Bmw 118i Engine N46B20 Strange knock sounds from the Engine bay in RPM range 2k-3k

[Aleksand]

Hi, Guys !
I'm owner of BMW 118i N46B20 Enginge. Before two months I've heard a strange noise from the Engine bay and I decided to check with ISTA diagnostic.
ISTA shows me error code for bad knock sensor (DME 002E68 Knock-sensor signal 1). I've replaced the sensor and delete the error code, but this doesn't resolve the problem.
The knocking sounds are between 2k and 3k RPM only.
I've created a video here is the link - https://youtu.be/cnrOBSTH4Sc
I will be very appreciated if someone can help me to investigate and resolve the issue.
