VW Submits Plan to Fix 3.0-liter Diesel Engine Emissions Cheating Devices

VW Submits Plan to Fix 3.0-liter Diesel Engine Emissions Cheating Devices

By Philly Murtha, February 06, 2016
Volkswagen Group this week submitted a plan to California air regulators and the U.S. Environmental Protection Agency ( EPA) for recalling and fixing thousands of Audi, Porsche, and VW vehicles in the United States equipped with 3.0-liter diesel engines that contain illegal “defeat device” software that misstates NOx exhaust emissions, according to Reuters.

The new plan is supposed to make the following diesel-powered vehicles compliant with clean air requirements: 2009-2016 Volkswagen Touareg; 2013-2016 Porsche Cayenne; and 2014-2016 Audi A6 Quattro, Audi A7 Quattro, Audi A8, Audi A8L, Audi Q5, and 2009-2016 Audi Q7. Currently, Volkswagen is barred from selling 2016 diesel models in the United States.

Last month, the California Air Resources Board (CARB) rejected VW’s proposal to fix 482,000 vehicles with 2.0-liter diesel engines, stating that the plan was incomplete and lacked detail. Any plan submitted will be tested by California regulators and EPA technicians before approval and roll-out to VW Group car owners with affected non-compliant diesel-engine vehicles.

Auto enthusiast publication AutoWeek reports that the fixes may be more complex in the U.S., as “several versions of the EA 189 engine featured in U.S. models since 2009 will require different solutions, with some needing hardware as well as software updates.” One proposed fix is to install a new type of catalytic converter.

On Feb. 5, VW Group announced that it will delay publishing annual earnings results and also pushed back its March 10 shareholders meeting due to unknown financial costs of dealing with the diesel-emissions cheating software debacle, Bloomberg News reports. The automaker has set aside $7.5 billion to cover repair costs for 11 million vehicles globally. In related news, the German auto group plans to publish in April results from an investigation of how the installation of the illegal “defeat device” happened.

Meanwhile, in Europe, VW has received approval from European Union regulators to begin fixing 8.5 million vehicles with the emissions cheating software, according to VW Group. Engine-control software updates will be installed on vehicles with 2.0-liter diesel engines, beginning with the Amorak pickup followed by the Passat. Repairs for vehicles with 1.6-liter diesel engines, including installation of a “flow transformer,” should start in the third quarter. A technical fix for vehicles with 1.6-liter diesel engines still needs to be presented for approval to EU regulators at the end of the month.

To date, VW Group models that have been recalled by the EPA to be fixed and made compliant are:

2.0-liter diesel models:

  • Volkswagen Jetta (2009-2015) and Jetta Sportwagen (2009-2014)
  • Volkswagen Beetle and Beetle Convertible (2012-2015)
  • Audi A3 (2010-2015)
  • Volkswagen Golf (2010-2015) and Golf Sportwagen (2015)
  • Volkswagen Passat (2012-2015)

3.0-liter diesel models:

  • Volkswagen Touareg (2009-2016)
  • Porsche Cayenne (2013-2016)
  • Audi A6 Quattro (2014-2016)
  • Audi A7 Quattro (2014-2016)
  • Audi A8 (2014-2016)
  • Audi A8L (2014-2016)
  • Audi Q5 (2014-2016)
  • Audi Q7 (2009-2016)
