Dragged into the scandal: Bosch is trying to distance itself from the Volkswagen emissions scandal by stating that it 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."
DETROIT/WASHINGTON: A popular diesel engine management program used by several top automakers, including Volkswagen AG, was not preprogrammed to detect when a vehicle was undergoing laboratory emissions testing, according to the US Environmental Protection Agency and a former EPA official.
Instead, VW had the engine software modified to turn on the vehicle's emission control system when it was being tested in the lab, on a rolling test bed called a dynamometer, then turn it off when the vehicle was on the road, the EPA said.
