OBD2 Readiness Monitors/Aircare Hey guys, Well as some of you may or may not know, the E39 M5 are succeptable to carbon build up issues in the secondary air flow system. I have since addressed the carbon build up, but i am having an incredibly hard time resetting all the readiness monitors. Ive done like 500+KMS and like 6 cold starts, ive tried all these driving procedures. So far, the Catalyst, Oxygen Sensor, Secondary air, Evap monitors have not set themselves, while the Heated Oxygen circuit, EGR, AC refrig and heated catalyst have set. I have no codes present, ive replaced all spark plugs with NGK Iridiums, new MAF sensors, Cam sensors, pre-cat Oxygen sensors, Oil seperators, oil seperator hoses, air filters. car runs great otherwise, but it sucks, not being able to set the readiness monitors i am unable to even go thru aircare because i just get rejected. They wont even test me. Is there anyone who works at aircare who can point me in the right direction? I figure you guys see this type of stuff all the time, maybe you know some tricks to help speed up the process to get these stupid readiness monitors to set? thanks in advance! |
what year/model bmw. I can find the driving procedure for you. |
Its a 2000 BMW M5 Thanks man!! |

Looks like it could be my ECU. There were a couple people in the states with the same problem after the reflash. I tried the driving procedure but nothing helped. Thanks for the help anyways. |
Yep it was my PC Reflash. Turns out they turned off my rear o2 sensors for some reason. Perhaps the reflash went wrong. Made it thru, thanks guys! |
