Berlin - A seven-month independent probe into the Volkswagen exhaust emissions affair has failed to find those responsible for the scandal that has engulfed the carmaker, officials close to the matter told dpa on Friday.
The US law firm Jones Day was appointed by the VW supervisory board last October to draw up a report into the scandal, which emerged last September when the carmaker admitted that it had cheated on emissions tests on about 11 million diesel models around the world.
But while Jones Day has narrowed the origins of the software used to manipulate the exhaust tests to a group of departments and individuals, it has been unable to reconstruct the chain of events that led to the development of the scam, the sources said.
The investigation's failure to unearth the source of the illegal manipulation of tests was despite around 450 investigators searching through a massive database representing more than 102 terabytes of information, or more than 40 times the size of the Panama Papers release.
