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:

Automakers suspend some business in Russia following invasion

(Getty Images)   Global auto and truck makers, including Sweden's Volvo Cars and Germany's Daimler Truck, on Monday suspended some business in Russia following that country's invasion of Ukraine. Russian forces invaded Ukraine last week, marking the biggest attack by one state against another in Europe since World War II. Many firms have idled operations in Russia following Western sanctions against Russia. Energy giant BP Plc, Russia's biggest foreign investor, abruptly announced over the weekend it was abandoning its 20% stake in state-controlled Rosneft at a cost of up to $25 billion. On Monday, Swedish automaker Volvo Cars said it would suspend car shipments to the Russian market until further notice, becoming the first international automaker to do so as sanctions over the invasion continue to bite. In a statement, the company said it had made the decision because of "potential risks associated with trading material with Russia, including the sanctions imposed by the EU and US." "Volvo Cars will not deliver any cars to the Russian market until further notice," it said. A Volvo spokesman said the carmaker exports vehicles to Russia from plants in Sweden, China and the United States. This came as Russia warned Sweden and Finland not to join NATO or risk facing “serious military-political consequences." Volvo sold around 9,000 cars in Russia in 2021, based on industry data. Earlier on Monday, RIA news agency reported Volkswagen had temporarily suspended deliveries of cars already in Russia to local dealerships, citing a company statement. VW had no immediate comment when contacted by Reuters. VW previously said it would halt production for a few days this week at two German factories after a delay in getting parts made in Ukraine. Daimler Truck said on Monday it would freeze its business activities in Russia with immediate effect, including its cooperation with Russian truck maker Kamaz. Mercedes-Benz Group is also looking into legal options to divest its 15% stake in Kamaz as quickly as possible, the Handelsblatt newspaper reported. A Mercedes spokesperson told Reuters business activities would have to be re-evaluated in light of the current events. Mercedes-Benz Group, formerly Daimler AG, was the parent company of Daimler Truck before the truck maker was spun off.

Suspended VW exec Hackenberg resigns in wake of scandal

Ulrich Hackenberg, father of the innovative modular architecture that underpins many modern Volkswagen and Audi products and a 30 year veteran of the giant company, has resigned his position as the lead engineer for the entire Volkswagen Group as well as his seat on Audi's management board, reports Automotive News. The resignation closes out a two-month suspension while the investigation into VW's deceptive emissions practices continues.The resignation follows the admission by Audi that the 3.0-liter TDI V6 engine was also fitted with emissions-control defeating software, like some of its four-cylinder TDI counterparts. In turn, this lead to changes in Audi's management structure. AN reports that Matthias Muller, who has already taken over Martin Winterkorn's position as VW Group CEO, will also be named chairman of the Audi brand.Hackenberg's successor was named as part of this announcement. Stephan Knirsch, who has lead engine development at the Audi division, will assume Hackenberg's roles as both board member for Audi in charge of technical development, and as the head for technical development across the whole group.Related Video:
