I replaced my bad air pump along with the automatic valve on my 04 e46 m54. Unfortunately, I need to get it through emissions by the end of January. I had this car since new, and was just giving it to my son who got his license yesterday. The ses light will stay off for a while, but sometimes will come back on just as the air pump cycles off on a cold start. I have cleaned the airflow sensor.
I really could care less about the light for that, but I just need to get through emissions here in Maryland. I had the light off for a week, but still showed as "not ready" at emissions.
Any clue why the air pump triggers at shut down?
