Weird noise

Hello, I have Audi A3 (2014) 2.0tdi 150hp (CRLB engine) 155k km(96k miles) on clock, and there is a problem that you can hear in video below, when I start accelerating I can hear this noise from 1500-2000rpm and after that is silent, and this happens on warm engine only. Noise is coming from left side of turbocharger. Air filter is changed, oil changed, no oil missing, acceleration is normal, no smoke from exhaust, no engine codes or anything. Is my turbocharger going bad or there is a vacuum leak somewhere? I will try to do vacuum leak test today
