The state of New Jersey claims in a new lawsuit that Volkswagen sold diesel vehicles equipped with software that deactivated on-board emission controls except during emissions testing.
The suit filed Friday in Hudson County alleges the auto maker violated state clean air standards as it sought to gain a greater share of the passenger vehicle market.
Acting Attorney General John J. Hoffman estimates more than 17,000 vehicles equipped with the software have been sold in New Jersey, including Audis and Porsches sold by Volkswagen.
The lawsuit claims Volkswagen violated New Jersey law by causing the emission control equipment not to operate and increasing pollution in the air including nitrogen oxide.
The suit seeks fines and restitution.
A spokesman for Volkswagen Group of America didn’t immediately return an email seeking comment.
