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:

Audi S1 nearly ready to rocket euros out of your pocket

Audi was out testing its upcoming S1 on the streets of Germany when our trusty spy photographers snapped the new, all-wheel-drive hot hatch that's set to succeed the limited-edition A1 Quattro.
Unlike the A1 Quattro, the S1 should sport a much less aggressive look overall. As shown in the spy shots, its wheel wells lack the meaty flairs of its predecessor while its rear wing is much more subdued. The wheels are more in line with what we expect from Audi's S models and its higher ride height is more conducive to common things like steep driveways and speed bumps that the 333-unit A1 Quattro might not encounter.
According to our spies, the S1 should hit the European market with anywhere from 220 to 250 horsepower, making it considerably more potent than competitors like the Ford Fiesta ST or Polo GTI from its parent company, Volkswagen (although it'll likely arrive at a considerably higher price than either of those pocket rockets). On the high end, that's roughly equal to the 252 ponies generated by the 2.0-liter, turbocharged four in the A1 Quattro

Audi mechanic takes owner's S4 home for the weekend

When you bring your car to a dealer, you expect a technician to take it out for a spin, just to make sure there aren't any noises, rattles or other behavior that you may have missed. Maybe they run a few miles along a predetermined test route or take a quick run down the highway. You do not, however, expect a tech to abscond with you vehicle for a full weekend
That is just what happened to Chris Jackson, though, an Audi S4 owner in Calgary. His car was taken to Glenmore Audi - as mandated in his lease agreement - due to an issue with the navigation system. After realizing he'd left something in the car, he swung by the dealer on Saturday to pick it up, only to discover the car wasn't on the dealer's lot.
Naturally, he approached the dealer about the missing sedan.
