BMW M5 F10 Strange sound at gear 3,4,6

[Weekiat21]

Hi All,
I'm experiencing an issue. I have these strange sound coming out from the dashboard whenever i accelerate from gear 3,4 and 6th.
Gear 1,2,5 and 7th have no sound.

All 8 fuel injectors, spark plugs and ignition coils have changed.
Noise still persists. Has anyone encounter before?
