I had this problem with my c300 every now and again. After I let go of the brakes from a red light, there is a noise coming and it sounds like it's coming from the steering. I completely let go of the brakes and even if I don't turn the wheel, you can still hear it. Only when I'm going slow. I don't think it's the brakes and I've taken it to the dealership twice but every time it's something that could be covered under the warranty, they never seem to find the problem. They always say they don't hear the noise, I've tried to record but you can't hear it. The noise is almost like the noise that comes from the brakes but it seems as something is rusty. ANy help

I'm not 100% sure I understand the noise you hear but I will point out that something called the e-brake boot can need replacement on C63's, not sure if they're the same on the C300's. But, in cold weather they squeek a very high pitch. It doesn't happen often but it's loud and annoying.

Might be that. Its not always but it is very high pitched and annoying. Ill run that by the dealership and see what they say.
