New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

Volkswagen Group launches Truck and Bus GmbH

Volkswagen is not only one of the largest automakers in the world – it's also one of the biggest producers of commercial vehicles. Not just vans like the Caddy and Crafter, but proper trucks and buses. And now it's reorganizing them all under the newly incorporated Truck & Bus GmbH. The new division brings VW's two truck manufacturers MAN and Scania under one roof. MAN is, after all, wholly owned by Volkswagen, and in turn holds over 75 percent of the shares in Scania (as well as MAN Latin America). Along with Volkswagen Commercial Vehicles, they make the Volkswagen Group one of the largest truck manufacturers in the world, behind Daimler and Volvo (the truck manufacturer is separate from the automaker). Although VW Commercial Vehicles will apparently not form part of Truck & Bus GmbH (since it makes smaller vans more than trucks and buses), it will also report to Andreas Renschler, the Volkswagen board member in charge of the company's work vehicle operations. Renschler previously served in a similar role at Daimler. In a bit of a reversal – or a sign of things to come – Volkswagen CEO Martin Winterkorn (who just survived a failed overthrow attempt by ousted chairman Ferdinand Piech) will sit as chair of the supervisory board of Truck & Bus GmbH. Wolfsburg, 05 May 2015 Volkswagen creates integrated commercial vehicles group • Truck & Bus GmbH to become holding for commercial vehicle brands • Prof. Martin Winterkorn: "MAN and Scania will together become global champion" • Board Member for Commercial Vehicles Andreas Renschler: "MAN and Scania brands retain their independence" • Works Council Chairman Bernd Osterloh: "The holding strengthens employees' participation rights" Volkswagen is creating the integrated commercial vehicles group and thus putting in place a structured framework for business with mid-sized and heavy trucks and buses. Truck & Bus GmbH is to become the new Volkswagen Group holding for the MAN und Scania commercial vehicle brands. This was decided yesterday (Monday) by the Supervisory Board of Volkswagen AG. To this end, the shares in Scania AB held by Volkswagen AG will be transferred to Truck & Bus GmbH. The wholly-owned Volkswagen subsidiary already holds 75.28 percent of the voting rights in MAN SE. Truck & Bus GmbH will establish processes specific to the commercial vehicles business, thus leveraging the full synergy potential between the brands.

VW execs didn't think diesel problem would be so serious

Volkswagen Group has admitted that former chairman Martin Winterkorn received two memos about the diesel scandal in 2014. Top execs ignored the problem because they didn't think it was a serious issue. VW disclosed these details to counter allegations in a German shareholder lawsuit that alleged the automaker violated the law by withholding the info from investors. A memo on May 23, 2014 first advised Winterkorn about emissions cheating. A memo on May 23, 2014, first advised Winterkorn about the study from the International Council on Clean Transportation, which identified the emissions cheating. According to VW, the document was part of the exec's weekend mail, and the company's investigation didn't discover whether Winterkorn actually read it. A rumor last month alleged this memo existed. Another memo for Winterkorn on November 14, 2014 was about several defects, including the diesel engines. The document estimated it would cost 20 million euros ($22 million US at current rates) to fix the problem. The chairman learned about the issue again on July 27, 2015, during a meeting on product issues. "Mr. Winterkorn asked for further clarification of the issue," according to VW's statement. Things got serious at the end of August 2015. Things got serious at the end of August 2015 when technicians explained the diesel issue to the legal department. VW came clean to the California Air Resources Board and the Environmental Protection Agency on September 3. A memo told Winterkorn the next day, which was also previously alleged. According to this investigation, management didn't believe the diesel problem would affect the stock price, and they estimated the cheating might cost at most a few hundred million dollars in fines. The execs were clearly wrong. The share price dropped after the scandal broke last September, and the problems have started to affect its divisions. According to Reuters, Audi reported it suffered 228 million euros ($249 million) in costs in 2015 from the emissions issue and repairing Takata's faulty airbag inflators. Volkswagen still doesn't know the exact costs of the scandal, but the automaker's law firm, Jones Day, plans to release a report in the second half of April to explain the whole affair. By that time, we might also know how VW plans to fix the problem because a judge recently gave the company until March 24 to outline a fix for the 2.0-liter TDI. CARB started evaluating a repair plan for the 3.0-liter TDI in early February.
