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:

2014 Audi R8 V10 Plus

Ignore the naysayers who say the Audi R8 is too refined to be a proper supercar, or that it has begun to show its age - after a few tweaks for the 2014 model year, the automaker's flagship remains one of my favorite exotics.
Audi has treated all of its R8 models to a host of enhancements for the 2014 model year that include new LED headlights and tail lamps, larger steering wheel-mounted shift paddles, new exhaust finishes, updated alloy wheel designs and fresh exterior colors. However, the most significant news is the arrival of a proper seven-speed S-Tronic dual-clutch automatic transmission (it replaces the six-speed R-Tronic). The rapid-fire gearbox shaves a coupe tenths off the 0-60 sprint and improves fuel economy for both the eight- and ten-cylinder models (thankfully, a traditional six-speed manual is still on the order form).
I recently spent time with the new-for-2014 V10 Plus model, which is only available in a coupe body style. Compared to the standard V10 models, the Plus sheds upwards of 130 pounds thanks to lightweight manual seats (not fitted to my test car), carbon-ceramic brakes, reduced sound bay insulation, a smaller fuel tank and an assortment of carbon-fiber pieces (including side blades, front splitter, rear diffuser and spoiler). But that's not all, as the V10 Plus also receives a bump in output that pushes its ten-cylinder to an even 550 horsepower.

Junkyard Gem: 1987 Audi 5000

The third-generation Audi 100 introduced for the 1983 model year was sold as the Audi 5000 in the United States. Sales of this high-end German sedan went pretty well ... until 60 Minutes ran a piece called "Out of Control" in late 1986, convincing many viewers that the 5000 was murderously defective. Yes, it was the original Unintended Acceleration debacle, decades before the one that cost Toyota big yen, and it slaughtered American Audi sales. Today's Junkyard Gem had the misfortune to be sitting in an Audi showroom while the echoes of the argle-bargle over the 5000 controversy still reverberated, its price dropping while potential buyers headed into the arms of nearby Mercedes-Benz and BMW dealers. Still, someone bought this car, which would have been a great Colorado winter machine with its 5-speed and Quattro all-wheel-drive system, and it ended up racking up more miles than 98 percent of cars sold in 1987. The presence of an ignition key in a junkyard car usually indicates that it was a trade-in or insurance total. A high-mile, 29-year-old Audi isn't worth much at auction, so this one ended up here. All the automatic-equipped 5000s got scary warning stickers on the shifters, among other recall-mandated changes, and Audi ended up using the European-market 100 name on these cars starting in the 1989 model year .
