One year old Macan 4 with manual charger flap doors. Few months back the passenger side charge flap door stopped opening. Tech at Porsche showed me how to take the external (painted) flap off, reveal the mechanism inside and slide it to lock/unlock.
Good to know this for an emergency. They replaced the actuator and that fixed the issue. Few months later the same issue started happening on the driver side charge flap as well. Getting that actuator also replaced.
