| re: VAG's emission fraud - VW cheats in emission test VW problems may get even worse as authorities are investigating other VW models , per NY Times. article Quote:
Volkswagen said on Thursday that it was investigating whether substantially more vehicles than previously disclosed were equipped with software intended to deceive emissions tests, raising the possibility of even greater damage to the company’s reputation and finances.
The automaker admitted last month that 11 million cars and light commercial vehicles equipped with a diesel motor line known as the EA 189 had the illegal software. On Thursday, Volkswagen said it was investigating whether some versions of another diesel motor line, known as the EA 288, also had software intended to detect when a vehicle was undergoing emissions testing and turn on pollution controls.
Under normal road use, the EA 189 vehicles, which included popular models like the Passat, Jetta, Beetle and Golf, could emit up to 40 times the allowed amount of nitrogen oxide, a pollutant linked to numerous lung ailments.
A Volkswagen spokesman would not comment on how many more cars might be affected. Since 2012, the EA 288 has been installed in vehicles like the best-selling Golf, suggesting that the number of additional cars could be in the millions. The EA 288 was also installed in cars sold in the United States.
A company spokesman said that the newest versions of the motor, which are certified according to the latest European diesel emissions standard, are compliant with emissions rules and do not have illegal software.
Under pressure from German authorities, Volkswagen is recalling about 8.5 million European vehicles with the EA 189 motor to bring them into compliance with emissions regulations. Volkswagen has also promised to fix about 500,000 diesel cars in the United States.
Matthias Müller, the Volkswagen chief executive, said this month that the cost of repairing the vehicles would far exceed the 6.5 billion euros, or about $7.4 billion, the company initially allocated for recalls. If many more vehicles are affected, the expense to Volkswagen could rise significantly.
Not only would Volkswagen have to repair more cars, but it would also face more lawsuits from customers whose vehicles have lost value, or who contend that they were sold cars under false premises. Volkswagen marketed its “clean diesel” vehicles as an environmentally responsible choice for buyers who also wanted peppier performance than they would get from a hybrid competitor, like the Toyota Prius.
On Wednesday, Volkswagen said it had halted the sale of what it called a limited number of new cars with EA 189 motors from 2015 or earlier that were already at dealerships but had not been sold.
A 2-liter, four-cylinder version of the EA 288 was installed in Golf, Jetta and Passat cars sold in the United States beginning in 2012, according to an article on the website of Car and Driver magazine. The motor was more powerful than the EA 189, the magazine said, and treated emissions partly by recycling some exhaust gases into the motor. In addition, like the EA 189, the motor had a system to inject the chemical urea into the exhaust, which if designed properly could neutralize most of the nitrogen oxide emissions.
In treating some emissions by recycling them, the engine would have placed less of a burden on the chemical system, and owners would not have had to refill a urea supply tank as often. But the recycling system can also hurt acceleration and fuel economy. Volkswagen could have been motivated to dial back the pollution controls, except during testing, to give drivers better fuel consumption and performance, engineers outside the company have said.
In Internet forums, Volkswagen drivers often reported better fuel performance than in official government ratings.
Volkswagen could have saved fuel or improved performance by allowing more pollutants to pass through its cars’ exhaust systems, researchers said.
EA stands for “entwicklungsauftrag,” or “development order,” and signified a major new engine line. Volkswagen deploys its engines and other components not only in Volkswagen cars, but also in other brands belonging to the company, like Audi or Skoda. The strategy saves money because costs of development and production are spread across a large number of vehicles. But it means that any problems infect a large number of vehicles.
The engines were configured in different ways depending on the vehicle, further complicating the task of bringing them into compliance. According to Car and Driver, there was also a 1.6-liter version of the EA 288 that was not sold in the United States.
Volkswagen has said that in some cases, the cars can be fixed by reprogramming the software. But in other cases, Volkswagen may need to install new hardware, like systems to inject chemicals into the exhaust to neutralize nitrogen oxide emissions. Mr. Müller, the Volkswagen chief executive, has not ruled out giving some customers new vehicles if repairs are not possible.
Volkswagen has suspended five high-ranking executives in connection with the scandal. Mr. Müller has said that a small number of employees were responsible for the illegal software.
Determining how many people were in the know is one of the main goals of an internal investigation being conducted by Jones Day, an American law firm with offices in Germany. The investigation is still in its early phases and it is not clear how many managers, engineers and others may eventually be implicated, but the number is expected to rise.
At the very least, employees with knowledge of software coding would have to have been involved in order to program the motors to cheat. Source |
