Failed emissions, again, 2yrs in a row

[uisim]

So my last emissions I had to take the e92 M3 to the dealer because all monitors were not ready. Not bad 200$ later they said they did something with the same and passed it for me. This time around the o2 monitor reads not ready no matter what I do. Followed all the cycles to the t, used inca to check codes and nothing. Anyone have this issue? What was the outcome?

Do you have stock xpipe?

Were gonna need a lot more info to help you. Lets start with, what sensors are showing not ready? Have you modded anything tune or exhaust wise? What is causing your sensors to be reset over the last year since your previous issue?

After a system reset, a specific drive cycle is necessary to get sensors ready. its very particular in how it must be done. Assuming you dont have any issues with o2 sensors, evap system, cats etc, it works for me every time and I can do it in 30 mins max. Sounds like you know this since you said you followed it to the T. Be sure you dont exceed 3000 rpm and that you are gingerly using throttle at all times during the readiness testing.

Considering your situation, it is highly recommended you pick up an OBD2 reader and do your own check using Carly or another sw solution BEFORE you try to go get your emissions run. Save yourself the headache of failing again and again.
