Volkswagen, the biggest motor vehicle manufacturer in Europe and the world, was involved in a major scandal in autumn last year, when it admitted that in 2005-2015 it had equipped 11 million vehicles sold worldwide with software that falsified the results of emissions tests on diesel engines.

In September 2015, the US Environmental Protection Agency (EPA) accused Volkswagen of having installed software that enabled cars to meet pollution standards during testing, but not on the roads.

In the huge emission scandal, Volkswagen promised to pay compensation to diesel car customers in the USA, but the German company is refusing to also offer compensation to customers in the EU.

What steps can the Commission take to prevent such discrimination against European customers, and how can Volkswagen be required to pay compensation to consumers in the European Union also?
