I have brought my car to the dealership twice for this problem and they have not been any help. My X5(non-sport) makes a clunking noise when I press the brakes. The noise is from the left front and it is more from the momentum of the car going forward as opposed to the brakes being depressed(if you understand what i am saying). So if i just quickly depress the brakes the car rocks forward causing the clunk. With the windows down it is failrly loud. Also has anyone done any DIY suspension work to there e70?
