I've been noticing lately that when I'm driving my R at low speeds around 25-30 mph, when I let off the gas or I press the clutch pedal down while the car is moving, I hear a sound. It sounds like a little bell is softly ringing, almost like a brake squeal but alot softer. I have no idea what it is, hopefully that description is good enough to get some suggestions on what the noise is. The car runs great though, I just hope its not a sign of bad things to come. Thanks in advance!
