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.

VW to pay $1B in settlement with US government over V6 diesels

Volkswagen and the US government have come to a settlement for the civil claims against the automaker's 3.0-liter, diesel V6s. Over 83,000 V6 TDI-powered models are currently prowling US roads in violation of emissions laws. The settlement allows VW to recall over 75 percent of its cheating V6 diesels – about 63,000 units – and bring them into compliance. These represent newer VW Touaregs, Audi A6, A7, A8, Q5, and Q7s, and Porsche Cayennes built between 2013 and 2016. According to the company, the recall will bring these so-called Generation Two engines up to emissions specs, provided the EPA and CARB okay the modifications. Should the regulators say no to VW's tweaks, the company will buy back or terminate leases with the affected owners. For older V6 TDIs built between 2009 and 2012, Volkswagen will do broadly the same thing, only in reverse. It will lead with buy backs of older Touaregs and Q7s – the only vehicles the company sold with the earlier engines – but could offer fixes if EPA/CARB give the okay. As part of its agreement over the emissions-cheating V6s, Volkswagen will contribute $225 million to the "environmental remediation trust" it established as part of its settlement over cheating 2.0-liter TDIs. VW is also on the hook for $25 million with CARB, bringing the total for the six-cylinder part of its emissions cheating scandal to around $1 billion, Automotive News reports. This initial agreement still needs approval from US District Court Judge Charles Breyer. Related Video:
