See this post for the sometimes problematic cable locking mechanism.
Today my 2013 Q210 ZOE was at the dealer for it’s 4 year maintenance. I arrived there a tad low on battery so I asked them if they could please hook it up once they were done with it. No problem of course. Just as I arrived to collect it, I saw the chief mechanic getting in (it was already hooked up), so I walked up to him first. He was a tad nervous and said he had updated the charger firmware and now he noticed it wasn’t charging. I walked around only to hear the somewhat familiar cam wheel “whee whee” noise from the locker mechanism, so I joked: “well, luckily my friend, I do know what is wrong. Hooked the thing up again and all was dandy, though now of course I had to wait a bit to make it home.
Chatting along he told me the locking motor was now a new part number and maybe I wanted to replace it (80-ish euro). I decided to go for it. I have had a few early terminated charge sessions, and like the inner flap hinge, sometimes Renault does not always acknowledge a warranty issue, but they do improve the design over time. I’ll report back on this.
