VW chiefs 'hushed up emission cheating'
By the summer of 2015, the complaint from the FBI said US regulators knew that emissions from VW diesel vehicles were "substantially higher" when they were being driven on the road than when being tested.
The affidavit said Mr Schmidt - who was the general manager in charge of VW's Environmental and Engineering Office between 2012 and March 2015 - knew the discrepancy was because VW had "intentionally installed software in the diesel vehicles it sold in the US from 2009 through 2015 designed to detect and cheat US emissions tests".
In 2015, Mr Schmidt travelled to the US to talk to US regulators about the discrepancy. The filing says that during these talks, Mr Schmidt "intended to, and did, deceive and mislead US regulators" by saying the difference in the emission levels was not because of deliberate cheating.
The affidavit cites two VW employees who said that in a presentation to VW's executive management in Germany, "VW employees [including Mr Schmidt] assured VW executive management that US regulators were not aware of the defeat devices - that is the engines' ability to distinguish between the dynamometer and road mode.
"Rather than advocate for disclosure of the defeat device to US regulators, VW executive management authorised its continued concealment. "
... in the UK, lawyers said 10,000 VW owners had already expressed an interest in suing VW. They estimated that owners could get "several thousand" pounds in compensation.
Harcus Sinclair is applying for a group litigation order - which is similar to a US class action lawsuit - in the High Court later this month
Seventy-seven current or former VW owners have put their names to Harcus Sinclair's application for a group litigation order which will be heard in the High Court on 30 January.
