M57 Rumbling noise inside the car

Hello, i have e91 2009 M57 325d automatic, there is a rumbling loud noise inside the car, sometimes dashboard vibrations. It is reflected in the idling speed of the engine approximately to 1000rpm. it's worse when it's cold.

I replaced engine and gearbox mounts (febi bilstein), but it sounds the same.

Here is video - https://www.youtube.com/shorts/JpLM9Tj3AsM

injector test in the attachment

any solution?

Injectors look fine. Remove the serp belt and run the engine, vibration still there?
