VW diesel engine

More emissions defeat devices have been found in the Volkswagen Group’s 3.0 litre diesel engine, according to German weekly Bild am Sonntag, as quoted by Automotive News. The additional, unapproved software allows the turbodiesel to shut down emissions control systems after approximately 22 minutes in operation, the German weekly said. Official emissions measurements last about 20 minutes.

The 3.0 litre turbodiesel V6 engine mentioned earlier by the Environmental Protection Agency (EPA) as affected by the defeat devices is used in models such as the Volkswagen Touareg, Porsche Cayenne, Audi A6 quattro, A7 quattro, A8 and Q5. The earlier episode of the Dieselgate scandal was first uncovered with revelation of emissions defeat devices in the group’s 2.0 litre, four-cylinder turbodiesel engine.

That has led to the automaker potentially spending up to US$15.3 billion (RM61.6 billion) in buybacks of affected vehicles in the US, and funding for makers of cleaner technologies, though that move is unlikely to be replicated in the automaker’s home market of Europe due to cost. That settlement also does not cover the 85,000 vehicles with the 3.0 litre diesel engine found to have more defeat devices, and a deal for the 3.0 litre vehicles may still be months away.

Audi managers are scheduled to appear at a hearing in front of US environmental authorities on August 10, according to Bild am Sonntag, adding the the automaker is bracing for a substantial penalty payment for the most recent batch of affected vehicles. A spokesman for Audi only said talks with the US authorities are ongoing and are aimed at a technical solution for the problem.
