There might be a second VW software cheat

The initial flurry of news about Volkswagen's diesel scandal is just beginning to settle down, but the company is months away from actually having any of the affected vehicles fixed. A stop sale is still in effect on new examples in the US, as well. The remedy process now faces yet another hurdle because the Environmental Protection Agency is requesting more info about other previously undisclosed emissions software on the engines, Bloomberg reports. Separate from the defeat device that evades tests, this new bit of code reportedly helps warm up the engine. However, automakers are supposed to disclose to the EPA any software that can affect emissions. The tech isn't necessarily against the law, but the regulatory agency needs to know about it during evaluations. The company didn't reveal this system until applying for certification on the latest TDIs. "VW did very recently provide EPA with very preliminary information on an auxiliary emissions control device that VW said was included in one or more model years," EPA spokesperson Nick Conger told Bloomberg. In response to the disclosure, VW took back its application for the diesels until it provided more details to the EPA on the previously undisclosed code. So far, there's no evidence that this code is actually another defeat device, though. Regulators are preparing an onslaught of tests on the revised engine to make sure the German automaker isn't gaming the system again. VW has until November 20 to outline a fix for the diesels to the California Air Resources Board. In response to the scandal, the company is preparing for severe cutbacks to have enough money to pay for all of the expected fines and repairs. It also recently announced plans for a serious electrification push in the near future.

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.

VW developed 4 separate defeat devices over 7 years

Today brings more bad news for Volkswagen as three anonymous insiders, speaking to Reuters, are claiming that the company modified its emissions defeat device to work on at least four engines over the seven years the company has admitted to cheating. If true, the incremental updates to the software cheat could be evidence of a larger group of employees making an ongoing effort to continue their deception without regulators' knowledge. So far, VW's emissions scandal has embroiled some 11 million vehicles using the EA189 and EA288 diesel engines. "VW would have had to reconfigure the software for each generation of engines," an unnamed official close to the US investigation said to Reuters. Recently, Volkswagen asserted that only a few individuals were involved in the cheat, and challenged a report that at least 30 managers knew about the situation. The report in Reuters, if true, would make VW's claims hard to believe. It might also mean even more legal trouble for VW. According to the report, the Justice Department could seek even harsher punishments if it finds out that more top execs knew more about the issue than VW is letting on. Investigators in Europe have also been working out who was involved in the deception. Italian authorities recently searched the Lamborghini headquarters and VW's main office in the country looking for evidence. Meanwhile, German prosecutors collected documents directly from the automaker's headquarters in Wolfsburg, and regulators there mandated a recall in early 2016. Related Video:
