Tucson and Phoenix metro have yearly exhaust opacity tests on diesels going back all the way to the mid 60s.
I take my 190D in every year, and every year it passes under 1% out of 20% limit. Naturally aspirated diesels will almost never fail unless something is seriously wrong. Turbos will only fail if you've tampered with the the ALDA.
