The suspicion that if the brand had fitted these devices to one type of engine, they could certainly have installed them inothers, was confirmed this week when 3.0-litre V6 turbodiesel engines from the years 2014-2016 were allegedly found to have the emissions cheating software installed, according to the United States Environmental Protection Agency(EPA).
The latest allegation from the EPA includes another brand, namely Porsche, in addition to Audi and Volkswagen. The models affected by the claim are 2015 Porsche Cayennes, 2014 VW Touaregs and Audi models such as the A6, A7, A8/A8L and the Q5.
The VW Group has produced over 1.6 million of these V6 engines and the EPA has only tested certain model years, claiming some 10 000 vehicles are affected. It is unclear as to whether this number will increase as the investigation continues.
However, the Volkswagen Group is less apologetic this time around and more defensive, claiming that this software was not installed, that lowered the vehicles’ emissions during test scenarios.
The EPA, in its press release titled, “California Notify Volkswagen of Additional Clean Air Act Violations” has stated that, “The Notice of Violation (NOV) alleges that VW developed and installed a defeatdevice in certain VW, Audi and Porsche light duty diesel vehicles equipped with 3.0-litre engines for model years (MY) 2014 through 2016 that increases emissions of nitrogen oxide (NOx) up to nine times EPA's standard.
"VW has once again failed in its obligation to comply with the law that protects clean air for all Americans," said Cynthia Giles, Assistant Administrator for the Office for EPA's Enforcement and Compliance Assurance.
"On September 25, the California Air Resources Board sent letters to all manufacturers letting them know we would be screening vehicles for potential defeat devices," said Richard Corey, Executive Officer of the California Air Resources Board. "Since then ARB, EPA and Environment Canada have continued test programmes on additional diesel-powered passenger cars and SUVs. These tests have raised serious concerns about the presence of defeat devices on additional VW, Audi and Porsche vehicles. Today we are requiring the VW Group to address these issues. This is a very serious public health matter. ARB and EPA will continue to conduct a rigorous investigation that includes testing more vehicles until all of the facts are out in the open," explained Corey.
The pressure is mounting in Wolfsburg as Volkswagen is placed under the microscope with the second allegation. Here at Autodealer we don’t see this problem disappearing for the auto giant for the foreseeable future.
