Ok so i live in illinois. This past winter i bought my Euro 240D. so i had no real use for my 1997 Nissan altima, except for when it snowed or i thought there was alot of salt on the ground i would drive that and leave the Mercedes in the garadge. During june of 2005 until January of 2006, the check engine lights would come on and off, long story short, after getting the final notice in the mail to have the emmisions checked i took it there and it of course failed, bad knock sensor. While i was there, i had told the guy that i recently purchased a Diesel mercedes and asked him what the emmissions requirment was for it. he told me that in Illinois that diesels do not get emmission check and if i receieve and emmissions letter in the mail to take it the emmissions place so that they can make sure it is 100% diesel and i could be on my way. my questions is, does anyone know if this is 100% true??

yep,

Even with the talibans of the republic of Kalifornistan you don't have to check emission for diesels. yet another cool perk of the diesel cars!!!

Depends on the state. In Oklahoma, my car never got an emissions check. Here in Denver, I have to test it yearly.

EDIT: From the Illinois Environmental Protection Agency’s website-

------------------------
Exempt Vehicles

* 1967 and older vehicles.
* Vehicles registered as antique.
* Diesel vehicles.
* Farm vehicles.
* Show cars.
* Ceremonial vehicles.
* Motorcycles.
* Electric only vehicles.

Diesel Vehicles

Emissions from some diesel-powered vehicles are very visible and questions are frequently asked about why diesel vehicles are not included in the Illinois Environmental Protection Agency’s vehicle emission test program.

Diesel powered engines produce different types of emissions than gasoline powered engines. Diesel exhaust contains relatively insignificant amounts of carbon monoxide and hydrocarbons. However, the particulate matter contained in diesel exhaust can be a health hazard.

Equipment used in the test stations to test for carbon monoxide and hydrocarbon emissions produced by gasoline powered vehicles is considerably different from equipment used to test for particulate matter emissions produced by diesel powered vehicles. Typically, an opacity meter is used to detect the volume of particulate matter in diesel exhaust. Diesel exhaust can actually damage the analyzers used to inspect gasoline-powered vehicles. Many diesel-powered trucks are registered in areas that do not require emissions tests, and travel through many different ozone non-attainment zones. Efforts to reduce emissions from diesel powered vehicles have mainly concentrated on technological advances in engine design, which required a 95 percent emissions reduction during the first half of this decade.
The Illinois Department of Transportation and the Illinois State Police inspect diesel vehicles for excessive diesel emissions. For more information on the diesel test program, contact the Illinois Department of Transportation at (217) 782-5597.
