Authorities from France to South Korea to the United States announced investigations and threatened legal action, prompting Volkswagen to announce that it was setting aside 6.5 billion euros (USD 7.3 billion) in provisions for the third quarter to cover the potential costs of the scandal.
VW shares, which dived 17 per cent on Monday, plunged by another 23 per cent to a low of 101.30 euros during trade on the Frankfurt stock exchange as the automaker's new revelations, including a warning that it will have to lower its profit outlook, sent investors fleeing.
"Anomalies have shown up in around 11 million cars worldwide that are equipped with a specific engine type," the car manufacturer added.
"In order to cover the necessary service and other measures to win back customer confidence, VW plans to set aside 6.5 billion euros in provisions in the third quarter. The group's earnings targets for 2015 will be adjusted accordingly."
The spiralling scandal has led to France calling for a Europe-wide probe into the revelations, South Korea summoning Volkswagen officials, and the US Justice Department reportedly launching a criminal investigation.
The German firm halted all diesel vehicle sales in the United States during the US investigation, which could lead to fines of more than USD 18 billion.
The shockwave immediately hit stock markets, with VW shedding more than a quarter of their value -- or more than 20 billion euros -- since last week.
Other automobile stocks were also dragged lower with Daimler shares down 7.03 per cent and BMW shedding 7.17 per cent today.
