Southern tee Posted April 27, 2022 Share Posted April 27, 2022 I have recently got a B max 2013/25k miles. It has a noise like an electric motor. Turn ignition on it starts the stops abruptly. Start up it hums annoyingly all the time. Audible in cab, less so from outside. Seems to be behind driver, low down and left. Anyone any clues.

unofix Posted April 27, 2022 Share Posted April 27, 2022 It is probably the electric fuel pump pressurising the system. You can hear them on many vehicles, but some make more noise than others. Yours might just be getting ready to fail. Quote Link to comment Share on other sites More sharing options...
