I have borrowed a Nissan Leaf for a fortnight and i have to be honest i have been very impressed so far. However, tonight when i have gone to charge the car the three blue lights to the front are flashing together and the car is making a beeping noise. I have contacted charge master but they have said that they have never heard of this before and have advised that they will ring me back on Monday as there is nothing they can do over the weekend. I have looked through the forum but could not see this exact fault. Worrying that i have broken something so would really appreciate a bit of help and guidance. Thank you in advance, Sam.
