FRANKFURT AM MAIN

German luxury automaker Daimler manipulated the engines of around one million diesel vehicles to make them appear less polluting, local media reported on Thursday, raising echoes of competitor Volkswagen’s ‘dieselgate’ scandal.

“The Stuttgart-based firm sold vehicles with higher levels of damaging emissions than allowed for almost a whole decade between 2008 and 2016, in Europe and the United States,” daily Sueddeutsche Zeitung said.

Along with regional broadcasters NDR and WDR, the newspaper had access to a search warrant from a Stuttgart court allowing prosecutors to raid 11 sites belonging to the Mercedes-Benz and Smart maker in late May.

Investigators suspect that the world’s largest luxury carmaker used a similar so-called “defeat device” to Volkswagen, which in 2015 admitted to manipulating emissions readings on some 11 million diesel vehicles worldwide.

Software in the motor runs the emissions treatment system at a higher setting when it detects the vehicle is undergoing regulatory testing.

Investigators believe cars fitted with the OM 642 and OM 651 engines filter out 95-99 per cent of harmful nitrogen oxides under test conditions, but only between 35 and 85 per cent in real on-road driving.

The motors were built into more than one million cars and vans by Daimler, including C, E and R class Mercedes.

A Daimler spokeswoman contacted by AFP declined to comment on an ongoing investigation, but said the carmaker was cooperating with the authorities.

Prosecutors reiterated that two employees from the team that created the software are under formal investigation on suspicion of fraud and false advertising, neither of them senior executives.

Shares in Daimler AG were one of the worst performers on Germany’s blue-chip DAX index Thursday morning, losing 0.95 per cent to trade at 64.84 euros ($73.94) by 1010 GMT, against a market up 0.33 per cent.

Initial suspicion

“We have always said that there is an initial suspicion of manipulation in emissions treatment of diesel engines from Daimler,” a spokesman for the Stuttgart prosecutors’ office said.

According to the warrant, prosecutors sought to recover emails between 99 Daimler employees during the raids in May, one of them a member of the group’s executive board.

The document suggests that officials believe more people were involved than the two presently targeted, and expect suspects will be added to the probe.

Daimler also faces an investigation by the United States Department of Justice, as well as a number of class-action lawsuits in the US accusing it of false advertising.
