The legal action was initiated after in September 2015, US regulators accused Volkswagen of using software designed to falsify emission test results for its diesel-engine cars. The automaker admitted that 11 million diesel cars worldwide had been equipped with such pollution test cheating devices. In January 2017, Volkswagen confirmed that it had agreed on a draft $4.3 billion settlement with the United States to resolve the matter.
