Mass Air Flow Wire Pigtail and ECM - (2009 BMW X5 XDrive30i)


New Member
I have installed a new factory Mass air Flow sensor but I keep getting a code saying that it is bad. I read somewhere that someone replace their pigtail and it took care of the problem. Does anyone know where I can get the pigtail other than a junk yard or the stealership? I have looked online but I am unable to find one. Also is it possible for the ECM to go bad and cause a check engine light to come on? I took the vehicle to a import car shop and they did everything they could to get the light off, replaced the O2 sensors and the MAF but I still get a check engine light on. They said something about the ECM could possible be bad. I am at a loss and I appreciate the help
