My old man has a 2003 E46 M3. Lately he's been complaining of a squeaking and/or grinding noise coming from the rear of the car. He says that the noise isn't evident all the time, maybe a few times a week on his commute to and from work. He says it sounds like it metal scraping metal. Does anyone know what this noise is and what needs to be done to stop it?
