This noise has been bugging me for nearly 2 years now, over that time it's slowly been getting worse. Started at about 60,000mls and now at 90,000 miles and its worse. The noise is worse when the belt is under load, like with A/C on and heated windscreen the noise is much louder. I did take it to Ford but they just said its the "FEAD" belt, and recommended replacing the belt, however I don't know if it is the belt itself. Any ideas?
I've attached a sound clip of the noise
