VW recalling 2.64M vehicles worldwide over engine, light issues

Volkswagen is staging a massive, worldwide recall that's already grown from 1.68 million to 2.64 million vehicles and covers three different issues across a number of vehicles. We already reported on 61,000 Tiguans getting recalled over lighting issues - that was just in the US. Globally, however, VW will be recalling 800,000 Tiguans, according to Automotive News, with the focus on CUVs built between 2008 and 2011. The issue with the Tiguan relates to a simple fuse swap, so this is rather unremarkable, aside from the sheer number of vehicles being fixed. The real, troubling issues relate to gearboxes and pickups.
239,000 Amarok pickups (pictured right) are being recalled over fuel leaks, while 1.6 million vehicles are being recalled to swap the synthetic oil in dual-clutch transmissions with mineral oil. Now, the transmission issue is one for the global Volkswagen Group to address, not just the VW brand - vehicles from Audi, Škoda and Seat use the same seven-speed DSG and are covered under the recall, as well.
Why the switch from synthetic to mineral oil? Apparently, using the synthetic oil in a DSG and then subjecting it to stop-and-go conditions or heavy loads in a hot and humid climate can lead to electronic malfunctions, according to a Volkswagen press release. The switch, from the sounds of it, is largely a preventative measure.

Audi rumored to buy Alfa Romeo, officials deny it

For more than two years, Volkswagen has been making public statements about its willingness to buy Alfa Romeo and quadruple the Italian brand's sales, and for just as long, Fiat CEO Sergio Marchionne has replied with some version of "Mr. Piëch, drop it." According to a report in Ward's Auto, all that jousting might be over: it claims that sources close to both Marchionne and Audi CEO Rupert Stadler admit that the two are in talks for Audi to buy not just Alfa Romeo, but a production plant in Italy. In fact, a final deal could possibly include partsmaker Magnetti Marelli.
Against that backdrop, a report by German news weekly Stern quotes a Fiat spokesmen as saying it doesn't comment on rumors and an Audi rep has said flatly that "There is no substance in the news." If a sale is being arranged, the timing would seem to point to how eager Fiat is to raise cash to complete its major initiatives. Even though Alfa Romeo continues to delay its return to the US, it just showed off the production version of the 4C at the Geneva Motor Show (shown above) and said that preferred Fiat dealerships here would get them. Then there's Alfa's recently concluded deal with Mazda to develop a roadster based on the next generation MX-5 Miata - a deal that would seem to help both the Italian and Japanese brands.
The monetary issues are troublesome, though. Fiat is taking a beating in the European market and its weak-kneed balance sheet is delaying gotta-have-it products like the Jeep Cherokee. Fiat has been talking to banks about getting money to buy the rest of Chrysler and those financial institutions have also raised issues about debt and cash reserves, and the nasty game of chess Fiat is playing with the United Auto Workers (and now the court system about the portion of Chrysler it doesn't own) could end up blowing another hole in Marchionne's plans. It is possible that this could finally have convinced Fiat to at least see how serious Audi's parent company, Volkswagen, is about buying Alfa Romeo. Or it could be just another rumor.

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.
