How is one supposed to know if the coolant temp. over a long period of time, not be 11 deg F above it. The coolant temp will saturate to the ambient temp. If the car is left to sit over night in a non-heated garage, it is highly likely that the coolant temp will be below 122 deg F. Regarding step 1 (cold start): The engine coolant temperature must be below 50☌/122☏ and above 6☌/11☏ of the ambient air temperature during startup. Not that anyone wants to have to cheat, but there are certain BMW computer experts who can set readiness permanently on some parameters.Thanks for the link. Where is it defined that three drive cycles must be complete where a drive cycle is defined as 25 miles at 65MPH and then idling the car for 3 minutes prior to engine shutdown?Īlso, Secondary Air Pump Monitor test is incomplete. All dash lights are off, except ASC-T due to traction control module being disconnected. Good to go for smog test :-).On my E36 M3 OBDII, my Evap System Monitor test is not complete, so I cannot complete a California smog check. It worked for me! I'll post the link where this instruction was posted from to give credit to the originator, if I find it again. While driving at city streets looking for parking spot at stop and go traffic, the evap cycle completed. With scanner plugged in (to monitor evap status) I followed the first two parts (25 miles 1/2 tank). I followed one suggestion saying drive for 25miles 65mph (on cruise control), with gas tank between 1/4-3/4 filled, and then park and leave engine on. I did recommended BMW cycle drives but evap still no-go After browsing through forums, youtube videos, etc.

No code fault from scanner and only EVAP is INC. My 2001 e38 failed smog for OBDII not ready. Old post but hopefully my experience will be useful. I don't see anything else that I have not done.Old post but hopefully my experience will be useful. I will drive it today and make sure it drops below 85% and get back to you. I noticed however that fuel tank is still over 90%. My evap system not ready is the only one left on my 2001 E46. I already failed emissions, but it had 3 systems not ready, now I only have the evap system not ready. I have completed the drive cycle a couple times already, but to no avail, fuel tank kept at half tank. '99 740iL, no engine lights, no codes, engine purring like a kitten, lots of power across the powerband. There's got to be a source of solid info on OBDII out there somewhere, but I haven't found it yet.I hope someone can reply to this old thread, I've been having the exact same issue with my evap system not ready. How heavily modified vehicles pass, I don't know. It's not definitive, but it was the best info I could find on the subject. I found info on some other makes while searching, and they all seem to be different in the details. JacksonMoto: I think that sheet is BMW-specific. I'll be digging into this more in the spring. I completed the drive cycle prescribed in the docs to the letter to no avail: system still shows "Not Ready." Does anyone have specific knowledge of the inner workings of how OBDII completes this check so that I can sort out exactly what's going on? Research has suggested that this is likely due to something in the valves or plumbing that make up the evap system. (Of course if that solves the problem, I'm going to seem quite the idiot, but I digress.) The procedure to complete this test is three minutes of idling on a cold engine - while I haven't specifically done this (I'm going to do it tomorrow just to be sure, but.) I'm certain that at some point in the last four months I've idled the car cold for three minutes. Basically I just want to understand the cause. According to what I've read, the car will pass NYS inspection with one check incomplete, so I'm not worried about that. There is no SES, no active or stored codes, and no driveability issues whatsoever. Trying to figure out why my car lists OBDII status as "Not Ready" due to Evaporative System Monitoring not completed.
