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.

Liar liar. If the solution was so simple, why didn’t you implement it in the first place. Clearly there will be some trade off somewhere
Why is it that bashers’ language comprehension skills are going down the toilet? Is it from lack of understanding of English grammar, or simply a lack of brains?
The affected models had a non-compliant defeat device installed. In this case, a unit that alters the temperature of the catalytic converter. A software fix would just either disable this mechanism, or enable it to work with the engine management in a way which minimizes NOx emissions without having it to be turned on all the time.
The fix DOES NOT enable the cars to operate with the earlier-claimed NOx emission levels. The fixes implemented by the VW group are aimed at eliminating the use of defeat devices, in combination with some method to keep NOx emissions at reasonable levels. They will have to declare their actual NOx emission levels too, which would make them non-Euro 5 or Euro 6 compliant.
If the software fix disables the defeat device and the vehicle now emits NOx at more than the EPA standard, how is that a solution?
It’s like you got caught for lying about stealing so now you admit to stealing but you still stole.
As I see it, you’re the idiot here. Clearly a VW die hard fan/cybertrooper
Pretty sure the performance gonna be lower
I have a simplest solution to VW and the gang….just re-print your actual emission value in all your catalogue. Then it will fixed your compliance test, right?
