1. What Was the US Car Maker Diesel EPA Fixing Software Scandal About?

The US car maker diesel EPA fixing software scandal, primarily involving Volkswagen (VW), centered on the use of “defeat devices” within the engine control units (ECUs) of diesel vehicles. These devices were designed to detect when a vehicle was undergoing emissions testing and would activate full emissions controls only during those tests. Outside of testing conditions, the emissions controls were significantly reduced, leading to nitrogen oxide (NOx) emissions up to 40 times higher than permitted levels. According to the Environmental Protection Agency (EPA), this constituted a violation of the Clean Air Act (CAA).

1.1. How Did Volkswagen Violate the Clean Air Act?

Volkswagen violated the Clean Air Act by:

• Using Defeat Devices: Installing software that altered emissions controls during normal driving conditions.
• False Certification: Certifying vehicles to the EPA as compliant when they were not.
• Excessive Emissions: Allowing vehicles to emit pollutants far above the legal limits during regular use.

1.2. Which Car Models Were Affected by the Software?

The affected models included approximately 499,000 diesel passenger cars sold in the United States since 2008:

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

1.3. What Were the Health and Environmental Impacts of the Excessive Emissions?

Excessive NOx emissions contribute to:

• Nitrogen Dioxide (NO2): A respiratory irritant that can exacerbate asthma and other respiratory conditions.
• Ground-Level Ozone: A major component of smog, which can cause lung damage and respiratory problems.
• Fine Particulate Matter: Tiny particles that can penetrate deep into the lungs and bloodstream, leading to cardiovascular and respiratory diseases.

Exposure to these pollutants can lead to:

• Increased asthma attacks
• Other respiratory illnesses
• Premature death due to respiratory or cardiovascular effects

According to the EPA, children, the elderly, and people with pre-existing respiratory diseases are particularly vulnerable.

2. How Was the US Car Maker Diesel EPA Fixing Software Detected?

The detection of the defeat devices was a multi-stage process involving independent research and regulatory scrutiny.

2.1. What Role Did West Virginia University Play in Uncovering the Issue?

Researchers at West Virginia University, working with the International Council on Clean Transportation (ICCT), conducted independent analysis that raised questions about the emissions levels of VW diesel vehicles during real-world driving conditions compared to laboratory testing. Their findings indicated significantly higher NOx emissions outside of test settings.

2.2. How Did EPA and CARB Investigate Volkswagen’s Alleged Actions?

Following the initial findings, the EPA and the California Air Resources Board (CARB) launched further investigations. They demanded explanations from Volkswagen regarding the identified emission problems. In September 2015, VW admitted that the cars contained defeat devices.

2.3. What Specific Software Algorithms Were Used as Defeat Devices?

The software algorithm was designed to recognize when the car was undergoing official emissions testing. During these tests, the algorithm would activate full emissions controls, ensuring compliance with EPA standards. However, during normal driving conditions, the emissions controls were significantly reduced, leading to higher NOx emissions.

3. What Were the Legal and Regulatory Consequences for Volkswagen?

Volkswagen faced significant legal and regulatory consequences as a result of the diesel emissions scandal.

3.1. What Penalties and Fines Did Volkswagen Face from the EPA?

VW may be liable for civil penalties and injunctive relief for the violations alleged in the NOV. The exact amount of the penalties would depend on further legal proceedings and negotiations. The penalties could be substantial, given the scale of the violations and the number of vehicles affected.

3.2. How Did the Scandal Affect Volkswagen’s Reputation and Market Value?

The scandal had a severe impact on Volkswagen’s reputation and market value. The company faced:

• Damage to Brand Image: The scandal eroded trust in the Volkswagen brand, which had long been associated with quality and environmental responsibility.
• Decline in Sales: Sales of VW vehicles declined in the aftermath of the scandal as consumers lost confidence in the brand.
• Stock Price Drop: Volkswagen’s stock price plummeted as investors reacted to the news of the violations and the potential financial liabilities.

3.3. What Steps Did Volkswagen Take to Rectify the Situation?

Volkswagen took several steps to rectify the situation, including:

• Recalls and Repairs: Initiating recalls of affected vehicles to update the engine control software and hardware to ensure compliance with emissions standards.
