Yea same, sounds tapety. But its totally normal on these. Like you said, as if the oil is very low.

yea mine does exactly the same, more like ticking rather than tapping and it changes speed with the engine.  Dont think its anything serious because mines always done it and ive seen other people talking about it on here.  Nothing to worry about mate

i kept a clackery clockery (technical term) noise like that.  Started about 30 secs after starting the car.  Turns out it was that.
