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 There's also the fact that it rescinded its EPA application for 2016 models.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.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

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:
