VW cheating probe spreads to CO2 tests

Source: | Date: Nov. 4

  • Volkswagen has admitted it had found problems involving carbon dioxide emissions on 800,000 cars - including some with petrol engines - at a possible cost to the company of about two billion euros.

  • The problems are a different issue from the scandal Volkswagen has been facing since Sept. over the excess nitrogen oxide emissions from up to 11 million vehicles worldwide fitted with software designed to cheat at emissions tests. Carbon dioxide emissions depend on fuel consumption, not its emissions-control systems.

  • However, the company said it had discovered the issue during comprehensive investigations it had promised following the emergence of the NOx cheating scandal.

  • The statement gave no information about where the affected vehicles were sold, the brands affected or whether they involved diesel or petrol engines.

  • "During the course of internal investigations, unexplained inconsistencies were found when determining Type Approval CO2 levels," a company statement said. "Based on present knowledge around 800,000 vehicles from the Volkswagen Group are affected."

  • However, the company told the Financial Times that the vehicles affected were "mostly diesels," although for the first time petrol engines were involved in the scandal. The vehicles' emissions were understated and fuel economy overstated.

  • The vehicles all have 1.4 litre engines - they are mostly VW Polos and Golfs but also some Audi, Seat and Skoda cars.
