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:

The super-sized Atlas isn't the three-row VW should build

In the late '50s and early '60s the Volkswagen Beetle wasn't ubiquitous in my hometown of Lincoln, Nebraska, but it came pretty damn close. Fords and Chevys dominated, but beyond the occasional MG, Triumph, or Renault the import scene was essentially a VW scene. When my folks finally pulled the trigger on a second car they bought a Beetle, and that shopping process was my first exposure to a Volkswagen showroom. For our family VW love wasn't a cult, but our '66 model spoke – as did all Volkswagens and most imports at the time – of a return to common sense in your transportation choice. As VW's own marketing so wonderfully communicated, you didn't need big fins or annual model changes to go grab that carton of milk. Or, for that matter, to grab a week's worth of family holiday. In the wretched excess that was most of Motown at the time, the Beetle, Combi, Squareback, and even Karmann Ghia spoke to a minimal – but never plain – take on transportation as personal expression. Fifty years after that initial Beetle exposure, and as a fan of imports for what I believe to be all of the right reasons, the introduction of Volkswagen's Atlas to the world market is akin to a sociological gut punch. How is it that a brand whose modus operandi was to be the anti-Detroit could find itself warmly embracing Detroit and the excess it has historically embodied? Don't tell me it's because VW's Americanization of the Passat is going so well. To be fair, the domestic do-over of import brands didn't begin with the new Atlas crossover. Imports have been growing fat almost as long as Americans have, and it's a global trend. An early 911 is a veritable wisp when compared to its current counterpart, which constitutes – coincidentally – a 50-year gestation. In comparing today's BMW 3 Series to its' '77 predecessor, I see a 5 Series footprint. And how did four adults go to lunch in the early 3 Series? It is so much smaller than what we've become accustomed to today; the current 2 Series is more substantial. My empty-nester-view of three-row crossovers is true for most shoppers: If you need three rows of passenger capacity no more than two or three times a year – and most don't – rent it forgawdsake. If you do need the space more often, consider a minivan, which goes about its three-row mission with far more utility (and humility) than any SUV.
