The public prosecutors’ office in the city of Stuttgart has opened an official investigation involving three mid-level managers at the auto components supplier Bosch over their possible involvement in the Volkswagen diesel emissions scandal, a spokesperson for the office confirmed Thursday.
Bosch, based in the town of Gerlingen near Stuttgart, supplied the engine control device that houses the software used by VW to manipulate diesel emissions during tests. Bosch has categorically denied any wrongdoing, insisting that it simply made the components according to Volkswagen’s specifications and was not responsible for how they were used.
The investigation and possible prosecution of individual employees at Bosch marks a potential new phase in the larger probe of diesel emissions cheating at Volkswagen. Prosecutors say the Bosch employees are under initial suspicion of aiding and abetting fraud in connection with manipulation of emissions in Volkswagen vehicles. It is possible that other employees of Bosch will be added to the investigation as the probe continues.
