Humming Sound
Every morning when I open the door to my 128i, I hear a humming sound. I can't seem to pinpoint where exactly the sound is coming from, but it's inside the car somewhere and not inside the engine compartment. The sound eventually goes away after a couple of minutes. I'm not sure if the sound comes on every time I open the door, but then again, I park my 128 in the garage so I think it's just quieter where I can actually hear the humming. Has anyone experience this and can anyone tell me what it is...
