According to Reuters reports, the Daimler Benz management board has approved measures to cut diesel pollution, including an investment of € 220 million "to update over three million Mercedes-Benz diesel engine cars" in Europe.
The measures come after German lawmakers last week summoned Mercedes-Benz executives to question them about emissions. At the time the car maker agreed with the Transport Ministry to undergo another round of emissions tests.
"The company is investing about 220 million euros. The service actions involve no costs for the customers," Daimler said in a statement on , adding that the updates would commence in the coming weeks.
After Volkswagen confessed to deliberate emissions cheating in 2015, the entire car industry has come under scrutiny for producing nitrogen oxide emissions in diesel cars, which are blamed for causing respiratory disease.
In May, 23 prosecutors and around 230 staff, including police and state criminal authorities, searched Daimler sites in Germany following allegations of false advertising and the possible manipulation of exhaust gas treatment systems in diesel cars.
Daimler has said its vehicles are road legal but also warned investors in its quarterly report that steps by U.S. authorities to investigate "functionalities", including some which it said were common in diesel vehicles, could lead to significant penalties and vehicle recalls.
Last week executives from Daimler were questioned by German MP's about emissions and the company said then that it was undertaking "another round of tests".
The Irish distributor for Mercedes is awaiting information from Germany on the scale of the recall here.
