E46 Coupe Knocking Noise From Front O/s When Changing. Gears

[joykiller]

325ci, took a bend a bit too fast the other day, ever since ive had a knocking noise(sounds like its coming from the drivers side footwell or that area)it happens everytime i change gears and more recently over bumps,been underneath cant find anything untoward, can anybody please help its driving me mental,had it checked by 2 mechanics who couldnt find the source,please, please help

Could be the suspension arm rear ( lollipop ) bush that's gone, best thing is drop into a garage for a check up. Oh & its easier to change the whole arm than just the bush.

Thanks, will direct the grease monkey in that area

Just to add,it only does it when changing up through the gears not down,very occasionally over bumps,but not always,and sometimes sounds like its coming from the sill on the side,any ideas??
