it to inject higher doses in the certification phase in order to drastically reduce the quantities of NOx (nitrogen oxides) emitted by the engine. Analysts put the fact that the German company resorted to these measures down to the stiff competition that the company faces in the United States. This case will further complicate matters for AdBlue® Volkswagen who now face the most expensive fine of its kind, amounting to 18 billion dollars. In addition, the brand is still in the process of recalling all the affected vehicles.
