I have read a bunch of scary accounts about failing the new emission test that some states are conducting these days using the OBDII port in the car instead of the dyno. I heard that many of the S/V70s and possibly some 850s (do not recall what model years are effected) are unable to pass the test because of some status bit inside the OBDII memory not being in the state that allows the rest of the test to proceed. I am not certain of details, only that this is a problem with some combinations of test+car, car being various models including Volvo. In order to pass such a test a dealer has to drive the car in a certain way for a certain amount of time (and the moon must be blue on the following Tuesday, I believe) to set the bit such that it is acceptable to the test equipment. My question is: does anyone know what's the status of this issue? I realize that car manufacturers pass the buck to the test equipment manufacturers and test equipment manufacturers, naturally, pass the buck to the car manufacturers in a lovely vicious circle with us, the consumer, in the middle of it. I am wondering this because my '98 S70 is due for one of these next year (this year it was just "Kick-The-Tires" inspection and last year the OBDII was not yet available in Massachusetts and my car was actually dynoed and passed). If I am facing the this nonsense, I will have to plan accordingly, since I do not wish to be inside the vicious circle.
Thanks.
