I have a 2007 Speed3 that I have had for about a month now with 1000 kms on it. Under hard acceleration on bumpy roads I have noticed that there is a loud bang that seems to be from the left front of the car. It kind of sounds like the front suspension is hitting hard and compacting the shocks completly. Is this bang normal or could it even possibly be a problem with a motor mount? I know there is a recall on the #4 mount. When this mount blows is it quite noticable ie. heavy vibrations or a little more subtle and more like what I am experienceing.. I called my dealer, they were VERY helpful......................
