Volkswagen has announced details on how it plans to fix both 1.6- and 2.0-liter diesel engines in Europe.
Both of these EA 189 engines will require a software fix, while the 1.6-liter also needs the addition of a “flow transformer,” essentially a mesh screen that is fit in front of the air sensor to help calm the air which should allow the sensor to more accurately measure airflow. The software fix for the 2.0-liter should take about 30 minutes according to the company, while work on the 1.6-liter engine will take about an hour.
For now, this plan is only for European cars, but this exact same fix may be used here in the U.S. Volkswagen has already submitted its plan to fix American cars to the Environmental Protection Agency and the California Air Resources Board, but details on that plan are still in the dark.
Volkswagen is assuring its customers that fuel economy and powertrain performance would not be affected by the fixes, though VW also says that testing on the revised cars has not been completed. Next month, VW will detail its fix for the 1.2-liter, three-cylinder diesel engine that is fitted to many of its European cars.
The brand has already pledged to fix all 11 million of its vehicles worldwide that are fit with software that deliberately cheats emissions tests.
