Exact W211 Drive CYcle
I recently failed smog as a result of Evap and Catalyst failure. I have found exact drive cycles for other chassis designations but not for the W211. Can anyone help??
And to save time, "Just drive it for 60 miles with varying speeds" is not the answer I am respectfully requesting. I replaced both batteries 2 months ago and have driven for over 200 miles, pass smog on all other points. I need the exact specs for W211 drive cycle. Thanks!!!
Evap failure could be a bad hose or gas cap. My Durango has a CEL for that currently. I just replace the ****ty aftermarket hose to the evap canister a month or so before it needs a smog. They last a few months before splitting and throwing a CEL again. The OEM ones lasted 10 years. I should just go buy them again.

Las Vegas office takes me in after about 3 minutes with appointment.
In California even with appointment it still come close to 1 hr.
Most of my cases require vehicle verification and I don't think AAA can do that.
Now coming to drive cycle, I got catch on it as well. Turn out that when I shift to D about 2 seconds after turning ignition on, the cycle require some idling.
Peach link shows short version, while google will find you official OBD requirements.




!!! That did the trick!!! Passed with flying colors, then spend 2 hours dicking around at the DMV.... at least that's done!!!
