Volkswagen has submitted plans for fixing its cheating diesel engines

Volkswagen had then disputed the software was able to defeat emissions tests.Volkswagen on Thursday told government officials the disputed software is on all 2009-2016 three-liter diesel models, regulators said.

While the alternative exhaust control device fitted to the 3.0-liter TDI violates US law, Audi – whose ad slogan is, ironically, “This is Truth in Engineering” – points out that it’s legal in Europe but executives failed to properly notify regulators of its existence.

Surprisingly, only a small minority (22%) of diesel vehicle owners have concerns that their cars will be harder to sell second-hand; more than half (51%) have no such fears with a further quarter (27%) uncertain whether it will or won’t affect re-sale. Volkswagen presented California regulators on Friday with a proposal to make its 2.0-liter diesel engines compliant with pollution standards for smog-causing nitrogen oxides.

Clearly, VW are going to have another mess to clear up in the United States with the 3.0 litre diesel engines, but it’s unacceptable – if it proves to be the case – that they will escape any kind of sanction in Europe because the regulations are so flawed that the actual emissions of NOx are not subject to limits.

Meantime, a new mass air flow sensor worth about €10 could finally be enough to bring Volkswagen’s 1.6-litre diesel engines into line with EU5 emissions rules.

Volkswagen is committed to fixing its tainted vehicle lines, saying in a statement Monday that they would continue to fully cooperate with authorities to uncover the extent of their emission deception.

The engines in question were built by Audi and distributed to Porsche and Volkswagen as well, said David Clegern, a California Air Resources Board spokesman.

VW made the disclosure on Thursday, a day before it submitted plans to the EPA to fix a much larger problem – emissions-cheating software on 482,000 four-cylinder diesel cars.

Volkswagen will reduce spending by 1 billion euros ($1.07 billion) in 2016 and “strictly prioritize” investments as it readies to contend with the ongoing fallout from the scandal, CEO Michael Mueller said in a statement Friday.

Audi said the focus “will be on finding quick, uncomplicated and customer-friendly solutions”. Those engines found their way under the hood of the A6, A7, A8, A8L, and Q5 TDI models. A fix for 1.2-liter engines affected by the emissions cheating scandal is still being readied.

Volkswagen (Other OTC: VLKAF – news) has subsequently revealed that it had also understated carbon dioxide emissions of 800,000 vehicles, including petrol cars.
