Huhu ?? I’ve had the new Clio IV since Thursday. There’s a parking aid in the back, which also worked in the car dealership (set the tone on reverse gear, etc.) So when I drove today and inserted the reverse gear, there was no sound, not even with an obstacle. So no sound at all. There’s also no message in the BC. Since I don’t have a switch for the parking aid, it can’t be disabled either. What could that be? Will call in the car dealership tomorrow, l Is yes under the guarantee ??
