Audi details U.S. diesel models with ‘defeat device’ software

WASHINGTON — Audi of America has sold about 14,300 A3 compact cars powered by 2.0-liter turbodiesel engines with software implicated in Volkswagen AG’s emissions scandal.

An Audi of America spokesman said Tuesday that about 11,600 of those affected vehicles are 2010-13 model A3 TDIs powered by VW’s first-generation “clean diesel” engine. The engine, dubbed EA189, features a lean NOx trap to reduce nitrogen oxide emissions.

The remaining vehicles are 2015 A3 TDI models with Audi’s latest generation clean diesel engine, called EA288, which uses a urea injection treatment system to reduce harmful emissions.

Audi did not market a 2014 A3 in the U.S. The current-generation A3 went on sale as a redesigned 2015 model.

Audi said Monday that about 2.1 million vehicles it has sold globally are equipped with defeat device software intended to skirt emissions rules. Affected models overseas include the A4 and A6 sedans and Q3 and Q5 crossovers, but those models are not implicated in the United States. Other than the 2.0-liter in the A3 TDI, the only diesel engine in Audi’s U.S. lineup is a 3.0-liter V-6 diesel used on models such as the A6, Q5 and Q7, which has not been implicated in the scandal.

The Audi spokesman had no information about when a plan to repair the A3 TDIs would be presented to customers but said the company is working “to get in front of the EPA and California Air Resources Board as soon as possible.”
