mine does it to, what you will find is threes a little stick in the indicator stalk that catches a little groove in the steering wheel column, now what you will find is you might have broken off a small amount of the little catcher probably only 1-2mm off the end usual wear & tear i find mine kinda moves but not enough to flick it back, i was simply going to bend the eges of the hole out a bit so it catches a bit better next time i had the steering wheel shroud off. have a look and let us know what you discover & maybe post some pic's if you fix it by just bending the edges of the hole out
