Volkswagen (VOWG_p.DE) denied a report on Saturday that its sales have slumped since this month’s admission that it had understated the level of carbon dioxide emissions for some cars. German daily Frankfurter Allgemeine Zeitung (FAZ) had reported earlier on Saturday that Volkswagen’s sales were declining significantly, citing an unnamed dealer as saying business was “dead as a doornail”. “We cannot confirm the statement quoted in FAZ,” a spokesman for Volkswagen told Reuters in an e-mailed statement.
