That car manufacturers pull out all the stops to make their cars more economical and cleaner in tests make it look like than achievable in practice, that’s not news. But Volkswagen has extra mile done by using software to cheat at emission tests in the US

.

That set at least the US Environmental Protection Agency and the California Air Resources Board. They let Volkswagen officially know that it has violated the rules in their eyes, and now do further research to substantiate their allegation.

That automakers seam-sealed with tape and remove normal parts to show in laboratory tests, lower fuel consumption, which is already known. But Volkswagen has the US environmental regulators aware of the patch required to have with software. A number of diesel cars from Volkswagen and Audi has on-board software that can establish whether there is a test, set EPA and CARB. In test situations which software then adjusts the engine settings. These settings are undone when the vehicle normally used. This leads to considerable differences in the emission of nitrogen oxides. Compared to the laboratory tests the emissions, in practice, may be a factor of 40 higher, according to the environmental regulators.

Double the error

This sin Volkswagen two but by the rules that apply to emission testing. It is forbidden to start a car to provide for inspection on board with a provision that aims to sabotage the test. And it is also forbidden to cars to market approval certificates that the cars in question do not comply. It involves the Jetta, the Beetle, the Audi A3 and the Golf which marketed between 2009 and 2015 and the Passat in 2014 and 2015. Volkswagen has admitted according to EPA that the cars are equipped with a facility for the emissions tests to manipulate.

The EPA still broods on the sanctions that will impose the Volkswagen. Meanwhile, Volkswagen obliged to modify the offending vehicles. For owners of the admitted nepcertificaten cars and has no other effect. Volkswagen already. Aandel Holders are very concerned about the consequences, including the extent of the possible penalty. Volkswagen shares this morning yielded nearly a fifth of its value on the Frankfurt stock exchange.
