Reuters reports that the bulk of the cars – over 1.4 million – have been sold in Europe, although it is not clear if the defeat device software has any impact on official emissions outside the US.

Only 13,000 Audis sold in the US are affected.

The issue affects Euro 5 diesel engines featured across Audi’s model line – these include

  • A1
  • A3
  • A4
  • A5
  • A6
  • TT
  • Q3
  • Q5

The affected Audis are part of 11 million Volkswagen Group cars that feature so-called defeat device software. The ‘dieselgate’ saga has already forced CEO Martin Winterkorn to resign: new CEO Matthias Müller says he’ll “leave no stone unturned” in investigating the issue.
