Consumer and environmental harm

Discovery of the Dieselgate defeat device

In 2014 an independent research team testing Volkswagen diesel cars discovered a major discrepancy in their emissions data. The levels of nitrous oxide emissions in real-world driving conditions were up to 40 times higher than those recorded in laboratory conditions.

The company finally admitted in 2015 that software had been installed in the vehicles that could artificially reduce emissions under laboratory conditions. This ‘defeat device’ software was installed in around 11 million VW cars worldwide – 8 million of which were in Europe.

Misleading consumers in this way (by claiming their car was less polluting than it was) denied them the opportunity to make an informed choice of another model. Affected cars also saw a rapid decrease in value meaning consumers also lost out on resale value.
