US authorities are investigating German auto supplier Bosch GmbH over its role in Volkswagen AG’s massive scheme to cheat emission standards, sources told Reuters. The ramifications of the cheating scandal extend in all directions, as federal prosecutors with the US Department of Justice are inquiring Bosch GmbH. The authorities are investigating if the German auto supplier was involved in Volkswagen’s cheating scheme or if it had any knowledge about it. This new revelation has been brought to light by people familiar with the matter, told Reuters. 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. The US prosecutors have not found so far evidence of Bosch’s direct involvement, sources said. But it is not clear what role the supplier played, how closely it worked with VW to modify the engine management software and how much it knew about VW’s intentions to use software to bypass the emissions controls. BMW and Daimler have denied using that cheating device. Bosch previously told Reuters that the company supplies components such as engine management systems to automakers’ specifications, and that “how these components are calibrated and integrated into complete vehicle systems is the responsibility of each automaker. Volkswagen has admitted to installing the modified software which turned on the vehicle’s emission control system when it was being tested in the lab, then turned it off when the vehicle was on the road, according to US regulators. Neither party wanted to comment on the matter. Via Reuters
