Electrical Noise

EE60 · 04-05-2020, 04:57 PM

I took my 235i out for a Covid-19 cruise to nowhere today.

Strange thing. Before I started out I heard what sounded like an electrical motor cycle on and off behind me and to the left. Like it was coming from the driver's rear wheel area. I wasn't the seat motor, but it sounded like it. Any thoughts? Could it be something related to the adaptive suspension?

Thank you

High pressure fuel pump ?

More likely low-pressure fuel pump.
