BMW e46 320D 150 Hp 4/2004 acceleration issue

hello mates. i have a problem with my BMW (e46 320D 150hp from 4/2004) and i hope i'll find a solution here. sometimes while driving i have encoutred a strange problem, when i tried to run the car with full acceleration the car wasn't going as aspected, like there was no torque anymore and remain blocked around 2200 RPM and 11 l/100km. after i released the acceleration pedal and pressed again the RPM indicator decresed and after that increased back to the previous position same with the consumption indicator which came back to 11 l/100km. i've tried to switch the gear but same problem at a different RMP but same instant consumption indication about 11 l/100km. after a few seconds everything becomes normal and the car starts to perform normal. i repeat this problem is not always present and i have no ideea what is it about, what is causing it. all this cand take about 1-2 minute maximum 5minutes and then everyting is normal. i have a video maybe it helps to understand much better the problem.



thanks and i hope there is somenone who cand help me.
