Hey i have a 2000 a4 2.8 quattro which is manuel. lately i have noticed that when i am at a light and start to roll less t a very dull noise comes from where my accelerator pedal is and i have almost feel something when my foot is on it. it sounds as if it is something that is rotating in that area. sometimes is gets somewhat loud but i cant figure out what it could be. any help would be great thanks

 

I dont understand....
