We recently spoke about the fact that Audi’s 3.0 liter V6 TDI engine had also been cheating emissions, along with the 2.0 liter TDI engines that we already knew about. This was a big blow to Volkswagen, Audi and even Porsche, as all three companies use that engine in various automobiles. When we first heard of this news, it seemed as if it was going to cost Volkswagen billions extra to fix. It turns out that Audi may have found a fix that won’t cost nearly as much.
Audi has just reported that it has developed a software fix for its 3.0 V6 TDI engines that will clean up the engines’ emissions to regulation levels. Seeing as how this “defeat device” that was installed on the engines was software related, it isn’t surprising that a software fix can make it all better. However, we’ve yet to see if it will actually work or not.
Audi is going to have to reapply with the US EPA (Environmental Protection Agency) and the CARB (California Air Resources Board) before it can implement this software fix. If the EPA and CARB sign off on the software update that Audi is proposing, than it’s likely Audi will begin to recall all vehicles with that engine as soon as possible to get this scandal sorted. However, until the EPA signs off on this, Audi has stopped sales of all 3.0 V6 TDI engined vehicles.[Source: Road & Track]
