According to Audi CEO, Rupert Stadler, the automaker has found a simple fix for vehicles equipped with the Volkswagen Group’s 3.0 litre TDI V6 engine that contain defeat devices, designed to foil emissions tests. In a report by Reuters, Stadler told a gathering of 7,000 workers at Audi’s Ingolstadt headquarters, “swift, straightforward and customer-friendly solutions are in discussion. Every day we are taking another step toward the solution.”

In November, it was revealed that around 85,000 vehicles from Volkswagen, Porsche and Audi were affected by the widening “Dieselgate” scandal. The affected models were said to carry auxiliary emission-control devices (AECD) in its engines, which are capable of adjusting the working temperature of the vehicle’s catalytic, deemed illegal by US authorities.

A notice of violation (NOV) issued by the US Environmental Protection Agency (EPA) stated that the 3.0 litre TDI V6 engine carried defeat devices that detect when vehicles are undergoing emissions testing. To meet emission standards, it would configure the engine to a low NOx temperature conditioning mode. However, once the testing is completed, the device reverts back to its “normal” setting, where emissions of NOx increase up to nine times the EPA standard.

Following this, the German carmaker claimed that it could repair the problem with just a software update. Stadler’s statement is an indication that such a simple fix might already be on the way. VW AG earlier revealed its fix for its EA189 four-cylinder TDI engines (1.6 and 2.0 litre capacities) at the end of November, which is more advanced that just a software update.
