Wolfsburg - Volkswagen may have to set aside more than the $7.4 billion it has so far allocated to cover the costs of an emissions scandal if car sales suffer, its chief executive said on Wednesday (Oct 21).
Matthias Mueller told reporters after a tour of VW's headquarters in the German town of Wolfsburg: "The 6.5 billion (euros) applies to the recall.
"I can only speculate about any further provisions. Should there be a change in sales volumes, we would react rapidly."
Lower Saxony Premier Stefan Weil, a VW supervisory board member, said sales had been stable in October so far.
Volkswagen also confirmed it had stopped the sale within the European Union of new cars containing the software that can cheat diesel emissions tests.
VW admitted on September 18 it used illegal software to manipulate emissions tests on diesel vehicles in the United States, sparking the biggest business crisis in its history.
The admission has wiped about a quarter off its stock market value, forced out its long-time chief executive and sparked investigations and lawsuits across the world.
Volkswagen has suspended Frank Tuch, head of group quality control, two people familiar with the matter told Reuters.
Tuch is the fifth suspended worker whose name has become public. Volkswagen declined to comment and Tuch did not reply to repeated attempts by Reuters to contact him.
Asked whether a small group of employees could have alone been responsible for the deception, Mueller said: "We are still deep in the middle of the clarification, including the question of the possible culprits and causes."
Mueller, who replaced former chief executive Martin Winterkorn a week after the scandal broke, said the investigations were "relatively extensive and complicated" and went back to 2005.
