Kezo can you please confirm but it looks to me that the megane techno and the MG4 don’t have electric folding mirrors when you lock the car ?!
On the Trophy spec “Electrically adjustable power folding heated black door mirrors” SE doesn’t mention auto folding!

Megane not sure at mo, Maybe someone who has one can say! (older ones were operated from a knob to fold)
