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. -- Steve W. |

Don't know how other jurisdictions do it, but in Ontario the old "drive clean" test was a "rolling road" sniffer test at two speeds, with the car connected to the computer via the diagnostic port, but not accessing discrete codes. The new system does away with both the "rolling road" and the sniffer, meaning it can only "guess" or "deduce" if the NOX is within range - it cannot tell if the reduction catalyst is working because only the oxidizing catalyst is monitored by the secondary O2 sensor. It is POSSIBLE that VW implements the "over-ride" whenever a certain sequence of events is performed that are substantially the same as the initialization procedure for running the test (There is a perscribed sequence of events that MUST be performed to get a valid test result) (like 20 many seconds at a particular RPM, followed by another given period of time at another RPM) which, if performed during the normal process of driving would also put the system in "bypass" for the anticipated duration of the test. |

My guess is that >the "fix" will be a downgrade of some kind. Then how do you explain the FACT that todays engines - 1)produce higher spedific output than engines in the past 2) Consume fewer gallons of gas per unit distance travelled AND 3) produce lower exhaut emissions -than the engines of only a few years back - muchless the "uncontrolled" engines of the 50s and 60s, and the early emission engines of the 70s and 80s? VW will just have to step up to the plate and spend in retrofits what they should have spent in initial design and production - plus. >- >. >Christopher A.

But the EPA will be the only route by which this could be addressed given that many states don't even do testing. |

These two concerns are best >addressed at time of manufacture. I will respectfully dissagree - with qualifications. In the early years of safety checking, at least in Ontario, the initial passs rate was quite low - and the requirement that a cat pass a safety check when changing ownership took a LOT of dangerous crap off the road. Annual safety checks in Ontario only affect commercial vehicles - and again there is a pretty high failure rate - and since selective enforcement has been in place the number of wheels coming off commercial vehicles and killing drivers of other vehicles has dropped SIGNIFICANTLY. Enforcement is the key. As for emission testing - in the early years it had merit. There were a LOT of "gross poluters" on our roads - and it was very simple to defeat emission controls and change the calibration of an rngine (by adjusting timing, rejetting carbs etc) so that what left the manufacturer and what was on the road were not necessarilly the same. With today's computer controlled vehicles, unleaded gas, etc, the VAST majority of vehicles pass, even when 20 years old - if reasonably maintained, and the OBD2 only testing is a total farce and nothing but a money-grab - Safety shecks for vehicle transfer and annually for commercial vehicles is both a consumer protection AND safety issue - and worth continuing. (along with "selective enforcement" on the roads - see a "questionable" vehicle - pull it over and inspect it for basic safety standards, and possible send for "secondary inspecion" by a registered safety inspection station. Bring it up to standard or take it off the road. |

Spot checking of modified vehicles at large "car shows" has been promised, and reported. Just because your car is registered as a 1927 model "T" ford does not mean it is exempt from emissions testing if it has a 2009 Chevy LT between the frame rails. > Officially it needs to meet the requirements for the 2009 vehicle the LT was originally supplied for (determined by the engine number). >> VW intentionally wrote software for their vehicles with the express >> intent of violating the EPA laws. > >Yes, I know.
