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.

Jay Leno listens to the people, shows off still-stock 1972 Mercedes 300 SEL 6.3

Let it be known, Jay Leno is a man of the people. Long-time viewers will recall the time he walked fans of his popular video series around the various projects going on in his eponymous garage. One such vehicle was his 1972 Mercedes-Benz 300 SEL 6.3, which he'd planned on fitting with the powertrain from the awesome SLS AMG. But rather than just make the move and be done with it, Leno asked viewers whether he should restore the silver sedan or carry on with his plan to resto-mod. Well, the restoration team won, and the 6.3-liter sports sedan soldiers on unmolested. That is, of course, no bad thing, according to Leno. In his latest video, he revisits the 1972 luxury sedan, and takes it for a spin around Los Angeles. Fans of Mercedes' big-grilled 1970s styling won't want to miss this video.

Mercedes recalling 33k C-Class and CLS-Class models in separate campaigns

Mercedes-Benz is recalling over 33,000 vehicles in the US in separate actions affecting two of its model lines. The larger campaign covers 30,141 examples of the 2015 CLS400 and CLS400 4Matic; 2012-2015 CLS550 and CLS550 4Matic; 2012-2014 CLS63 AMG and 2014-2015 CLS63P AMG. On these vehicles, the LED taillights do not sufficiently illuminate around the sides, and therefore they run afoul of the Federal Motor Vehicle Safety Standard. According to documents posted by the National Highway Traffic Safety Administration (as a PDF, here), "this is due to a software coding issue which leads to the non-activation of a certain LED in both taillamp units." An update of the programming by the dealer fixes the problem. The other recall covers 3,039 units of the 2015 C300 4Matic and C400 4Matic for two possible problems with the fuel delivery module of the fuel tank. First, the locking plate for the part might loosen on some of these vehicles, and that can cause a fuel leak, which is obviously dangerous. Also, the electric wires going into the component might be pinched, which can lead to failure of the fuel pump. Dealers will inspect the models for both issues and will repair any faults they find. Mercedes did not tell NHTSA when owners would receive notification about either of these campaigns when the company submitted the documentation to the agency on March 10. Autoblog reached out to company spokesperson Christian Bokich via email for more information. "We currently expect to be in touch with customers by late March. Customers may continue to drive their vehicles until the recall is performed," he said.
