Daimler AG (DAI.XE) said Monday that it is "reviewing the facts" and cooperating with Germany's motor transport authority KBA over a possible diesel-emissions issue.
German weekly Bild am Sonntag reported Sunday that the authority found Daimler's Mercedes-Benz GLK 220 CDI models, produced between 2012 and 2015, are equipped with a previously unknown software function that could allow the cars to dodge emissions tests. KBA could therefore require Daimler to recall about 60,000 vehicles in Germany, according to the newspaper.
KBA found that the function artificially delays the heating of engine oil so that legal nitrogen-oxide targets are met on the test stand, but that the function is turned off on the road, leading to much higher emissions, Bild am Sonntag said.
According to the report, the authority also found that Daimler is deleting the software function during voluntary software updates.
Daimler said it complies with the approval process agreed upon with the KBA when implementing the service measures. "The allegation that we wanted to hide something with the voluntary service measure is incorrect," it said.
