Models affected include the latest Audi A1, SEAT Ibiza, SEAT Leon, Skoda Fabia, Skoda Octavia, Skoda Superb, VW Polo, VW Golf, VW Tiguan, VW Passat and numerous others.
While it’s mainly TDI engines that are under scrutiny – the 1.4 TDI, 1.6 TDI and 2.0 TDI – petrol engines are also on the list.
It’s turbo TSI petrol engines that have questionable CO2 and mpg figures: units include the 1.0 TSI, 1.4 TSI and 1.8 TSI.
The 430,000 2016 model year cars affected will now be reassessed by the German Federal Vehicle and Transport Authority (KBA): new CO2 and fuel economy figures will be determined and published “without delay” by Volkswagen.
What about older VW, Audi, SEAT and Skoda models?
“To what extent models of previous years are affected continues to be looked into,” says Volkswagen.
“Based on what is known at present, the Volkswagen Group continues to anticipate that this will be… around 800,000 vehicles.”
Volkswagen has already committed to swallowing any additional costs that may arise through any increases in CO2 figures – in the UK, for example, VED road tax could go up if revised CO2 figures were higher than previously stated.
The promise is that “all taxes arising in direct relation to the CO2 issue are charged straight to the Volkswagen Group and not to the customers”.
