VW fix would have cost $335 per vehicle

Since the Volkswagen diesel kerfuffle began, Bosch, the world's largest auto supplier, has been hooked up to a bullhorn trying to make sure everyone knows its side of the story. Bosch supplied VW with the engine management testing software, including delivery and metering modules, that VW then used to skirt emissions laws in the US. Bosch told VW in 2007 that it was illegal to use the software in cars it planned to sell yet VW did it anyway, according to reports coming out in German newspapers Bild am Sonntag and Frankfurter Allgemeine Zeitung. That first warning came two years after VW started developing the small-displacement diesel, around the time that the two men pushing its development, then-brand chief Wolfgang Bernhard and engineer Rudolf Krebs, were telling their superiors that the engine needed AdBlue urea injection to pass US emissions. VW cost controllers wouldn't approve the AdBlue solution because it would add 300 euros ($335 US) to the cost of the vehicle. Bernhard and Krebs left the same year that Bosch advised VW about the software, two years before the engine went into production. That's when things get cloudy. A report in Automotive News says that when Martin Winterkorn took over in 2007 as head of the VW Group and brand, he asked Ulrich Hackenberg and Wolfgang Hatz to keep working on the engine, and "[the] engine then ended up in VW Group diesels" with that problematic software still intact. No one has yet pointed any fingers at this latter chain of command, but like a game of Clue, right now they're the professors in the library holding the candlesticks. Warnings didn't only come from the supplier: Frankfurter says VW's initial investigation has found that an engineer issued the same caution to the company in 2011. Neither Bosch nor VW would comment on the reports.

South Korea to file criminal charges against VW exec

South Korea has tossed out Volkswagen's recall plans and is preparing to level criminal charges over its handling of the diesel emissions catastrophe, The Wall Street Journal reports. "Recall plans the company submitted to us earlier this month were insufficient and lacked key information, and thus are unacceptable," the South Korean Ministry of Environment said in a statement obtained by the WSJ. A ministry official hinted at the possibility of criminal charges earlier this month if VW's recall plan wasn't satisfactory, the Yonhap News Agency reports, and now it looks like it will actually follow through. According to the WSJ, South Korea has already ordered VW to recall 125,000 vehicles and slapped the automaker with a $12.3 million fine – one of the many countries to do so – but if it follows through with criminal charges against the company or its employees, it'd be among the earliest to so. Other countries, including the United States, are still exploring the possibility of criminal charges. Charges would likely come against both Audi Volkswagen Korea and its managing director, Johannes Thammer. It's not clear what the actual charge would be, but the WSJ claims Thammer could be facing up to five years in prison and a fine of 30 million won (around $24,700 at today's rates). For its part, VW officials in South Korea maintains that it is "doing its utmost to resolve the emissions issue" and that it plans to "offer further explanation" to authorities regarding its proposal for an emissions and fuel mileage fix in that country.

Audi moves to patent electric Quattro and active-shutter wheels

Audi might have a few tricks up its sleeve for the coming years, with the Brits at Autocar uncovering a pair of patent filings made by the German luxury brand. The first is something we've seen before - wheel flaps - while the second is an evolution of one of Audi's trademark technologies.
We last saw wheel flaps on the Ford Atlas Concept in 2013, but the futuristic fuel-saving tech has so far failed to arrive on a production car. Audi may be seeking to change that, patenting the flaps that open and close automagically based on airflow. They can also open if the brakes get too hot.
The second patent is an evolution of Audi's Quattro all-wheel drive. The new AWD system uses an electrically driven rear axle and wheel sensors to figure out when and at which corner the car might lose traction, and is targeted largely at hybrid offerings, which is a field Audi has only recently dipped its toe into.
