According to the magazine, a judge asked Bosch to provide various documents to the relevant chamber. However, the auto parts supplier refused to surrender and relied on the right to refuse to give evidence.
Bosch had supplied VW with basic versions of a software for engine control and emission control. Because the program was possibly used by the car manufacturer to manipulate nitrogen oxide levels, the Stuttgart prosecutor also investigates Bosch employees.
In the US, where the VW emissions scandal became known in September 2015, procedures are also underway. The documents requested in Stuttgart are, according to information from the “mirror”, among others, emails between employees of Bosch and Volkswagen in 2007.
