May Be A Silly Question (Humming Noise)

I havent had my 320d long and been doing little jobs on it like the swirl blanks and crankcase filter, but this noise may of been there before but i havent noticed it lol.

Its when you switch the ignition on, there appears to be something running / humming for about 20 ish seconds then stops, it happens everytime i switch the ignition on. Air con / fan is off.

Could it be the fuel pump? Any ideas or do i need to make sure the radio is on lol :)

Thanks

    Jumping to conclusions, the first thing I would say is... Fuel Pump (A healthy noise to hear)

    Gav will get back to you with a defo on that one. If it is something else, no doubt we can help bud
