Why can't the onboard computers and emission sensors in the car do their own
monitoring? Especially in NY if the State doesn't even test the actual
emissions. We are assuming that the car will meet emission tests when it
leaves the factory. I wonder if they even check it at the factory? If it
works when it is new and the sensors work then the car itself will tell you
(Service Engine light), or it should, that it needs service. If the check
engine light is off, the car should pass emission tests or what good is the
light anyway?

Of course you could always remove the service engine light and then it would
be 'fixed'. But there is always some way or another to screw up any system.

There are about four States that will not let a person own a Mercedes E
Class turbo diesel because they allow the sale of high sulfa diesel fuel in
their States. Like the few Mercedes TDI cars that are sold would make much
difference anyway.
