schwit1 writes: Just a day after news broke that Volkswagen's emissions scandal had expanded to its Porsche unit and Audi SUVs, the company has disclosed yet another problem, this time affecting carbon dioxide levels emitted by their cars. "Volkswagen said an internal probe showed 800,000 cars had "unexplained inconsistencies" concerning their carbon-dioxide output. Previously, the automaker estimated it would need to recall 11 million vehicles worldwide — more than Volkswagen sold last year." This batch of cars includes a small number of gasoline engines. Until now, only diesel engines were part of the problem.
