Volkswagen AG told European Union finance ministers on Friday that the German car maker would foot the bill for additional taxes due on a number of cars affected by the company's emissions cheating, a move that could set a precedent for U.S. regulators and car dealers who want VW to make their customers whole in the wake of the emissions scandal. In its latest disclosure in the widening emissions crisis, Volkswagen said earlier this week that it understated greenhouse gas emissions and fuel consumption on around 800,000 cars, mostly in Europe.
