GLA 220d high pitch whine noise

Hi All,

I've just taken purchase of a 2016 GLA 220d AMG Line 4 matic. I've noticed a high pitching whining noise, which is pretty much constant when the engine is running. I tried turning on and off just about every button/gadget/heater to try and eliminate and I've managed to pinpoint the noise coming from the drivers footwell, which I suppose probably means from the engine bay? It only starts when the engine starts so I'm guessing maybe fuel pump or a belt? Any advice would be helpful. Thanks
