Hello Everyone!

Today, when I drive into my Garage, I've heard a strange noise from my engine.

I think, that I've haven't heared it before. Is it normal or not?

I hear this strange noise from the left part of the engine.
Its like something is clattering, maybe it is Hydro compensator's, or something else.
When I increase RPM, sound increase in speed too.

I've record it into my phone, 15 second, you can hear clattering in my recording.

If you have time, please hear it and if you have something to say, I would be very glad.
(Its in AMR).

I'm now at 37 000 km.
