WOLFSBURG, Germany (Reuters) -- Volkswagen rigged emission tests on about 2.8 million diesel vehicles in Germany, German Transport Minister Alexander Dobrindt said on Friday, nearly six times as many as it has admitted to falsifying in the United States.
His comments, pointing to cheating on a bigger scale than previously thought, deepened the crisis at VW as its supervisory board held a crucial meeting.
"It's now clear that vehicles in Germany are affected by these manipulations. Based on our current knowledge they are vehicles with 2.0-liter and 1.6-liter diesel engines," Dobrindt told Germany's Bundestag lower house of parliament.
Dobrindt also said there was a possibility of 1.2-liter diesel engines being affected too.
VW said this week that irregularities on diesel-emission readings extend to 11 million vehicles globally with Type EA 189 engines.
Germany’s motor-vehicle certification bureau has asked VW for "a binding statement on whether the company can redress the technical manipulations it has acknowledged so the vehicles can be returned to a condition that meets technical regulations,” said Dobrindt, who set up a government investigating commission this week after VW’s actions came to light.
Volkswagen "has pledged full support for the commission’s work and to cooperate in the investigation," he said.
Regulators and prosecutors across the world are investigating the scandal.
The European Commission has urged all EU member states to investigate into how many cars use illegal "defeat" devices to cheat emissions tests in light of the Volkswagen admission.
France will carry out testing on its roads to establish whether vehicles are equipped with banned software of the kind used by VW. Italy will test 1,000 cars from all the VW brands sold nationally, its transport minister said.
