Most states emissions testing requirements are not stringent. Having lived in Washington, Oregon, and California I can say that WA's and OR's tests don't do much.

This "hack" by VW should have been caught in weeks by the EPA. It was detected simply by driving the car around with a sensor in the tailpipe.

And yes, when emissions testing switched to relying on the OBD codes, all was lost. Even I thought about hacking the ECU to report "all good"

This intentional evasion of emissions standards couldn't have been caught by the EPA test process. That should be changed (which will open other doors for other ways to game the tests) but it doesn't have anything to do with VW's willful violation of the law.

They updated their testing shortly after announcing VW's emission violations. "Testing vehicles in new and unpredictable ways is the new normal"
