1997 e420 that wont pass smog????

I have a 1997 e420 that wont pass smog due to the computer not fully resetting. Does anyone know what causes this and what i can do? The mechanic i have said i need to keep driving the vehicle to get the computer to reset fully. I have driven over 200 miles and the computer is still not fully reset.

Thanks Adam

Welcome to the forum Adam.
Your car is W210 body and you will find more precise info in the appropriate section.
I drive diesel for last few years, but remember a topic with procedure that will reset computer in 1/2 hr. Look for older topics by ohlord.
