VW caught cheating on emissions

DOJ had better be initiating a fraud investigation.

And this has been done before - by the HD diesel engine manufacturers. They got nailed bad and one result was that they had to implement new standards several years before they were required.

This is on a much larger scale than even the GM ignition switch issue (active plan to violate regulations, not sloppy design and then shove it under a rug).

 

But wait - our congress will probably try to come up with some sort of "german exemption" again.

And you know what else?

 

This is going to destroy VW's car sales (slight exaggeration)

 

Know why?

 

Because every last one of those offending vehicles will have to be reprogrammed to run perpetually at the cheat setting. That means titanic losses in FE (and probably power) for VW owners everywhere, and no realistic hope of getting that mileage back. Think those people are going to buy another VW?

I thought I'd read the OBD was putting out (intentionally) incorrect data, when it detected the test was being conducted; NOT that it was altering the tune of the engine.

Yeah, i'm still not clear on this either - I thought it was a different tune originally, but more recently read something about the OBD output. Either way, there must be a big reason for VW to have cheated like this, and if it's not fuel economy, then it's probably going to be reliability.

 

It definitely explains a few things, biggest of all - why the internet clamours for diesels and nobody seems to bring them over other than VW.

VW is telling its U.S. Dealers to not sell what they have already on lots

That is a 24-carat a-number-one steel-belted gen-you-ine admission of guilt right there.

 

If VW KNEW there was no substance to these accusations, they would not order a stop-sale.

Since there IS something to them, they know that EVERY sale adds to their fine.

EPA rating emission testing is based on actual emissions collected in huge bags.

 

I don't know what OBD data is reported, but that could be for annual certification checks.

And if the EPA was smart here, they would approach the EU and say, "this is jeopardizing reciprocal recognition of emission standards,

please audit VW diesel records and confirm the validity of all submitted data.".

 

The EU is joke, it simply shallow audits to find nothing wrong with supplied data and then rubber stamps those results.

Volkswagen finally got pinched. It is not news that they have been cheating, most all the VW tuners know Volkswagen has been cheating with this for years. But that they finally got caught.

 

What VW did was increase the EGR output when the OBD was plugged in therefore reducing the NOX output. When off testing the EGR output was lowered. This is quickly verified by tail pipe testing with the OBD hooked up and then when it is not. Naturally reducing the EGR flow is going to give you jump in F/E and power. They did not cheat on the emissions equipment but cheated on the programming. The fall out form this is going be huge for VW.

 

VW is not the first to have cheated on emission testing and likely wont be the last. Just about everybody Ford GM AMC Chryco Honda Yota etc etc got nicked at some point and time, mostly in the 70's. Just now the legislation really has some teeth to it and it is not just slap on the wrist like it used to be. Most were nailed cause they had "specially prepped" vehicles for EPA testing. After that fiasco the EPA started to pull random production vehicles to verify what was originally supplied by the manufacturer.

 

I imagine we are going to see a bunch of legal wrangling here similar to what Cat did when they got busted. I can see VW claiming it was an accidently missed line of code that was not deleted after power train development. That will likly be their claim to try to mitigate the "intentional" aspect of it. Unfortunately it will be on the EPA to prove it was intentional and not just an error. They will have to look at the programming in EU spec ECU's to see if their is a similar "anomaly". I know and we all know VW has been cheating but the tough bit will to prove it was intentional, and with the U.S legal system this is not going to happen any time soon.

 

Why did VW cheat, It is not some big conspiracy it was simply to reduce deposits in the intake, the better power and F/E was just a bonus from it.

Intake coking is something EGR VW diesels have always suffered from. Lots of back yard how to videos on You Tube for cleaning earlier VW diesel intakes, Lowering the EGR cycle reduced the rate at which deposits form but it also drastically increases NOX. The reduction in carbon deposits would mitigate warranty issues, drivability issues, and reliability issues (not sure how it can get much worse it is VW) And really this was a stupid ass thing to do since the real fix would have cost them about $20 (if that) a vehicle and that is to pull the EGR feed post DPF once all the soot has been dealt with just like other manufactures are now doing.

 

 

Intake and intake valve coking (carbon deposits) are going to be an issue for many manufactures. DI gasoline engines have this issue. And it is cropping up in the Eco Boost line of engines. The fix is simple for DI gasoline engines and has been in use by various manufactures for about a decade now, Ford neglected to add it to the Eco Boost line, as it is not a cheap fix but it solves the issues of intake valve coking once and for all. It requires the addition of a small secondary port mounted fuel injectors that wash the back of the intake valve and stop the carbon build up. Several manufactures are doing this on their DI gasoline engines.

 

Every one knows this intake valve deposits are an issue with direct injection gas engines and has so for over a decade now. I'm disappointed Ford did nothing to mitigate this issue in the Eco Boost engines and then claimed ignorance when the associated drivability problems that arise from it cropped up. Part of the reason I think the Ford power train engineers as of late are muppets as they are either negligent or stupid, to not address this most basic inherent gasoline DI issue in any manner at all with either auxiliary injectors or an intake service interval.

 

Regardless VW deserves to have their ass handed to them. And really not so much for cheating as everyone has done it (and some still are, VW won't be the last ones busted) , but for being so fricken stupid in the first place.

Does a decision like that belong to the VWNA head though? That seems like an awfully big risk that guy would be taking for it to not come from the top? Or maybe I'm the only one that thinks that?

In my experience a course of action of a large operation requires oversight at least or approval. This looks like VWNA is getting thrown under the bus. You probably can't prove it but nonetheless, I find it difficult to believe that the head shed had no idea.

Yeah that's what I'm saying. Imagine if it comes out they're doing the same in Europe...

Oh yes, I'm agreeing with you. I also think this may be a tough case to prove and that could take a while to finish (if at all). IF this blows up in their faces, it make the GM ignition switch and the Ford 'fire sale' seem petty. If this turns out and I'm a little rhetoric here, it's one for the history books.

Whoa.

 

Around 15 billion euros ($16.9 billion) was wiped off the market value of Volkswagen AG on Monday following revelations that the German carmaker rigged U.S. emissions tests for about 500,000 diesel cars.
By early afternoon trading in Frankfurt, Volkswagen’s share price was down a stunning 19.4 percent at near three-year low of 130.20 euros. Its dramatic fall weighed heavily on Germany’s main stock index, the DAX, which underperformed its peers in Europe with a 0.6 percent decline.

Whoa.

 

 

 

 

Just came to post that.. couldn't believe it when I read it this morning. Boy that has got to hurt!! Wonder what will happen in the upcoming days.

 

Didn't include a quote so I'll link one that talks about it.
