    That’s why I was asking if it was very warm where you are, if battery pack temps are very high during charging Zoe can use aircon to cool the pack, during moderate temps it will just use the fans in the pack.

    This is where Zoe outdoes the Leaf as they are prone to overheating packs due to lack of active cooling.

    Update….
    Hope this may help others…Renault Garage just rang me and said they need to order a new “compressor pump for the aircon”? on mine. Im hoping my noise will be banished after this replacement. Also hope this news will help others in future if they hear the same noise. The mechanic said he had never ever heard one sound like ours. My only annoyance is the car was bought Saturday and the service book is ticked but i have three problems: the noise, wheel balancing out at 60mph and aircon doesnt get cold. What are they actually checking when servicing these cars if they missed three things, cant all have developed as faults since Saturday… not good start with my Renault relationship 😁

    Played video through my hifi, and think you could sell it to a wrapper? All I hear is load clicking and a voice, could it be the sound of something winding up?
    Still having polar home charging problems here, which involves a noise coming from the car charging socket during attempted charging.This noise is a cross between a chattering relay, and arching. OPity the contacts are not copper, but cheap aluminum.
    Certainly the only noises I hear on driving Zoe, are the pedestrian warning noise under 20 mph, and the heat pump, / heater/ air-conditioning.

    The noise and non working aircon are almost certainly related.

    @reboot – I recently fixed Trevor’s Polar charger which had high contact resistance on the relay driving the contactors, causing them to chatter and overheat, eventually welding themselves shut (i.e. permanently live!). I replaced the relay, contactor, and incorrect capacitors (not related to relay fault).

    Is your car OK on another charger? Can you try another car on your charger?

    Sorry to resurrect… I have a similar issue. My Zoe has just had it’s fan assembly replaced (5 months old) and when charging I now get a shorting sound… does anyone have any ideas… the tech thinks it’s normal, but it is coming from the BCB which isn’t cooled???

    The high pitch whine is normal, but it is the arching / shorting sound that worries me!

    The BCB is giving the following error codes. Dealer says it is normal… not really buying it!
