See post #78. If VW were running the tests, well we already know they are cheaters.
Talk about destroying a brand. What a fiasco.
My first (real) car was a used Scirroco:
It ran well, even though my friends said it was a 'beater' I loved it.
Sad.

Volkswagen is confronted with a monumental challenge.
The company has admitted that 11 million of its cars used illegal software to cheat emissions standards.
Now, many owners are demanding that the offending cars be fixed.
That's easier said than done, and Volkswagen has already tried — and failed — twice.
Here's the issue, according to the US Environmental Protection Agency: Cars with Volkswagen's 2-liter TDI turbo-diesel four-cylinder engines include software that detects when the car is undergoing emissions testing and turns on a suite of pollution-control systems.
But as soon as the test ends, the controls switch off, leaving the engine free to emit up to 40 times the legal limit of nitrogen oxide, a highly polluting gas. According to the California Air Resources Board, Volkswagen admitted to using a defeat device during a September 3 meeting with the agency and the EPA.
The problem for Volkswagen is that getting the engine's emissions in line with pollution standards probably means sacrificing something else.
"Building an engine involves balancing four factors — performance, emissions, durability, and fuel economy," explained Jake Fisher, Consumer Reports' director of automotive testing.
Right now, VW has sacrificed emissions to create a TDI engine that offers great performance, incredible fuel economy, and solid reliability.
"Whatever the fix is, it will likely sacrifice fuel economy and probably durability as well," Fisher said.

My question is how has the VW diesels on the road since 2009 have been passing state emission tests?
Lets do both. They are two separate issues. I dont like lying companies tricking people into buying what they think they are buying but arent, and i don’t like the epa either.
Separate issues. I am up for dealing with both of them.
In either case, either the EPA has never spot checked a Volkswagen TDI since 2009, or else both spot checks of emissions and mileage were close enough to the numbers submitted by the factory.
Remember that it was not the EPA that caught VW.
How far back does this go? I do not know.
I would have thought so, too, but I checked Craigs List and it didn’t seem like prices have come down.
I think in all likelihood they’ll have to come up with a fix to make the car emissions cleaner. Then probably pass an exemption grandfathering the cars in while sticking VW with the largest fine ever issued.
I think part of the programming was gaming the ppm by diluting it with extraneous airflow. Since that’s a cheat of sorts, there’s no programming solution.
Yup. Less than 1% — that is because of the cash for clunkers program of a few years ago. Perfectly good well running cars and trucks were crushed in the compacter and engines destroyed all because of a freebie from the government. Very wasteful IMO.
People had a car that was paid for free and clear, now they have a car that isn’t paid for and probably a $20,000 loan.
I didn’t fall for the CforC scam and am still driving a 1993 vintage car — bought, paid for, and owned. A few scratches and dents but I OWN IT! It runs great too. We are still required to pass emissions and it seems to do okay. I think that the cut off was around 1969.
You see cars with the vintage/antique license plates that predate 1969. Vintage/antique? LOL. They are not antiques and are true clunkers but the owners don’t want to have to deal with the emissions tests. Don’t blame them, though.
That NoX emission is tied to combustion temperature, which is related to fuel injection timing. Advance of injection timing relative to TDC increases peak temperature and pressures, which increases NoX quantities produced. A multi-step injection profile limits peak temperature and is a common NoX control avenue.

This was my thought. If the cars meet the standards at time of testing,doesn’t that meet the letter of the law? The other thing is the oppressive ideas from the gov’t./EPA. Do these people have a clue what they are doing? They are supposed to be working for us,not the other way around.
Maybe it's time for VW to be a world leader and get HCCI technology commercialized in the next few years, especially now that engine computers and pressurized direct fuel injection systems are very good indeed.
I am trying to guess how the car knew it was connected and being tested
It can only be through the electronic interface, and something in that interface says “I’m connected”
That would turn on/off the cheat.
I almost bought one of these things- I did a test drive over a weekend and I got nearly 80 MPH on the thruway. the dealership was a bit miffed that I put 400 miles on it
Is it mostly that the US wants to exclude diesel cars from the market?
My prediction is that would not fly in some states, such as Kalifornia, and folks won't be able to re-register their cars.
I'm not buying that. Just about every engine and electronic parameter on these cars is software controlled. A firmware upgrade with new emissions programming will be an easy cheap fix for vw.
Performance and fuel economy will no doubt take a hit, but a programming fix is very doable and cheap.
And owners want that "fixed"?

They did no such thing. They took a gasoline engine automotive block and made it into a diesel. They were complete POCs with terrible longevity.
Even worse. Thanks for the memory flog. Gas engines aren’t built for that pressure, are they?
