I know that the DU noises have been talked about as nauseum here and I read through most of the pages but didn't see my noise. (I tried to upload a short video I took but I can't get it to upload) anyhow when depressing the accelerator and letting off there is a loud clicking sound almost like gears changing on a bicycle. I sent the video to my SC and they said it's a rock BUT how does a rock get inside an enclosed unit? And it only makes this noise when pressing or letting off on the accelerator. If anyone can tell me how to upload my video id be happy to do it. Many question has anyone else heard something similar? I'm taking it in next week but have a planned trip this weekend and now am a bit worried to be so far from my SC.
