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

German automakers' stocks fall as EU investigates collusion

BERLIN/FRANKFURT - Volkswagen will hold a special supervisory board meeting on Wednesday to discuss allegations that German carmakers operated a wide-ranging cartel, a source familiar with the matter said on Monday. The European Commission said on Saturday antitrust regulators were investigating a possible German auto industry cartel following a tipoff. At stake is whether carmakers VW, Audi, Porsche, Mercedes and BMW used German auto industry committees to discuss pricing of components and technologies, and whether such talks constituted anti-competitive behavior. A VW spokesman confirmed an extraordinary supervisory board meeting would be held on Wednesday but declined to give details. German auto stocks took a hit in early trading on Monday, weighed down by uncertainty over possible antitrust fines after European regulators said they were probing cartel allegations. VW shares were down 2.8 percent, with Daimler and BMW down 3.4 percent and 2.5 percent respectively, lagging the blue-chip DAX index, which was 0.7 percent lower. Exane BNP Paribas automotive analyst Stuart Pearson said little was known about the allegations, but no signs had emerged about fixing prices charged to consumers. "More ugly details could yet emerge, leaving German manufacturers - and the EU auto sector - still firmly in the sin bin for now," he added. The car industry has been hit with billion-euro fines on both sides of the Atlantic in recent years for cartels related to various parts such as lighting systems, engine coolers and bearings. The industry's record on exhaust emissions is also under close scrutiny after VW admitted in September 2015 to cheating U.S. diesel emissions tests and investigations have shown many vehicles exceeding pollution limits outside of testing labs. On Friday, German magazine Der Spiegel said VW, its Audi and Porsche brands, Mercedes-owner Daimler and BMW may have colluded to fix prices on components, including of diesel emissions treatment systems, using industry committees. Spiegel said the talks also led to the use of smaller tanks containing AdBlue, a urea-based liquid needed to help filter nitrogen oxides (NOx) from diesel emissions. Larger tanks would have been more expensive, the magazine said. Auto industry experts, however, have said the effectiveness of exhaust filtering systems does not depend on the size of an AdBlue Tank. BMW, for example, has equipped its cars with urea injection as well as a NOx-storage catalytic converter.
