Daimler declines to comment on the 1 million vehicles figure, but said it is cooperating fully and transparently with the KBA and Germany's Transport Ministry.
"In addition, Daimler explains that with maximum processing speed and in cooperative transparency with the authorities, the applications in the engine control system objected to by the federal government are eliminated", Federal Transport Minister Andreas Scheuer said in a statement. According to an official statement by the ministry, selected Vito, C-Class and GLC models in Germany are involved in this recall.
German authorities have been cracking down on manufacturers since the Volkswagen Dieselgate scandal first besmirched the reputation of its domestically produced vehicles.
The company said it is co-operating with authorities.
"In our integrated emission control systems, there are several hundred functions interlocked with each other, which can not be considered independently from each other", a Daimler spokesperson told The Drive.
At the time of the allegations, FCA CEO Sergio Marchionne struck a similar tone to Daimler; both automakers said the emissions control devices were legal.

Daimler Chief Executive Dieter Zetsche said on Monday that the carmaker had found a technical solution for updating the software on its vehicles, and he therefore expected the company would avoid a fine. A year ago it retrofitted three million Mercedes diesel cars built since 2011, but did not call the exercise a recall.
Speaking with the American publication, Arndt Ellinghorst, analyst with Evercore ISI in London, said: "We don't see any evidence that Daimler was designing software to deliberately cheat on emission testing".
"The criticised software is part of engine management and so-called auxiliary emissions control devices [which can turn off emissions controls during driving for other reasons, such as to protect the engine]".
The Kraftfahrt-Bundesamt said 238,000 vehicles in the country have unauthorised software fitted and has demanded that they are fixed immediately by the auto maker.
The KBA has also hit VW-owned Audi and Porsche with emissions-related recalls this year, as well as BMW.
