Data released in December revealed that numerous Audi and Seat petrol and diesel models have had their official CO2 figures revised upwards since the parent VW Group issued a statement claiming that investigations had “largely concluded”.
The statement, made on 9 December, identified nine VW branded vehicles as having figures that would need to be re-evaluated. At the same time the original estimate of 800,000 VW Group cars being affected by wrong CO2 figures was downgraded to just 36,000.
After identifying that “during internal remeasurements slight deviations were found on just nine model variants of the Volkswagen brand” the statement concluded that “the Group's subsidiaries Audi, Skoda and Seat have also agreed a similar procedure with the approval authorities responsible for the vehicles initially considered.”
However, despite there being no formal public announcement from the VW Group or the individual Audi and Seat brands, Autocar has learned that Seat raised CO2 emissions figures for 26 Ibiza and Leon derivatives just days after the original statement in mid-December, and that Audi followed suit just prior to Christmas, raising figures on six Audi A1 derivatives. Since then, it has been revealed that four A4 and eight Q3 models are also affected.
The revisions were described by a spokesman as being uncovered as part of “normal conformity disciplines”, while Seat and Audi spokesmen highlighted that all of the changes were published in data lists as usual and communicated to both fleet managers and owners of the cars who had placed orders prior to the revisions.
