Hi guys as the heading suggests i have been getting a weird noise from my z4 coupe, it's not worrying me as such I'm just curious. the noise seems to be coming from behind me but when i use something electric like say the indicators the noise goes from a steady hum to an up and down hum as the indicators click on and off, i am guessing possibly the fuel pump? its only really when stationary or driving slowly i can hear it because of the engine noise.
any comments or ideas welcome.
btw i apologize if i have asked this previously and forgot as i have been meaning to but don't think i ever got round to it.
