How far is this VW thing going to go?

Fox was there anything to suggest the software fix is going to anything other than remove test mode?
Will the car basically be the same, pumping out the same as it does all the time, but not enter test mode anymore when it detects a test setup?

I can't see the point of removing the defeat devices because it's only used when the car is tested before sale. Removing it note will serve no purpose so it won't be what they are doing. The only option I can imagine is to retard performance so that there car meets the expected emissions standards... In other words make your car slower.

I would be refusing to let VW do that to any car I owned unless I was legally obliged to do so? Not that I have ever, or would ever, buy a diesel however.

Even if it didn't foul eu tests, did they advertise NOx emissions to EU or public, was NOx tested at all, if it was they still cheated and EU will not like that, even if it would have passed without it. I think this will be bigger in the EU than those who are saying its a us only issue.

Not sure if this has been mentioned already but when this first became known I thought many other manufacturers would be next in line, anyone know why this isn't the case?

Can't only be VW that were up to this.

Missed that.

Still, not quite new fuel tanks, no idea what that idea would have come from.

Maybe reduce the size of the fuel tank so it can carry a bigger tank of that emission reducing chemical or whatever it is

Most of the other manufacturers are using expensive AdBlue systems to meet US emissions standards. VW were not...

Aye and now VW are, the new Audi A4 launching at the moment has a gubbins tank in addition to one to make the car actually go.

Afaik every manufacturer has had to put pee tanks on thrir fiesel cars if the have a bigger engine that 1.6 in pder to psss euro 6. My bosses q7 has one

Source? I thought the had adblue and the cheat thry used wss thst on sensing testing in added way more adblue than normal?

Since every vw needs an adblue tank to pass euro 6 icant beleive vw would try and get their cars past the us tests withput one?

Both have been reported early on, I think it's been clarified that it was actually that they weren't using AdBlue in the US though.

Bear in mind the US cars in question wouldn't have been subject to Euro 6 here, the time frame means they would have been tested to Euro 5, which no one needed AdBlue for.

Most likely scenario seems to be that VW tried to be cheap and get away with not making a US only AdBlue version of their EU5 cars as others were doing.

There isn't an issue with newer cars that are being Euro 6 tested, they're meeting US standards without cheats (using AdBlue now).

Errr any manufacturers website? It'll tell you if the car has AdBlue or not.

I have no idea what that sentence says. Older VW 2.0 TDI's do not use AdBlue.

This issue affects Euro 5 cars, not Euro 6. Euro 6 is a recent standard, Euro 5 goes back 5+ years.

Greebo · 12 Oct 2015 at 23:26

I thought the us tests where the same levels as euro 6?

Hence in order to get a car through the us tests you would have to use whatever you needed to do to get through euro 6.

Hence if vw could get their Euro 5 cars through the us test they wouldn't have needed ad blue to get through the euro 6 test?

And sorry I was typing from my phone earlier in the cold and outside and didn't have my glasses on. But seriously, I'm sure you could get what the rough meaning of the sentence was so don't be so sanctimonious

Greebo · 12 Oct 2015 at 23:44

Just checked the US test vw cheated on are more stringent than euro 6. How the hell did very expect to do it without ad blue?

Uh oh, some petrol cars are also affected

No, it says they couldn't be ruled out - not that they are affected.

Jono · 4 Nov 2015 at 14:20

Bet all the major manufacturers have been at this. It'll all come out in an even bigger scandal, just like TV / Radio presenters and politicians and their botting of small children.

I got a letter from the Seat main dealer regarding the car I bought from them in May which is affected. 1.6L Diesel Ecomotive. Tried contacting consumer direct to see what their take on it was but they were so overwhelmed with queries around this issue that they're just taking details and having to call people back. This was 3 weeks ago.

I'm not sure where I stand with this as I worry that I may end up with a car that has higher and more repair bills, affected performance or fuel economy. Of course I may not, but for someone who doesn't know a great deal about cars I don't know where to get answers. I read a lot of conflicting stuff on the internet.

Jokester · 4 Nov 2015 at 20:05

Have they actually come out and said what the impact on performance/economy will be from the "fix" or are they literally just removing the software so that does the cheat so nothing actually changes?

How can they "discover", or "can't rule it out"? It's not something that happens unintentionally is it. It is done as far back as the design stage all the way into manufacturing.

They have to know it from day one.

No, I don't think they have, I've just read there is a possibility that economy and performance could be affected, especially in the case with the 1.6L engines (like mine) that supposedly need fuel injectors as well as a software update.
