| feedback?! hi. i'm new to the group. i just bought a used C280 Sport and i love it. only thing is, i noticed that whenever i slow down from high speed (between 60-80 mph) i hear a sound much like the feedback of a microphone when its set too close to a speaker. i tried isolating the situation like if it only happens when i step on the brakes or it only happens when i reach a certain lower speed but to no avail. it just happens. any idea what this is? this is my first mb so i have no idea what this could be. . . |
