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:

Porsche acquires ANDIAL, will integrate with in-house motorsports

Porsche has purchased longtime motorsports and tuning house ANDIAL.
The Fountain Valley, California-based tuning house ANDIAL has been around since 1975, when it was formed by the Arnold Wagner, Dieter Inzenhofer and Alwin Springer (the company got its name by combining two letters from each of their names). The three men met while working in a Porsche dealership in Southern California and then left to start a business that would put Porsches in victory lane all over the country.
Porsches prepared by ANDIAL won IMSA GT and Supercar Series championships, the SCCA World Challenge, four Pikes Peak class titles and the 24 Hours of Daytona six times. Alwin Springer left the company in 1997 to run Porsche Motorsport North America until 2004 and remains a consultant with PMNA, Wagner passed away in 2011 and Inzenhofer plans to retire this year. ANDIAL is still a going concern, Inzenhofer presiding over a scaled-down engine parts and restoration business. But Inzenhofer is retiring at month's end, making it a good time for Porsche to step in and take over the company's operations.
