Germany's Volkswagen is already in a whole heap of global trouble after the car maker was caught cheating on U.S. tests for nitrogen oxide emissions. Then, we learned "Dieselgate" also involved VW subsidiary brands Audi and Porsche.
Now it gets worse. Today VW announced that an internal investigation has revealed "unexplained inconsistencies" in the carbon dioxide emissions from some 800,000 vehicles.
The company warned Tuesday it estimated the possible "economic risks at approximately 2 billion euros" due to the new problem.
It did not identify which vehicles were affected, but said the flaw in no way compromised the safety of any of the vehicles.
The statement says the company will "will endeavor to clarify the further course of action as quickly as possible and ensure the correct CO2 classification for the vehicles affected" with the responsible authorities.
"VW's top management will immediately start a dialogue with responsible authorities regarding the consequences of these findings," a VW spokesperson said.
