Bosch launched internal investigation into its involvement in dieselgate image

The German supplier said an internal inquiry is under going to investigate the company role into the Volkswagen diesel emissions scandal.

Robert Bosch announced that he is already looking into its own yard to uncover whether any of his employees were involved in Volkswagen’s scandal over the emissions cheating scheme. “The day after the allegation became public, I ordered an internal investigation,” Bosch CEO Volkmar Denner said. The company was cooperating with authorities and could not provide further details, he added. The US and German authorities are investigating the supplier over its role in Volkswagen’s scandal or if it had any knowledge about the scheme. Bosch is making the engine control module that adjusts how a vehicle cleans burned-up fuel before it is expelled as exhaust, and basic software for nearly all the four-cylinder diesel cars sold in North America, including by Volkswagen AG, BMW AG and Mercedes-Benz.

However, Bosch did not want to reveal its engine management software codes to prosecutors, as they are the result of years of development. “Why should we disclose this,” Denner said. “What do authorities want with this? It’s so complex that it is not feasible.” The company publicly defended the diesel technology, saying on many occasions that diesels are needed to help cut carbon dioxide emissions in the United States and Europe. “The diesel is an air cleaning machine,” Denner said.

Separately, Stuttgart-based Bosch released preliminary full-year earnings for 2015, saying its revenue rose 10 percent year-on-year to 70.6 billion euros (76.7 billion dollars) last year thanks to a 12 percent jump in sales from its mobility solutions division to 41.7 billion euros.
