We'll have to see if Q5 TDIs will be impacted.

The lawyers are licking their lips.
Can you imagine the fallout? If they lower my MPG & HP they better write me a check for the TDI and take it away. How this is handed with determine if I purchase another VW product or not

Very upset with VW/Audi for doing this. It's unethical behavior of the highest norm, and while I'm not a fan of frivolous law suits, or an overzealous legal system, if the allegations are true, they deserve everything that gets thrown at them. If I bought a 2.0 TDI, and the recall zaps the performance, I'd basically be wanting a refund in full.

I'm also watching them very closely to see how they react.

We'll see. I suspect they'll do their hardest to limit damage to US Market. I think the CEO will survive, but I'd be stunned if senior heads did not roll in US.

I suspect there might be a longer term issue if the diesels will survive in the US market. Paris looks like banning them from 2020, and London is considering it. This dents the US market, and we may see a pull back from the TDIs.

This is an interesting read. They hypothesize that DEF/Bluetec is at the heart of the issue:>

Yes the issues is, the 2.0's do not use DEF or have an SCR system like the 3.0 engines have. Therefore they have higher NoX output. VW didn't want to add a DEF/SCR solution to the small engine therefore they just fooled the system. The 3.0 engines should be fine.

I wonder if Audi will still be replacing the engine on my Q5 for the oil consumption issue. They might not be able to afford it now.

The SQ5 TDI issue is because that car does not have a DEF system, but it will soon. Then, maybe, just maybe..

I expected it was due to lack of DEF as well, but the Passat had already been using DEF and the latest-gen Golfs (so presumably Jettas as well) have started (I was surprised to see the fill cap when we were looking at a Mk7 TDI for my wife), yet 2015s are included in the "affected" statement so I'm a little confused as I would've expected just the DEF-less model years to potentially be affected as it would've been a "transition" period where VW wasn't quite meeting EPA emissions but wasn't set with the changes to make it back into compliance.

Regardless, it's only the transverse 2.0 TDIs that are affected. All the 3.0 TDIs (which weren't advertising anywhere near the level of fuel consumption the 2.0s were) shouldn't have the defeat unit as the selling point isn't "huge MPG" so the exact number they can get isn't quite as important, and they've just recently been introduced (other than the Touareg/Q7), while the 2.0s have been around for decades and VW couldn't just drop them from the lineup without affecting sales a lot. So we shouldn't really have any need of worrying.

For now there is a possibility of 18 billion dollars in fines - we'll see what the final fine is. A disaster for VW/Audi's reputation in America and worldwide.

I find it very interesting that GM KILLED 124 people and injured 275 others and gets fined 900 million. VW puts some additional NoX in the air and gets fined 18 times the amount GM was fined and didn't kill anyone.

Pretty clear that the EPA cares more about air pollution than peoples lives when they are directly being killed by the actions of automotive companies. Anyone that doesn't think GM gets a "pass" from this administration is fooling themselves. 40 Billion dollars in unpaid loans forgiven and now this...

(Meanwhile China dumps more crap in the air than anyone on the planet, by a large margin)

Yup, the Mk7 Gold has it now. Here is a good article on the whole thing for those of you confused.

Doesn't help my confusion since the Mk7s are included as being affected yet they've got DEF now (unless it's simply a matter of the software not having the emissions check removed -- it'd be pretty bad if they still couldn't meet emissions even with DEF), as well as the Passat which I believe always had DEF due to the size. Unless VW went really crazy and used the DEF to push performance up while emissions stayed the same overall or something like that (in which case that's much worse than the sympathetic cause of "the EPA's really dropped the acceptable amount of NOx and we need to do a redesign to meet it").

That being said, it at least seems like Jalopnik's got a fairly even take on it, not falling on either end of fanatical, which is good to see. Hopefully it's handled with a minimum of headaches for owners and VW can start working on repairing its reputation. They shouldn't've broken the law, but I know the EPA's extremely hard on diesels so I can sympathize with manufacturers trying to meet the requirements that sometimes change dramatically. (If the Mk7s are truly in the same boat despite having DEF, though, that's just unacceptable.)
