What you are hearing is ground loop interference. If you have an aftermarket headunit/amplifier this is a common occurrence. A ground loop isolator in line with the low level amplifier inputs should solve the problem. Otherwise, it may be a malfunction of the stock cd unit or amplifier. BMW used a balanced input on some of the stock amplifiers, which would make ground loop interference all but impossible.
