Thought I'd share this experience... I've got the Tesla update and have successfully charged at various Tesla stations. On the way back from Cornwall my navigator used google maps to direct me to what I thought was Tesla Service Centre, Exeter but in reality I was taken to Tesla Moto Services, Exeter - which isn't open to non-Tesla drivers. Not realising this, I plugged in the CCS and of course the car wouldn't charge. BUT when I went to start up I got an 'HV Battery Fault' warning on the dash and the car refused to move. I tried to clear the alleged fault by turning off and locking the car several times without success and I concluded - rightly or wrongly - that Tesla had crashed my beloved car's computer(s). Luckily I remembered that elsewhere on this forum it was mentioned that the car could be forced to reboot by disconnecting the 12v battery. So I did just that and hey presto the car then came back to life and I was able to reverse out and drive to Tesla Darts Farm, Exeter to get charged.
