Its hard sometimes to notice sounds that aren't right in videos. But to me it just sounds like the injectors/high pressure fuel pump. Is it the same during both cold and warm engine operation? What area is it loudest in? Engine bay, under car, in car?
Durring both, cold and warm. I notice it more close to wall. But it sounds like its inside the engine, when I open the hood its louder. It almost sounds like metal clicking
