German prosecutors said Friday they have arrested a former employee of the Volkswagen unit Audi in connection with the company's diesel scandal.
The office of the prosecutors of the city of Munich said the man worked in engine development in southern German city of Neckarsulm and is accused of fraud and unfair advertising.
The prosecutors did not confirm whether the individual was Giovanni Pamio, who was accused Thursday by U.S. authorities of giving the orders to program diesel engines to cheat on emissions tests.
Pamio, 60 and an Italian citizen, is a former Audi executive and based in Neckarsulm.
He's the eighth former Volkswagen employee charged in the case that is being investigated by the FBI and the Environmental Protection Agency's criminal unit. One of the employees is scheduled for sentencing this month, another is in custody in the U.S. and five others are German citizens.
Volkswagen has admitted that its Volkswagen, Porsche and Audi vehicles with 2-liter and 3-liter diesel engines were programmed to turn pollution controls on during government treadmill tests and turn them off while on the road. The scheme went on for years before being discovered in tests conducted by West Virginia University. The scandal has cost Volkswagen more than $20 billion in criminal penalties and lawsuit settlements.
According to a criminal complaint filed Thursday in Detroit, Pamio is charged with conspiracy, wire fraud and violating the Clean Air Act.
The U.S. Attorney's Office said Cleveland attorney Terry Brennan was representing Pamio. Brennan would not comment when reached Thursday evening.
The complaint says Pamio was head of Thermodynamics in Audi's Diesel Development Department in Neckarsulm, leading a team of engineers who designed emissions controls from 2006 through November of 2015.
He and other unidentified conspirators determined it was impossible to calibrate a 3-liter diesel engine to meet U.S. nitrogen oxide emissions standards within design constraints imposed by other VW departments. So Pamio "directed Audi employees to design and implement software functions to cheat the standard U.S. emissions tests," the U.S. Attorney's Office said in a statement.
Pamio and others then failed to disclose the software and knowingly misrepresented that the engines complied with U.S. pollution standards, according to the complaint.
In 2008, engineers who designed the cheating system sent a presentation to Audi senior management, including Pamio, that detailed it, according to the complaint. That year, several Audi managers concluded the software was "indefensible." An Audi manager in 2013 sent an email about discussing the system with U.S. regulators, but Pamio, the complaint stated, argued that disclosure would be "too risky!"
Volkswagen already has pleaded guilty to criminal charges and agreed to pay a $2.8 billion penalty.
