| | Strange Noise
Alright so I have noticed that in my 2003 325i when I am driving from a dead stop and pass 30 mph I hear a 1sec vibration noise coming out of the air conditioning. As I pass 45 mph I hear it again. Similarly when I come to stop at a light and the mph slow to 0 the vibration noise comes in again around around 25mph. When I turn off the air no noise.
What should I tell the dealer is wrong with my air conditioning. Sounds like a belt needs to be tightened or something?
