Can anyone shed any light on a strange noise my fn2 has started doing. It's usually when accelerating at lower speeds but can also do it when coasting. Only way to describe the sound is its a tinny scraping type sound. Similar to what a damaged bearing wound sound. It's been up on a ramp and checked over by an experienced mechanic, he found it comical as he had no ideas as to what it might be. Any suggestions would be greatly appreciated.
