Volkswagen Is Ordered to Recall Nearly 500,000 Vehicles Over Emissions Software

The Environmental Protection Agency issued the company a notice of violation and accused the company of breaking the law by installing software known as a “defeat device” in 4-cylinder Volkswagen and Audi vehicles from model years 2009-15. The device is programmed to detect when the car is undergoing official emissions testing, and to only turn on full emissions control systems during that testing. Those controls are turned off during normal driving situations, when the vehicles pollute far more heavily than reported by the manufacturer, the E.P.A. said.

You can't get the staff.

All the while you have capable software engineers doing nothing.

They sound very capable, to be fair.

Tripos - 18 Sep 2015 17:50:48 (#3 of 567)

To be honest I haven't read the detail of this issue. My comment was more general.

MrNatural - 18 Sep 2015 17:54:49 (#4 of 567)

"doing nothing?" I'd say they did enough. What they didn't do is say anything, at least nothing so far revealed. Some communications about this will still be part of the company's engineering notebooks.

Sounds pretty bad. I wonder what they've thinking.

MrNatural - 18 Sep 2015 18:06:31 (#6 of 567)

Other people have had the idea. Back when I did contract programming for a car company powertrain organization, the idea crossed our minds, but we didn't. Maybe that was because at the time, memory was so precious.

I was going to say it was because we were so fucking ethical. But who knows? The EPA schedule was very well known.

chacqueschirac - 18 Sep 2015 18:10:04 (#7 of 567)

I can't see the benefit.

Tripos - 18 Sep 2015 18:10:58 (#8 of 567)

I have now read the header to the thread.

This is not apparently a thread about poor software, my apologies.

I do not know American legislation but I understood that as far as the UK is concerned a vehicle's ECU will permit the engine to run out of it's tightly controlled parameters in "certain" situations.

I am not an expert in this but maybe someone with more knowledge could elucidate?

MrNatural - 18 Sep 2015 18:12:04 (#9 of 567)

The benefit is that you can meet EPA emissions certs, which you must meet to sell a car in the US.

MrNatural - 18 Sep 2015 18:13:05 (#10 of 567)

And when you've satisfied those criteria, you revert the parameters you've controlled to limit emissions - to ranges which give you better performance.

MrNatural - 18 Sep 2015 18:13:23 (#11 of 567)

In other words, VW cheated.

chacqueschirac - 18 Sep 2015 18:14:14 (#12 of 567)

"The device is programmed to detect when the car is undergoing official emissions testing, and to only turn on full emissions control systems during that testing."

As they seem to be able to meet emission standards, what's the point of circumventing them? More power?

Tripos - 18 Sep 2015 18:15:42 (#13 of 567)

I expect so, and a "better driving experience".

chacqueschirac - 18 Sep 2015 18:18:10 (#14 of 567)

Teach them a fucking lesson.

AdrianNTierney - 18 Sep 2015 18:24:29 (#15 of 567)

Better performance AND better mileage, too.

MrNatural - 18 Sep 2015 18:26:25 (#16 of 567)

A lot of people here have their powertrain or engine controllers chipped. The result is indistinguishable from what VW did.

This means that you go to a speed shop and have the controller flashed with new tables of parameters. Ignition timing, fuel air mixtures, etc can be modified. Reflashing the controls happens via the OBD port.

Obviously, there is some collusion between car company software engineers and the companies producing the chipping software. You've got to know where those tables and parameters are located and WTF to do with them.

Tripos - 18 Sep 2015 18:28:31 (#17 of 567)

MrNatural, can I buy you a pint/or two?

Garden - 18 Sep 2015 18:31:41 (#18 of 567)

Why is this in the USA folder? Volkswagen is a German company.

chacqueschirac - 18 Sep 2015 18:31:55 (#19 of 567)

That's a ridiculous practice.

Why not just buy a more powerful car, if you feel your willy is too small?

MrNatural - 18 Sep 2015 18:34:14 (#20 of 567)

lol. Sure, Tripos.
