Yup this is the noise mine makes. It also makes it going over bumps too without accelerating. It's almost liek a metal flex of the protective metal shield or something.
I have something similar. To me i can feel clunk in the pedal and I can feel it in the steering wheel. It feels like the motor mount is bouncing around or something. I have an audible creak over bumps too.
may be similar or something different on what I have.
