VW secretly added code to their 2009-2015 diesel engine control computer to recognize when emission testing was taking place in order to temporarily comply with clean air regulations. Otherwise, their cars emit 10-40x too much smog-forming nitrogen oxide. They only fessed-up when EPA threatened to block sales of their 2016 cars while the excess emissions were being investigated. The potential fine is $37,500 for each of 482,000 cars sold. EPA accuses Volkswagen, Audi of evading emission laws EPA's Notice of Violation to VW: http://www3.epa.gov/otaq/cert/documents/vw-nov-caa-09-18-15.pdf
Interesting and fascinating. That's a huge and potentially devastating scandal for VW. The other thing I wonder about, is the exclamation from the EPA that VW would be required to "fix" the cars for free. How? If the EPA's desire or contention is to force VW to make the vehicles legitimately produce the emission results they were producing falsely due to the defeat mechanism hidden in their software, I don't see how VW does "fix" the problem. The software evidently was specifically designed to defeat the test, but the vehicles aren't designed to operate in the real world with the same parameters. If I was a VW owner I'd be very upset. My vehicle suddenly doesn't meet the emission standards it was suppose to meet, AND even IF VW can/could make software/hardware adjustments necessary for the vehicle to honestly and legitimately meet those standards would the vehicle then perform in the manner I have come to expect and in the manner it performed when I purchased it? What a mess. VW's new slogan should become " Oh what a tangled web we weave, when first we practice to deceive! '. VW is evidently cooperating with investigation. I'll be interested in how this all plays out as more information is brought to light. Who knew what and when. I suppose I should say, at this point it's allegations and accusations.
With the EPA story just coming out Today... wonder if VW can pull it off still if EPA fines them $18 billion.
Source: http://www.nytimes.com/2015/09/19/business/volkswagen-is-ordered-to-recall-nearly-500000-vehicles-over-emissions-software.html?_r=0 The Environmental Protection Agency issued the company a notice of violation and accused the company of breaking the law by installing software known as a “defeat device” in 4-cylinder Volkswagen and Audi vehicles from model years 2009-15. The device is programmed to detect when the car is undergoing official emissions testing, and to only turn on full emissions control systems during that testing. Those controls are turned off during normal driving situations, when the vehicles pollute far more heavily than reported by the manufacturer, the E.P.A. said. Bob Wilson
The full story is still unraveling but my understanding at the moment is that these cars were sold without the urea-based diesel emissions treatment hardware that other car makers had to use. VW claimed they were able to meet the emissions standard without resorting to using the urea hardware and that gave their cars a cost and maintenance advantage. I'm guessing they will end up retrofitting urea emissions treatment hardware onto those 482,000 cars at far higher cost than if they had just included them in the cars at the factory originally. Plus large fines. Plus many hours and legal fees dealing with regulators and investigations. This was such an egregious scam that they may very well end up in a criminal investigation. GM didn't intentionally ask their supplier to design a bad ignition lock (the lock failed to meet GM's original design specification). GM made design changes along the way to fix it in newer cars but were caught up for not disclosing the original problem to avoid having to recall earlier cars and compensate victims of accidents in earlier cars. Toyota didn't intentionally design inadequately secured carpet mats, accelerator pedal HW, etc. that caused some stuck accelerator pedal events. They were caught up for not disclosing the problems and in some cases lying to regulators about it. Here, VW seems to have intentionally inserted software in their cars to detect emission control testing in order to change the engine controls so as to pass while otherwise operating in a non-compliant mode during normal operation. No individual deaths can be directly traced to the excess NOx emissions but statistically people die from NOx. They seem to have done this for financial gain. They did this intentionally for 6 years and apparently planned to continue doing it in 2016.
Yikes, this may require its own thread, but part of the plug-in push may be that vw has been cheating on emissions tests in the US http://www.nytimes.com/2015/09/19/business/volkswagen-is-ordered-to-recall-nearly-500000-vehicles-over-emissions-software.html Its not hybrid news, but if they were making hybrids they probably wouldin't have tried to cheat.
As I said I think it's a very interesting story. I'll be interested to hear more details, and interested as to how the media, EPA and VW and VW owners react.
This covers one of our cars. I'm not real happy about it. From the NY Times, http://www.nytimes.com/2015/09/19/business/volkswagen-is-ordered-to-recall-nearly-500000-vehicles-over-emissions-software.html?hp&action=click&pgtype=Homepage&module=first-column-region®ion=top-news&WT.nav=top-news&_r=0
It was found that the cars would detect when it was being emission-tested. In normal operation, it would emit up to 40x over EPA limits for nitrogen oxides, a greenhouse gas and respiratory irritant. http://www.nytimes.com/2015/09/19/business/volkswagen-is-ordered-to-recall-nearly-500000-vehicles-over-emissions-software.html VW could face $18-billion fine for evading smog rules, cheating pollution tests - LA Times VW, Audi TDI Diesel Cars Had 'Defeat Device' That Violated EPA Rules, 500K Cars Recalled: BREAKING EPA Says Volkswagen Cheated On Emissions With 482,000 Diesel Cars (Updated)

I think a long visit back to the dealer and revised performance parameters (power, efficiency, and/or reliability) are now in his future.
Which would be right here: Official: Volkswagen's Clean Air Act violations on 2009+ TDIs triggers massive recall - TDIClub Forums VWVortex.com - NYT: EPA Orders VW to recall nearly 500,000 vehicles I can very much sympathize with them. They used the best info they had available and made as rational of choices as they could given the specs that VW presented as true.
The allegation is that VW/Audi installed on 4-cyl diesel engines from 2009 a defeat device (software which detected when the vehicle was undergoing smog testing and turned pollution controls on, leaving them off in normal operation). The fine could be up to $37k per car or up to $18B. VW has admitted to using the devices. There could also be criminal penalties and look for class action lawsuits claiming the cars, as retrofitted to remove the devices, do not achieve the advertised mileage.
So all this song and dance they made about diesels being able to match petrol for emissions was a total load of ****? No wonder European cities are dying under smog clouds when the manufacturers are saying their diesel vehicles comply, when clearly they don't. VW should pay for this. The German run EU will see that they're let off in Europe, but they should be punished, so hopefully the US will kick them hard.
Well, it's actually just VW's implementation on small engines. BMW, MB, and even bigger-engine'd VWs diesels that utilize a consumable "diesel fluid" (actually a urea compound in some sort of solvent) that is added to the exhaust, which neutralizes these NOx compounds. This does represent added complication, equipment, and of course purchase/maintenance costs... but it works. VW was adamant that they found a way to make a small diesel engine and emissions system without this consumable urea compound and all the requisite equipment and maintenance, while offering a more affordable car. Well, we now know that it was too good to be true.
