A French investigation has alleged that the PSA Group (Peugeot, Citroen, DS, Opel) are using defeat devices in their cars to pass emissions. The investigation stated that 'suspicious software' was found in the cars and approximately two million vehicles are said to be affected. 

French watchdog Direction Générale de la Concurrence, de la Consommation et de la Répression des Fraudes (DGCCRF), sent their reports to French authorities back in February. French newspaper Le Monde stated that the DGCCRF was able to obtain internal documents making tampering software 'less obvious and visible'.

Peugeot was quick to respond to the allegations, stating that there are no defeat devices in their cars. In their statement, the PSA Group reaffirms that they comply with regulations in every country where it operates and its vehicles have never been equipped with software or systems making it possible to detect compliance tests and to activate a pollutant treatment device that would be inactive during customer use. PSA Group has repeatedly explained its strategy regarding engine settings which favors low nitrogen oxide (NOx) emissions in cities while ensuring the best NOx/ CO2 balance on open roads. Peugeot's real-world testing was conducted under the adjudication of Transport & Environment (T&E), France Nature Environment (FNE) and Bureau Veritas.

 PSA Group responds to allegations of emissions tampering

The company added that they have been doing real-world emissions testing in light of the Volkswagen emissions tampering scandal. On top of that, the PSA Group pointed out that they are the only automaker to publicly declare real-world emissions. Peugeot has readjusted their official emissions rating since then. They added that the 'group is outraged to learn that information has been provided to third parties whereas Groupe PSA has never had access to the file submitted by the DGCCRF to the public prosecutor's office, making it impossible for the group to put forward its arguments.'

The automaker is considering legal action, stating that the group 'reserves the right to file a complaint for breach of confidentiality of the investigation and the authorities’ confidentiality obligation'. Ever since the Volkswagen emissions scandal broke out in late 2015, several European automakers have come under fire from different governments. These include the Fiat Chrysler Group, Daimler and Renault-Nissan Alliance and General Motors.
