I suspect no money found its way into the hands of the engineers. Only the VW executives would have gained. The engineers were probably just following orders.

I wouldn't mind being one of them. There's nothing unethical in avoiding government standard and commercial consequences are all on management stuff which made the decision.

I disagree. It was unethical. The ACM's code of ethics and professional standards says:
1.03. Approve software only if they have a well-founded belief that it is safe, meets specifications, passes appropriate tests, and does not diminish quality of life, diminish privacy or harm the environment. The ultimate effect of the work should be to the public good.
What VW did drove a cart-and horses through that one.

From my experience in large companies, I can tell you that the instruction to write the specification in this manner, most probably came from a high level in the organization. In any case, top management may delegate responsibility, but they cannot delegate accountability. Regardless of whether the top man knew about the cheat, he remains accountable for the actions of his underlings.

You're disappointed that engineers are also people?

No - people make mistakes for sure. But for this to happen a whole gang of people had to collude in doing something which should have set all their inner alarm bells ringing.

I'm not talking about mistakes as this probably wasn't a mistake.
I'm talking about the evil that men do (which lives on and on[^]).
This is one of the lesser evils that probably filled the pockets of quite some people.
And they would've gotten away with it too if it weren't for those meddling kids!

There's nothing surprising at all about this. In my 30 years of coding I've met all manner of unscrupulous developers who only care about making money and don't give a rats arse if the code they write is right or legal.
I wouldn't be the least bit surprised if this came straight from the top.
If it's not broken, fix it until it is

Yes, I've seen it too. I see it from employees who don't care and consultants quite frequently.

How can you know whether what you write is legal, unless you know all the applicable laws and bye-laws for for every country in the world?
Globalisation has a downside where we as engineers cannot know everything and are very likely to be reliant on market experts to know the laws we have to comply with in their target geographies.
|
|

|

Yes but what we have here is something that is patently wrong by anyone's standards. The code was deliberately designed to cheat during the emissions testing. It's not a question of not knowing the local laws - they knew the law and deliberately flouted it.
|
|
|
|
|
That's the point they would have known at a minimum that they were 'working around' the law, but certainly in some places (thinking UK here) the law is poorly worded.
In the UK the test rules use terms like 'at the time of the test', while the term is meant to mean that the driver couldn't be prosecuted 10 months after the test if their emissions had crept up, some corporate lawyer type can use that clause to mean that what VW did is not illegal. Clearly morally incorrect, but legally okay, it should be caught by a 'no specific changes for the test / test being representative of normal running' type clause, but the diesel tests in the uk have been messed up pretty much since emissions test for diesel were introduced.

Don't know about other countries but, in the UK the emissions are tested by sticking a pipe up the exhaust - I read that the software knew when the emissions were being tested HOW ? that implies any time someone stuck a pipe in its exhaust the engine would run in clean mode Anyone shed any light on this ?

Google that question and you will find the answer.
My understanding is that when testing, the steering and use of accelerator pedal of the car match a certain pattern. The software looked for that pattern and when it saw the pattern it put the engine into a mode where it was less fuel efficient and worked at a hotter temperature reducing emissions - please pardon my less than scientific explanation

When my car was checked at the last (mandatory) checkup, they plugged in some diagnostics equipment and also monitored the values from the car's chipset. The interface supposedly was a standard across all manufacturers. If a special clean mode exists, it would be a good time to start it when someone connects to this interface.

OK - I've only seen diagnostics used this way by mechanics err diagnosing - but as you say a perfect time to trigger it

We have mandatory checkups every two years. If you don't go to the checkups or if the car does not pass the tests then its license will be void and the next cop driving behind you will pull you over.

I wrote a blog[^] about the very same issue recently.
"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." - C.A.R. Hoare

Isn't the DPF cheating too, I mean if you measured the emissions as the DPF was regenerating it would be off the scale. I don't think people buy diesel cars because they are green and have low emissions, they buy them because fuel costs are lower.
I just don't get it. The whole thing is a "storm in a teacup"

I don't think it's a storm in a teacup, as actual harm has been done. People have been duped into buying cars they might not otherwise have purchased (some people do care about the environment). People with respiratory problems have suffered from the increased NOX emissions, and investors in VW have lost a load of money. And probably VW will start announcing lay-offs soon due to the impact it will have on their sales.
