Yep, reset it several times. Sometimes it works and sometimes it doesn’t. Problem is definitely with the car and not the charge point because the car’s charge port locking pin activates and prevents you from plugging the car in (or releasing the cable if already plugged in).
Booked in to a service centre for mid Feb (earliest they could accommodate me) but the problem is now occurring so frequently that it won’t be long before I get properly stranded given the miles I have to do for work!
