Volkswagen software also used in Europe

The software at the centre of Volkswagen’s emissions scandal in the US was built into its cars in Europe as well, though it is not yet clear if it helped cheat tests as it did in the US.

A day after long-time chief executive Martin Winterkorn stepped down, a member of Volkswagen’s supervisory board said he expected more resignations at the car manufacturer in the wake of the scandal.

The US Environmental Protection Agency disclosed that stealth software makes Volkswagen’s 2009-2015 model cars powered by 2.0-litre diesel engines run cleaner during emissions tests than in actual driving.
