The South Korean government has launched an investigation into the Volkswagen emissions scandal.
Volkswagen yesterday (Monday) apologised after admitting that it used a device to deceive regulators over emissions emitted during driving.
The South Korean government said it would investigate more than 5,000 vehicles as a result. And it could expand the investigation to all German cars if problems are found.
The German car manufacturers' share price dropped by 20% yesterday after chief executive Martin Winterkorn apologised for the scandal.
The US Environmental Protection Agency discovered that Volkswagen had been using a so-called "defeat device". The device enabled cars to emit fewer emissions during a test than it actually did on the road under normal driving conditions.
