Confident in his technologies, PSA Group is fully cooperating with the authorities" the group said.There was no comment from the DGCCRF.Reacting to revelations in 2015 from German carmaker Volkswagen that it had used software to cheat on emissions tests, France launched investigations into its own car industry.
