VW confirms Audi's emissions test transmission anomalies

Just a week after reports that the California Air Resources Board (CARB) found an emissions cheat in some Audi automatic transmission software programs, parent company Volkswagen has come clean. As reported by Reuters, VW's response to an article by Munich's Sueddeutsche Zeitung stated that the adaptive shift functionality can "lead to incorrect and non-reproducible results." Adaptive shift programs alter the characteristics of a vehicle's transmission to suit different driving styles. Gentle driving will result in earlier shifts and lower engine revs, while hard-charging on the pedals and steering will make the transmission more responsive and hold gears longer. That adaptation can change over time or even on a short-term basis. And it can save fuel. The difference in this case is that is seems that the Audi transmissions were specifically programmed to detect emissions test conditions. As we explained in a previous article, one of those test conditions is keeping the wheel straight. Turning more than 15 degrees shuts the test mode off. According to Reuters, the US government is trying to determine whether this classifies as an emissions cheat device, although VW, Audi, and the EPA have not commented on the record. This latest accusation is separate from the larger VW diesel emissions scandal. Related Video: Image Credit: Getty Editorial Government/Legal Green Audi Volkswagen Emissions vw diesel scandal

An inside look at VW's new California R&D center

Less than two months ago, the Volkswagen Group opened a new facility in Oxnard, California (about an hour's drive west of Los Angeles). The $27 million investment, touted as Test Center California (TCC), serves as a research and development lab testing emissions for all brands under Volkswagen's umbrella, including its newest member, Porsche. While still not fully operational, we toured the new 64,000-square-foot building last week and had a first-hand opportunity to see just how much work is involved testing engines and meeting increasingly stringent government emissions standards.
Replacing a similar facility established in 1990 in Westlake Village (about 20-minutes east of the new location), our guide explained how Oxnard was chosen for its temperate climate, varied regional terrain for test drives and low altitude. (The area is only a few feet above sea level - a critical parameter when instrument testing emissions.) The new facility is capable of analyzing hundreds of vehicles, prototypes and customer-owned vehicles, annually.
Most interesting to us was the huge stainless steel climate chamber, with a massive four-wheel dynamometer that allows VW to test running vehicles in both scorching desert and freezing climates without ever leaving the building (an Audi Q7 was running in place during our visit). We were also mesmerized by the countless storage tanks and intricate plumbing of chemicals, stored in both liquid and gas states, needed to perform the variety of tests. Lastly, we took a look at Bugatti's service center on the west coast, located completely within the new center. While there were no supercars on site, the facility is equipped with plenty of spare forged wheels (mounted with expensive Michelin PAX tires) and a Veyron-specific repair jig that allows the vehicle to be completely disassembled, if needed. It is a shame that the facility, which set off all of our automotive geek alerts, is closed to the public.

Volkswagen pushed back against Takata airbag recall

Volkswagen and Audi will recall about 850,000 vehicles in the US to replace their Takata-supplied driver side airbag inflators, but the automaker doesn't believe the safety campaign is entirely necessary. In a letter to the National Highway Traffic Safety Administration, the company pushes the agency to re-evaluate the recall's scope because the parts are allegedly safe, it claims. VW asserted in the letter, which NHTSA posted online (as a PDF) with other documents about the company's safety campaign, that the vast majority of the automaker's recalled vehicles used Takata inflators from the supplier's factory in Freiburg, Germany. Only the US-built Passat had components from Takata's plant in Mexico. VW's argues to NHTSA that its recall is unnecessary because there are no reported airbag ruptures in the German-made parts, and the plant has better quality control than Takata's factories in the US and Mexico. In addition, the Mexico-manufactured components in the Passat are also allegedly safe because they come from a time after significant upgrades to the plant to address humidity and welding concerns. "We do not believe the facts known to date support the scope as defined in the Takata defect notification," VW's letter says. To be clear, VW is not refusing the Takata recall and plans to fix the affected vehicles. Instead, this letter shows the automaker expressing an opinion that NHTSA's scope for the campaign is too broad. VW now plans to do its own analysis on the inflators to strengthen that case, according to The Detroit News. "We respectfully request that, should such results be shown, the agency work with Volkswagen and other manufacturers to revisit the scope of these recalls," the letter said. Takata's recalled inflators use ammonium nitrate as a propellant, and experts believe that long-term exposure to high humidity can make the chemical more likely to cause a rupture during airbag deployment. The spray of metal shrapnel from the exploding parts has links to at least 10 deaths. Related Video:
