EPA approves Volkswagen software fix for 2.0 TDI engines

In light of the diesel rescue plan in Germany, Volkswagen is making headway with fixing the cars fitted with defeat devices. In the U.S, the Environmental Protection Agency (EPA) has approved Volkswagen's software fix for specific TDI-powered cars. The revamped engine management system will be for the 2.0-liter, four-cylinder versions.

“VW will remove the defeat device software that reduced emission control effectiveness in all but emissions testing circumstances, and replace it with software that directs the emission controls to function effectively in all typical vehicle operations,” said the EPA. Similar to Audi's fix for V6 and V8 TDI engines in Germany, Volkswagen will be notifying U.S customers that the new software can now be installed in their cars and the service will be free of charge.

The cars that can be fitted with the new engine management system are the Jetta, Golf, Beetle TDI models, as well as the Audi A3 TDI. These cars will also be installed with a new NOx catalyst and, for 2009 vehicles, various parts for the emissions-control system. Customers also have the option of selling back their affected cars to Volkswagen.

It was a long road for Volkswagen for them to find a repair for the affected cars. Earlier this year, the EPA rejected the German automaker's proposal for the new software. “This important milestone means that an approved emissions modification is now available for more than 98 percent of eligible 2.0L TDI vehicles in the United States,” said Volkswagen in their statement.

As for TDI V6 and TDI V8-powered models, a new software has yet to be approved by the EPA.
