Volkswagen’s diesel scandal – which cost CEO Martin Winterkorn his job – hasn’t just tainted the brand, it’s affecting other German automakers as well. Last week, BMW was drawn into the topic when Auto Bild brought up an issue concerning the X3 xDrive20d model, which it said could be emitting up to 11 times the legal NOx limits during tests conducted by the International Council on Clean Transportation (ICCT).

That issue has since been cleared after Auto Bild made a clarification on the matter, but now it’s the turn of Daimler – Mercedes-Benz’s parent company – to bat. The corporation is refuting allegations made by non-government organisation Deutsche Umwelthilfe (DUH) that it has been manipulating emissions tests.

In a statement, Daimler categorically denied the accusation of manipulating emission tests regarding its vehicles, and said that a ‘defeat device’, which illegitimately reduces emissions during testing, has never been and will never be used at Daimler. It added that both its diesel and petrol engines meet and adhere to every legal requirement.


The DUH sent along seven questions regarding the issue, to which the company said none of the allegations apply to its vehicles. Daimler said that its engines were programmed to adhere to all legal requirements, and had no knowledge of measurements that indicated its vehicles did not meet legally-required standards.

It said that it is actively supporting the work being done within Europe and Germany to develop new testing methods – which measure emissions based on real driving conditions – and would be working closely and constructively with authorities in Germany, Europe and the United States.

Daimler also said that it is evaluating its legal options pertaining to the approach taken and the public assertions made by the DUH, so this one might well go into the courtroom before it is resolved.
