There is this whining noise coming out from my engine bay. The noise only emits when the car is in gear and when its ON or when the engine is started. I do not hear the sound in ACC mode. When the car is not in gear, the sound goes away. Is this normal? Any ideas what could be making that noise? I have taken a video of it. Link is posted below.
I have read other threads in here that mentioned a similar high frequency whine. But not sure if its the exact same sound, since I do not hear it in the cabin due to the engine drowning out the noise.
