I am having a weird issue on my R57 where I can hear an electrical buzzing as soon as i turn the ignition on, it gets louder if i turn the lights on or press the brake pedal. I can also hear a whining that climbs with engine RPM.

I have checked the battery earth, as well as the earth strap in the engine bay, and under the valve cover and they are all fine.

Has anyone had the issue before and know of a fix? As far as I am aware the speakers are stock.
