New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

German prosecutors raid VW, Audi offices

As Volkswagen continues to try to put its diesel emissions scandal behind it, the company has had mixed success. It has agreed to pay penalties and fix or buy back affected vehicles in the US, and has made a strong push to evolve into a greener, mobility-focused company. The scandal just won't die, though, and has, in fact, just escalated. Prosecutors have searched Volkswagen's Wolfsburg, Germany, headquarters, as well as Audi offices in Ingolstadt and Neckarsulm and even the homes of some Audi executives, Reuters reports. The raids, which coincided with Audi's annual earnings press conference, are related to 80,000 diesel vehicles with possible emissions cheat devices sold in the US between 2009 and 2015. European vehicles aren't part of this particular investigation. "With these search orders, we aim to clarify in particular who was involved in deploying the technology concerned and in the provision of false information to third parties," the Munich prosecutor's office says. Audi CEO Rupert Stadler, who says his residence had not been one of those searched, says he is supporting the ongoing investigation, admitting that the company has a long way to go to recover from the scandal. The Dieselgate scandal, as it has come to be known, broke in September 2015. Related Video:
