VW Progresses with Diesel Emissions Fix Proposal; CO2 Emissions Update

VW Progresses with Diesel Emissions Fix Proposal; CO2 Emissions Update

By Philly Murtha, December 10, 2015

In addition to the major diesel emissions cheating embroilment, Volkswagen Group (VW) now faces an acknowledged problem with understating fuel consumption and CO2 emissions for about 36,000 vehicles that include some Golf, Passat, and Jetta models with gasoline engines, according to Reuters and other media sites. Initially, VW thought the issue might affect as many as 800,000 vehicles.

In addressing fuel consumption and diesel emissions violations, VW Group’s supervisory board this week will present a public update on investigation results as it presents proposals for fixes in the U.S. and abroad. This week Audi brand’s CEO, Rupert Stadler, submitted a plan to use a software update to fix luxury diesel cars with the emissions defeat device, according to Automotive News and Reuters. He still has to report to the VW supervisory board, however, due to concerns from labor representatives about not making any modifications to the specified models’ engines.

Volkswagen’s progress in coming up with fixes for as many as 557,000 2.0- and 3.0-liter diesel-powered passenger vehicles (covering 13 Volkswagen, Audi and Porsche models*) in the U.S. for diesel emissions cheating software is being tracked by the U.S. Environmental Protection Agency (EPA) on its website. Currently, the EPA is working closely with the California Air Resources Board (CARB) to address diesel emissions violations and to test all current 2015-2016 VW light-duty diesel vehicles to screen for potential defeat devices.

Several other related news highlights include:
  • On Nov. 20, Volkswagen provided the EPA and CARB with its initial proposal for repairing nearly half a million vehicles with 2.0-liter diesel engines that are listed in the EPA’s Sept. 18 Notice of Violation. The EPA and CARB are reviewing the proposal. A response is due this month. For the bigger diesels, the automaker plans to submit for approval plans to change the software, known as an auxiliary emissions control device.
  • In November, VW Group U.S. sales fell 15% (-7.9% selling-day adjusted**), based on sales data collected by J.D. Power and auto forecasting partner LMC Automotive. On a selling-day adjusted basis, November VW brand sales sank 18.2% from a year ago, while Audi (+9.1%) and Porsche (+2.9%) gains failed to offset VW’s decline, partly due to the impact of the recent stop-sale of all 2.0-liter, 4-cylinder TDI vehicles as well as for the 3.0-liter V-6s.
  • VW Group in November also posted a video on YouTube of how it will fix some 8.5 million passenger vehicles in Europe with 1.6-liter and 2.0-liter diesel engines that are equipped with emissions cheating device software. Two steps are outlined: 1) An engine control system software update; and 2) Installing a “flow transformer” to determine how much fuel is injected into the engine. The 3.0-liter V-6 fix can be achieved with a software update.

Current details for owners of VW, Audi, and Porsche models with the diesel emissions cheating device software:

  • The EPA hasn’t yet issued a recall of the specific diesel models with the device.
  • Owners will be notified once VW, Audi, and Porsche remedial plans are approved by the EPA.
  • Owners are not responsible for the cost of repairs.
  • The automaker will be given a time frame to develop a plan and complete repairs.
  • It could take up to one year to come up with corrective actions, develop a plan, and issue recall notices.
  • Some states will require the affected model owners to show proof of repairs before issuing annual vehicle registration.
