The head of R&D for German luxury car brand Audi is the latest to fall as the investigation into parent Volkswagen AG’s diesel emissions scandal moves forward.
An outside investigation commissioned by VW found that Stefan Knirsch, who also served as an Audi board member, knew about efforts to rig diesel engines with a so-called “defeat device,” and then lied about the subterfuge under oath. His suspension, first reported by German newspaper Bild am Sonntag, comes about a week after a U.S.-based Volkswagen engineer became the first company official to plead guilty as part of an expanding investigation by the Justice Department.
Separately, Justice investigators have begun probing the role of some Volkswagen suppliers, notably including German partsmaker Bosch, to see if they also participated in – or were at least aware of – the emissions test-rigging efforts. Bosch, is high on that list, according to a report by the Bloomberg News Service, as one of the suppliers of emissions technology, including software.
