Report: U.S. Finds Unapproved Software on VW 3.0L TDI V-6

System Allegedly Disables Emissions Controls After First 20 Minutes

Aug 8, 2016
Just when it seemed it couldn’t get any worse for Volkswagen, German newspaper Bild am Sonntag via Reuters has reported that U.S. regulators have found additional unapproved software on the company’s 3.0L TDI V-6 models that reportedly disable emissions controls after the first 22 minutes of operation. Most standard emissions tests last approximately 20 minutes. The engine is offered in the VW Touareg, Audi Q7 and Q5 SUVs, and the Porsche Cayenne. There were reportedly plans to also offer it in the Porsche Macan prior to the scandal.
Representatives from VW and Audi are reportedly scheduled to appear at a hearing before U.S. regulators on August 10 to answer questions. VW has already said it would commit up to $15.3 billion to deal with the settlement for the 2.0L TDI models, which includes a technical fix, as well as buyback offers. A final settlement covering the estimated 85,000 3.0L TDI models is expected within a few months. All of those models are equipped with a urea fluid selective reduction catalyst (SCR) system to control NOx emissions, and it’s believed a fix to bring them into compliance will be easier than for the 2.0L TDI models equipped with a so-called “NOx Trap” that do not have a fluid SCR system.
