Anyone have a printout of the drive cycle for a 1999 Mercedes C230 handy, or a link to it. This is maddening trying to get this car to pass smog.

PTVC230K

Went through this last year for a fault in the instrument cluster.
Following a reset of everything and a new instrument cluster, it took about 400 miles before the cycle times were reset for me.
I know it is not just miles, but warm up cool down a certain other conditions. I did all I could to help it get more warm and cool cycles, driving it out for meals after cooling down etc.
Never did find anything official in my service manual, nor conclusive on line that was what actually happened.
