To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Volkswagen Group recalls 281,505 VWs and Audis for fuel leaks

The Basics: Volkswagen Group is recalling 281,505 total Volkswagen and Audi brand products in the United States for potential fuel leaks. Certain versions of the Audi A3, A6, A7, Q5, and Q7 are affected. In addition, some versions of the Volkswagen Golf, Golf SportWagen, and Golf GTI fall under the recall. It's unclear if vehicles outside of the United States will be recalled as well. The Problem: There are actually three separate recalls for three separate issues that all pertain to leaky fuel. All three recalls were issued simultaneously. The risk of unintended ignition is the main concern here. First off, 2012-2013 Audi A6 and Audi A7 models [28,249 cars] are being recalled because of a degrading fuel hose in the engine compartment. Secondly, 143,214 gas-powered 2009-2012 Audi Q5s and 2007-2012 Audi Q7s are being recalled. The fuel cap may crack on these vehicles, leaking fuel. Finally, 110,042 total units of the 2015-2016 Volkswagen Golf, Golf SportWagen, GTI, Audi A3 sedan, and A3 Cabriolet will be recalled because of fuel leaking from the evaporative emissions system. Injuries/Deaths: According to Reuters, Volkswagen has reported no injuries or deaths related to the fuel leaks. In addition, the company has said there have been no fires started due to the leaks. The Fix: Three separate issues means three separate fixes. Volkswagen and Audi will be reaching out to customers soon, though the parts aren't yet available. For the A6 and A7, Audi will simply replace the under hood hose. For the Q5 and Q7, dealers will clean the pump flange and install a butyl rubber band to protect the pump. Finally, the affected Golf and A3 models will have the suction cup in the emissions system replaced. If you own one: Volkswagen and Audi will begin contacting owners starting next month regarding a fix. Related Video: News Source: NHTSA, Reuters Recalls Audi Volkswagen

Munich prosecutors arrest Audi employee in emissions probe

Munich prosecutors arrested an Audi employee on suspicion of fraud and false advertising in connection with the carmaker's emissions scandal, the first arrest in Germany related to Volkswagen's diesel scandal. The Audi employee was arrested on Monday, at the behest of Munich prosecutors, a spokeswoman for the Munich prosecutors office said on Friday. When asked if the arrest was at the request of US authorities, the spokeswoman said it was not. She did not give the name of the person. Munich prosecutors declined to comment on whether the arrested person is a current or former Audi employee. Audi and parent Volkswagen both declined to comment. On Thursday, the US Justice Department said it charged former manager Giovanni Pamio with directing Audi employees to design software to cheat US emissions tests in thousands of Audi diesel cars. Audi is a division of Volkswagen Group. The Munich prosecutor's office said the Audi employee was brought before a judge on Tuesday and was now being held in custody. The spokeswoman declined to discuss the possibility of the detained person being extradited to another country or comment on whether Munich prosecutors were in touch with US authorities. The German arrest was part of a wider probe into fraud and false advertising and is a consequence of "findings following searches," the spokeswoman said. In March, Munich prosecutors searched the offices of Jones Day, the lawfirm Volkswagen had hired to lead an internal investigation into its emissions scandal and Audi's headquarters. Volkswagen condemned the searches at the time, and never published the full findings of its internal investigation which was being conducted by Jones Day. The raids by Munich prosecutors in March sought to shed light on who was involved in the designing and using illicit software used in 80,000 VW, Audi and Porsche cars with bigger 3.0-liter engines. No members of the Audi management board are being personally investigated as part of that probe, the spokeswoman said on Friday. In the criminal complaint released by US authorities on Thursday, US prosecutors charged that Pamio ignored or suppressed warnings by certain Audi engineers that the pollution control systems being used on the brand's diesel engines violated US clean air rules. US prosecutors said Pamio had ordered subordinates to send false information to American regulators stating that Audi's "clean diesels" did not use technology designed to cheat federal pollution tests.
