Buzzing sound from ABS pump assy
Hi friends. I’ve been hearing a constant annoying buzzing sound when I turn the ignition on. I localized there sound next to the engine, ABS pump assy. I’m including the video.
can you please tell me why it’s doing it and what I can do to fix it? Thank you!

Hi, sorry for the late reply. I just showed the car to a mechanic and he pointed to the water pump. The water pump makes that weird squealing, buzzing sound.
About the ignition: I meant that when I simply turn the key without starting the engine..

The noise that you are hearing is the activation of the Coolant Circ. Pump which is normal and has nothing to do with a faulty Water Pump.
