N20 Heater control valve.
Hi. Is this noise and pulsation caused by the heater control valve? I notice it especially on hybrid mode. Noise/movement comes when fan is on and temperature is set to low but goes away when on high. Also when I turn off the car the noise persists until it seems to time out.
In the video you can also see the heater control valve. I don’t think its the auxiliary water pump because the pulsation/noise goes away when heat setting is on max/high. Video is taken near the coolant reservoir where the heater control valve is located.
No error codes.

Thanks in advance.
