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.

California orders VW Group to fix 15,000 3.0L diesel vehicles

The California Air Resources Board has ordered Volkswagen to come up with a plan for repairing approximately 15,000 cars sold in the state that contain illegal software that may circumvent emissions testing. In a letter sent to Volkswagen Group of America and several company brands, CARB's chief emissions officer says the company has 45 business days to submit a recall plan that will fix affected Volkswagen, Audi, and Porsche models equipped with 3.0-liter diesel engines sold in the state since 2009. "We expect full cooperation in this investigation so this issue can be addressed expeditiously and appropriately," wrote Annette Herbert, chief of emissions compliance. The violations first surfaced in a meeting last week between California regulatory officials and Audi executives. In that meeting, Audi admitted certain versions of A6, A7, A8, Q5 and Q7 models contained three previously undisclosed auxiliary emissions control devices. An auxiliary device is not necessarily the same as a defeat device that intentionally cheats on emissions testing, but Audi and other affected brands hadn't disclosed the existence of the AECDs, which is a violation of the state's health and safety code. Had they been disclosed prior to vehicle certification, there's a possibility CARB may have approved use of the devices. In a statement Wednesday, CARB did not elaborate on whether it considered the three devices mere AECDs or defeat devices. When Volkswagen submits its plan to fix the cars, CARB says it must include an assessment of how the repairs will affect fuel economy, performance, drivability, and the safety of each vehicle. The 15,000 cars affected in California are part of roughly 85,000 nationwide which contain the affected 3.0-liter engines. The US Environmental Protection Agency may soon address how it expects Volkswagen to fix the remaining cars. "EPA and CARB are working closely and continue to investigate following the admission by Volkswagen that the issues EPA identified in the November 2nd NOV (Notice of Violations) extend to all 3.0-liter diesel Volkswagen, Audi, and Porsche vehicles," an agency spokesperson said in a statement Wednesday. "EPA will take all appropriate enforcement action." The 3.0-liter developments, of course, come on top of the company's September admission that 482,000 diesels equipped with 2.0-liter engines contain defeat devices that detect emissions testing and alter the cars' performance.
