So my R56 has 63k on it and lately ive been hearing 1:a rattling coming from somewhere in the engine bay while driving at low speeds going around corners usually in 2nd. It sounds like metal on plastic bit im not sure. And 2: when at about 50mph and up when I barely have my foor on the gas I hear a somewhat high pitch whineing noise, when I release the gas it stops. Any clues would be great the car still drives normally.
