I've got an interesting conundrum. My car is registered in
Massachusetts, where it just failed its emissions NOx. I took it to the
BMW service station in NYC (57th st.) where they ran a NY inspection on
it, and found there was nothing wrong with it.
The MA NOx readings were: NOx grams per mile = 5.44 with a limit of 3.00
The NY NOx readings are: NOx = 1.19 with a limit of 2.00
I guess its very possible that the inspection station in MA had faulty
equipment, and that's why it failed.
But I'm just wondering if anyone has any experience with emissions
levels in MA vs. NY and know for sure that if it passes in NY it should
be passing in MA.
Any resources online that could help decipher the difference between the
test limits would be a huge help!
