How far did you drive the car before doing the test? It should be driven at least 15-20 miles before you get anywhere near the DEQ. This make sure that everything is warmed up and operating at peak efficiency.

Last year I took my wife's 1995 E320 wagon with 50,000 miles on it to the DEQ nearest our house, about 3 miles away. It failed miserably.

Next day I drove it the 15 miles to the DEQ testing station very near my office. It passed with flying colors. This was totally due to the car being warmed up and all of the emissions equipment working well. Take it for a long highway drive before going to the testing shop.
