Default EPA caught VW cheating - how does the car know it's being tested?

Sure will. You have to enter the VIN into the system to start the
inspection. IF the EPA requires a recall to reflash the ECM to
remove that software and "correct" the problem, that would have to
be done at a dealer. They will track completed vehicles by VIN. The
state can just flag ALL those vehicles. You pull in, they plug in
the tester, and your VIN doesn't show on the "recall complete"
list. You don't get inspected. That has happened before for other recalls.
I'm betting the fix
will be to re-flash the ECM software to remove the "switch". Then
run each one through the full EPA test regardless of registration
state. That because this if a federal law that was broken.

What will be fun will be watching all the johnny racer types who
modified the cars by removing emissions gear and "tuning" the ECM.
VW could actually show them to the EPA and say "THEY removed the
systems so they should pay a fine as well".
When has the EPA ever gone after individual passenger car vehicle
owners?

Happens a lot more than you might think. States get into the act under
the umbrella of the EPA laws.


VW intentionally wrote software for their vehicles with the express
intent of violating the EPA laws. They admitted to that already so it
will be interesting to see what happens. The EPA could recall the
cars, judge them as "unrepairable gross polluters" and have them
crushed. I doubt they will go that far but they have done it before
under the "cars for cash" BS.


Or, the EPA could require that all the cheating cars be re-programmed to meet
requirements all the time, and owners could sue VW's ass off for cheating them,
since the resulting performance will be terrible.



I doubt they will be able to sue. The "normal" EPA test numbers for
these vehicles have alwas been "low" compared to the ones outside the
lab. I hear folks all the time bragging how their VW gets 45 mpg but the
sticker says it should be getting 38 mpg. VW can re-flash the ECM and
simply say the the TEST (remember the tests would have been with the
emissions systems working)mpg is the correct number and their 45 mpg was
a fluke.
