VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.

VW recalls 25k Jettas over low-beam headlight issue

Volkswagen has discovered an issue with the headlamps on its latest Jetta and is issuing a recall notice in conjunction with the National Highway Traffic Safety Administration to correct the issue. The problem revolves around the headlight control module, which has been found in certain instances to switch off the low-beam headlights when the high beams are turned on. Needless to say, that could result in insufficient illumination in the dark, so VW is moving to update the module's software. The issue only affects the new 2015 Jetta – specifically those manufactured between July 11, 2014 (which just happens to be this writer's birthday, thank you very much) and November 13, 2014. All in all, the Volkswagen Group of America estimates that encompasses 25,007 units in the United States, the owners of which can expect to hear from their dealers in the new year. RECALL Subject : Insufficient Headlight Output Report Receipt Date: DEC 15, 2014 NHTSA Campaign Number: 14V790000 Component(s): EXTERIOR LIGHTING Potential Number of Units Affected: 25,007 All Products Associated with this Recall close VOLKSWAGEN JETTA 2015 Manufacturer: Volkswagen Group of America, Inc. SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2015 Jetta vehicles manufactured July 11, 2014, to November 13, 2014. Due to incorrect software within the headlight control module, the low beam headlights may turn off when high beam lights are turned on. As a result, the light output from the headlights may be insufficient. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108. "Lamps, Reflective Devices, and Associated Equipment." CONSEQUENCE: Insufficient headlight output may increase the risk of a crash. REMEDY: Volkswagen will notify owners, and dealers will update the headlight control module software, free of charge. The recall is expected to begin in January 2015. Owners may contact Volkswagen customer service at 1-800-893-5298. Volkswagen's number for this recall is 57F6. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

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.
