VW's skulduggery.

Besides what this company did, I'm sure they won't be the last. It's pretty amazing they kept the lid on this for 11 million vehicles.

How many think the engineers were basically told "If you won't do this I'll find someone that will."?

Perils of URL? That 3.3 million looks be be part of the 11M

Can't wait for FOX to report 44 million cars affected.

Sounds like the testing done could also be flawed

As I read, the software could detect when it was in test mode and on a stationary rig rather than driving under normal conditions. Why even bother doing this? Who, other than performance tuners, spends that much time running on a dynamometer?

Nothing like standardized testing.

That is, it lays the groundwork for ways to get past the testing.

yep

you can get evap failures past easily enough just by keeping the tank full so it never checks the vacuum pump, because it needs to be sure it won't pump up raw gas at/in top of tank.

Clear the codes, drive 100 miles, keep running, fill with gas, crank cycle 50 times to get rid of the "codes erased" code that rats on you, and it will pass Emissions Testing.

I agree, testing is deficient, maybe more....

...than any cheating. If I was at VW I'd fight them by demanding they test other similar vehicles in the same manner. Also would contest it on grounds that idling a vehicle is usually the most fuel efficient test mode anyway, so of course a road test would show increased emissions. Using the most optimum air/feul ratio and ignition timing settings for idle speed has been done even before electronic ignition, fuel pumps and injectors. There must be more to it like lying about road test results, because there is never any true comparison between road testing and idling, whether from tailpipe emission testing or taking OBD2 readings from the vehicle itself.

that seems to be what the focus is
"If it sensed that the car was being driven on a road rather than in a lab, it switched to a separate callibration which turned off the exhaust controls."

Not that it had an increasing but controlled emissions pollution, but that it "turned off" the emissions part entirely, leaving only the sensors required to create optimum power rating.

Clean Diesel

It sounds like Mercedes and BMW offered a similar clean diesel product, we'll see if they were the real deal.
