More Volkswagen vehicles have emission-cheating devices

The new disclosure covers a total of 85,000 vehicles, the EPA said.

Audi’s announcement follows a meeting last week between the automaker and regulators where changes were discussed.

Embattled manufacturer Volkswagen has submitted what it claims is a fix for its controversial diesel powertrains to the US Environmental Protection Agency (EPA), and California Air Resource board. According to a statement released by Audi, the updated software will be installed as soon as it is approved by the authorities.

The upscale brand of embattled German auto giant Volkswagen “estimates that the related expense will be in the mid-double-digit millions of euros”, the company said in a news release. The engine was also used in the VW Touareg and Porsche Cayenne SUVs since model year 2013, Audi said.

Before Friday, the EPA’s investigation involved only some of those larger-engine models from VW, Audi and Porsche from 2014-2016, along with 482,000 vehicles with 2-liter diesel engines from the 2009-2015 model years. The agency revised the…

The probe extends the reach of the scandal from VW’s headquarters in Wolfsburg, Germany, to Audi, the Bavarian luxury-car unit that also builds engines for Porsche.

“Volkswagen AG wishes to emphasize that no software has been installed in the 3-liter, V6 diesel-power units to alter emissions characteristics in a forbidden manner”, the company said in a statement.

Two of the AECDs prevent deposits on the metering valve for urea liquid, and prevent poisoning the catalyst in the Selective Catalytic Reduction system with hydrocarbons from unburnt fuel. Called auxiliary emissions control devices, the automaker said that one of the three was the “defeat switch” that has been cited as central to the emissions scandal.

The technology at issue is software that adjusts the temperature of the exhaust system, Ward said. Previously the with 2-liter four-cylinder engines were caught cheating emission tests. VW has told dealers not to sell any of the models until the software is fixed.

Volkswagen’s 2.0-liter diesel engine was the first ones to have been discovered with that behavior, causing the scandal and fallout that is rocking one of the world’s biggest auto makers.

Audi agrees that it will need to come up with additional measures that satisfy the regulators, Ward said.
