    Just outside of warranty and with just 30k miles on the clock, out Zoe has lost all it’s air con gas due to a seal failure and after a re-gas the Renault main dealer tells us that the compressor has failed.
    £899 to fix it. Renault customer service admit that it is a manufacturing defect that this unit has failed but only offered 1 hour off the cost of the labour to fix this.
    In all my years of driving (40 to be precise) I have never had a compressor failure on any car and to have this fail just a couple of months outside the warranty and with only 30k miles is really disappointing.
    We can manage quite happily without aircon but clearly the battery can’t so what happens if we choose not to blow that money on getting the air con fixed? Will the battery go into meltdown or just reduce output?
    Does an air con issue leave you with an un-drive-able car?
    There are loads of conventional cars running about with air con that doesn’t work or in need of gassing so where does that leave us?
    Personally, I think that Renault should stand by their product and cover this, or have there been too many failures already but not enough to recall any cars?

    I have not heard of many issues on the ZOE with the air-con, so I don’t think it’s widespread. Mine went 48k miles without aircon failure.

    I’m not sure the aircon is used directly to cool the battery, since the ZOE has a water cooled battery with fans. I suspect – though don’t know for sure – that your battery life will be largely unaffected.



    VERY common part they fails and causes gas to leak, sorry to see you aint picked up on it while under warranty.

    no air con results in NO HEATING, NO COOLING and most importantly no battery cooling.

    I have just replaced the air con/heat pump on my 63 plate Zoe with 42,000 miles up. The unit started to get noisy but before I was able to have it checked it suffered a short/earth and this resulted in the whole electrical system shutting down and the car refusing to start. Flat bed to the nearest dealer (55 miles away) and diagnosed as aircon failure. £844 +VAT for a new unit plus labour. I had the front discs and pads renewed at the same time so the bottom line was £2K. The dealer was unwilling to ask Renault for any goodwill and I’m pleased I did not bother if the best they could offer is 1 hour labour. Car has run well since the repairs and the heater is no better or worse which suggests that it was not short of gas at the time of the failure and the cause was mechanical rather than loss of gas.

    The car had been no real bother so far and despite this hefty expense, I am still pleased with it, but I would advise Andyt1320 to get his AC fixed before the car does become undriveable



    I’ve seen a Zoe today with the battery removed and it’s definitely air cooled. The water cooling system is for the motor, not the battery. I’m pretty sure that if the aircon isn’t working then the battery won’t be properly cooled.
