German Transport Minister Alexander Dobrindt announced Wednesday that all current models sold under the VW, Audi, Skoda and Seat brands would be tested for carbon dioxide and nitrogen dioxide emissions, affecting both diesel and petrol vehicles.
The move came after another Volkswagen unit, Porsche, halted sales of its Cayenne diesel sport utility vehicles following the new allegations from the Environmental Protection Agency.
The embattled company also admitted Tuesday it set carbon dioxide emissions and fuel consumption figures too low when certifying about 800,000 vehicles.
