well i noticed sometimes like when coming to a stop, then rpms drop for a split second and a clunking noise occurs, then the rpms go back up

also happens when i shut the car off and turn the ignition back on right away

i think it happens if the car is idling and you turn the wheel a lot too

anyone know anything about it? is something wrong or is it normal

maybe something to do with vaccuum?

Normal, every 6er i've driven does it, so do the GT's, and many other vehicles.

alright good
