BMW and mini indicators work the same I think?
when I drive the daughters mini, like my Vw
, I use the comfort indicators so just quickly depress the indicator and it will flash them 3 times then stop on its own,
or push the stalk past the resistance point and hold it there, it will keep indicating until you let go.
or press the stalk past the resistance till the indicator stays on all the time to cancel press the stalk the opposite direction use was once lightly and it will cancel.
It takes a little getting used to so practice when parked up.
