BREAKING: Audi Admits to Defeat Device, Details Fix For 3-liter Diesel Engines

Audi, a brand within Volkswagen Group that markets the majority of 3-liter diesel engines sold by the group in the United States, released a statement Monday detailing how it plans to fix vehicles that use a defeat device. The automaker also stated that three separate Auxiliary Emissions Control Devices — not just one — are used in 2009 and later 3-liter diesels used by Audi, Volkswagen (Touareg) and Porsche (Cayenne).

AECDs for those engines will “be revised, documented and submitted for approval,” Audi said in the statement.

Of the three AECDs, the EPA questioned the legality of a temperature conditioning procedure of the exhaust-gas cleaning system.

“One of (the AECDs) is regarded as a defeat device according to applicable US law. Specifically, this is the software for the temperature conditioning of the exhaust-gas cleaning system,” Audi said in a statement.

Volkswagen's Withdrawal of EPA Application Is Not Because of 'Defeat Device' (Update)

Update: Official statement from EPA.

During his voluntary testimony for a congressional committee Thursday, Volkswagen of America CEO Michael Horn announced the company would withdraw their application for emissions certification for 2016 model year Volkswagens powered by 2-liter diesel engines.

However, the reason for that withdrawal is not directly related to the “defeat device” that’s been at the center of the ongoing diesel controversy.

  • Ronnie Schreiber From where is all that electricity needed to power an EV transportation system going to come? Ironically, the only EV evangelist that I know of who even mentions the fragile nature of our electrical grid is Elon Musk. None of the politicians pushing EVs go anywhere near it, well, unless they are advocating for unreliable renewables like wind and solar.
  • FreedMike I just don’t see the market here - I think about 1.2% of Jeep drivers are going to be sold on the fuel cost savings here. And the fuel cost savings are pretty minimal, per the EPA: https://www.fueleconomy.gov/feg/PowerSearch.do?action=noform&path=1&year1=2022&year2=2022&make=Jeep&baseModel=Wrangler&srchtyp=ymm&pageno=1&rowLimit=50Annual fuel costs for this vehicle are $2200 and $2750 for the equivalent base turbo-four model. I don’t get it.
  • FreedMike How about the “Aztek” package? Wait, this car already has that…Said it before and I’ll say it again: they need to restyle the hind end on this car, stat.
  • Johnster "Vale" is the [s]cheap[/s] lower-priced performance version with black trim and stiff suspension."Mist" is the "DeLuxe" version with a bit more chrome and trim. (Sort of like the "Decor Package" option.)"Magentic" is the full-on Brougham treatment (in its current state) with more chrome trim than the "Mist" and all sorts of gimmicky electronic features inside. (Sadly, it will not include simulated landau irons or a vinyl covered roof, even as an option.)"Aurora" is the Oldsmobile of Cadillacs (sort of like the old Cadillac Calais). No, that's not right. It's the top-of-the-line model, sort of a "Grand Touring" version, with not as much chrome as the "Magentic" but all of the gimmicky electronic features and a stiffer suspension.
