Grinding noises in the engine compartment

It’s about my Seat Leon, which I bought recently. Recently noises appear, see video. Can that be the timing belt? Some others tap on the hydropunch in the block. That would be a heavy bill for me. Someone already had such a noise? Seat Leon 2.0 FSI 2006 year of construction and 150 hp.https://youtu.be/DpMtV83i494 PS: I used the SuFu, but did not find any concrete details about my problem.
