There might be a second VW software cheat

The initial flurry of news about Volkswagen's diesel scandal is just beginning to settle down, but the company is months away from actually having any of the affected vehicles fixed. A stop sale is still in effect on new examples in the US, as well. The remedy process now faces yet another hurdle because the Environmental Protection Agency is requesting more info about other previously undisclosed emissions software on the engines, Bloomberg reports. Separate from the defeat device that evades tests, this new bit of code reportedly helps warm up the engine. However, automakers are supposed to disclose to the EPA any software that can affect emissions. The tech isn't necessarily against the law, but the regulatory agency needs to know about it during evaluations. The company didn't reveal this system until applying for certification on the latest TDIs. "VW did very recently provide EPA with very preliminary information on an auxiliary emissions control device that VW said was included in one or more model years," EPA spokesperson Nick Conger told Bloomberg. In response to the disclosure, VW took back its application for the diesels until it provided more details to the EPA on the previously undisclosed code. So far, there's no evidence that this code is actually another defeat device, though. Regulators are preparing an onslaught of tests on the revised engine to make sure the German automaker isn't gaming the system again. VW has until November 20 to outline a fix for the diesels to the California Air Resources Board. In response to the scandal, the company is preparing for severe cutbacks to have enough money to pay for all of the expected fines and repairs. It also recently announced plans for a serious electrification push in the near future.

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:

Porsche-Piech buy 10% stake in VW's holding company

In August, 2009, as the scuttled merger of Porsche and Volkswagen had gone bad and Porsche was backed up against the ropes, Porsche Automobil Holding SE (PAHSE) relinquished a ten-percent stake in itself to Qatar Holdings as well as options it held on 17 percent of VW shares. The sale meant that, for the first time since the founding of the company 61 years before, an entity outside the Porsche and Piech families had a say in the running of PAHSE.
Buying that ten-percent stake back returns full ownership to the two families, the holding company's sole possession being ownership of 50.7 percent of VW's common shares. The price paid wasn't disclosed, but at market rates the purchase would be worth close to $1.25 billion. Qatar intends to hold onto the 17-percent stake it has in Volkswagen.
