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:

VW Golf GTI wrung out by Chris Harris

Enthusiasts like nothing more than to crucify modern interpretations of their favorite performance models for failing to live up to some imagined ethos. Even the Volkswagen GTI has suffered its fair share of slings and arrows for growing in size and curb weight. Chris Harris recently spent some time with the all-new MK VII GTI to find out if growing up means giving up on what makes the machine so special.
Judging by his comments, Harris certainly doesn't think so. Yes, the new GTI is considerably more comfortable than its predecessors, but that's hardly a bad thing. The multitude of driving modes actually seem to add depth to the car rather than simply try to force one tool to do many jobs, and Harris even finds the machine's electronic power steering tolerable. As a result, Harris goes so far as to call the Volkswagen GTI "one of the best cars to actually own." How's that for high praise? You can watch the video for yourself by scrolling below.

Volkswagen Diesels: Buy, sell, or hold?

Everyone who owns or has remotely considered a Volkswagen diesel over the past 45 days has tried to figure out the right formula. Is it worth buying after the recall? If I own one, should I sell it? How will it perform if I want to keep it? Questions create doubts, and doubts create a stunning lack of activity when it comes to the new and used car market. I seriously doubt Volkswagen will be rolling out its 2016 TDI models anytime soon. The company already failed to create a fix nearly a year ago and has spent an unusually long amount of time trying to get the formula right. There's also the fact that it rescinded its EPA application for 2016 models. I can't provide the ultimate oracle's guide on whether any recalled Volkswagen diesel will fall under the "good value" perceptions of car buyers. But I do believe four factors in particular will be largely independent of the outcome of that recall, and they're what you should pay particular attention to if you plan on buying any Volkswagen diesel – new or used. 1. Demand Creating Bad Supply There are a large number of car buyers who believe that they can zig while the marketplace tells them to zag. Unfortunately, those are the ones that get sent to the slaughter once articles like the one linked above proclaim, "resale values are down 13 percent." These heavily biased write-ups ignore the fact both the supply and demand of new and used recalled Volkswagen diesels are no longer operating in that free market. The supply side is obvious since the EPA has put a stop-sale on all Volkswagen diesels. However, on the demand side, those Volkswagen dealers who have exclusive access to off-lease vehicles and certified pre-owned programs for 2012 and newer VW diesels are now sitting on the sidelines with all those cars. When your best players no longer play, consumers don't come to the ballpark. What exists right now is a lot like a professional sports strike where the talent sits out until a collective agreement is reached. When your best players no longer play, consumers don't come to the ballpark. The marketplace only offers scabs that can play an inferior game. In the wholesale car business, the scabs are salvage vehicles that are wrecked or flood damaged, vehicles that can't be put under a CPO program due to frame damage and lemon law requirements, and the wholesale repossession market. All of these substandard vehicles make up the new supply, the collective underbelly of low-end quality in the used car marketplace.
