Recently i have been hearing these noises at low rpm that sounds like something is chipped on a rotary part. Something like a plaing card clamped to a kids bike so when the wheel spins you can hear it. Thats the best way i can describe it.

The sound is most noticeable when i am not driving fast an trying to consume gas efficiently by pushing the pedal as far as it can co without switching to the next gear.

The sound feels like its something plastic.

I have a 2003 A4 1.8T Q


Anyone recognize this? Thanks
