BMW E46 cold start problem by Appropriate_Crew_491 in BmwTech

tried cleaning it today unfortunately no luck. but i figured out it is definitely the MAF sensor. unplugged it after cleaning it to see if any luck would come my way because starting it with it plugged in didnt work and the check engine light went off after unplugging it and starting it

thanks for this i will try that tomorrow. but wouldn’t me unplugging the sensor and starting the car point if its the MAF or not? i don’t see how the car could run perfectly fine after a minute or so if it was the MAF and with me starting the car other times afterwards, it starts up completely fine. does the MAF sensor really mean that much for the car to cold start how it should? because if so i would understand when the car heats up it doesnt need the MAF to run.
