Hi I have noticed a strange noise when letting off throttle , a almost metallic noise it only happens when let of throttle, including when I'm stationary revving it or even when moving. I have attached a clip of the sound when revving stationary, any help or guidance if I should be worried or into what the issue could be would be great thank you. (Audi a3 2.0tfsi 09 fwd)
