E90 335xi 2008 knock

I just bought an e90 and after driving it for 2 days it started making a knocking noise after is warmed up and when you rev it past 2k rpm and maintain the throttle or when you accelerate and then let go. I have changed the turbos, injectors, spark plugs and coils.

Does anyone know what the knocking could be?(not the wastegate rattle, I already fixed that)
