Emissions scandal
The Volkswagen Golf TDI was at the centre of the Volkswagen emissions scandal, sometimes referred to as Dieselgate or Emissionsgate, which came to light in 2015.
The scandal involved Volkswagen, Audi, and Porsche installing software on certain diesel vehicles that was designed to detect when the vehicle was undergoing emissions testing. This software then turned on the vehicles' full emissions controls only during the test, reducing the effectiveness of the emissions control system during normal driving. This resulted in cars that met emissions standards in the laboratory, but emitted nitrogen oxides (NOx) at levels up to 40 times the standard when driven normally.
The software, known as a "defeat device", was installed on Volkswagen, Audi, and Porsche vehicles with 2.0-liter and 3.0-liter diesel engines, including the Volkswagen Golf TDI. In the US, the initial batch of affected cars was estimated at 482,000, while worldwide, Volkswagen admitted that about 11 million cars were affected.
The scandal led to significant consequences for Volkswagen, including a loss of trust from customers and the public, as well as financial impacts. The company's shares lost value, and it set aside billions of euros to cover the costs of recalling and fixing the affected vehicles. Volkswagen also faced fines and penalties from various government entities, including the US Environmental Protection Agency (EPA) and the Department of Justice. Several Volkswagen executives were charged and sentenced to prison terms, and the company was sued by consumers and faced class-action lawsuits.
In terms of the impact on the Volkswagen Golf TDI specifically, it is difficult to say with certainty what the exact consequences were. However, given that the Golf TDI was one of the affected models, it is likely that there was a drop in its resale value, as well as potential performance and fuel efficiency impacts depending on the fixes implemented by Volkswagen. Additionally, consumers who owned the Golf TDI may have joined class-action lawsuits, and those who had sold their vehicles before the scandal became public may have still been eligible to participate in legal action.
