Hey, new here. My Zoe heater stopped working recently. The aircon still works fine and is extremely cold. The system was regassed recently. And ideas why the cold would work but not the hot?
Checked for cause of aircon not working, Checked gas pressure all ok, Carried out Clip check on EVC computer, found EVC computer not configured to have aircon, Carried out reconfiguration of EVC computer and tested all ok
just an update the heater also works if F3 fuse is pulledyou can hear 3 relays click in if the heater deployed, which heater working, as there is a heat pump heater and aux heater.
with AC OFF/ON still pulls 1Kw of power as displayed in picture.
The Zoe uses the new 1234yf AC gas and it is a lot more expensive than the previous gas. A re-gas can cost the best part of £200 did you pay around that amount?
Halfords can only regas, not diagnose or fix a/c faults.
You will need a Renault Garage or HEVRA Garage such as Cleevely EV to actually diagnose & fix this as you have said you have done all the basic checks including hair dyer on
Thanks yes fair enough, I will be taking it to Renault, I'm just trying to get a sense of what's wrong in advance as they don't seem to have the slightest clue about EVs. Halfords was just to do a regas, at that point I just thought the gas was low. Appreciate all your help!
Yes the heating worked fine before the regas. I took it for regas because the aircon had stopped being cold. They said the gas level was not that low and topped it up. After that the cold worked but not the hot.
thanks, I'm hoping it's a software issue as when the mechanic OBD reader witha system fault code: DF082 Inverter Fan Assembly Activeill keep you posted in on the 15th for a repair.
Update after Auto car engineer done some investigation
Climate ECU shows 51 Bar for reference system pressure,
EV control unit shows correct system pressure 5 bar
software update to correct above.
Booked in on the 15th April for software update
ill post outcome after

Did Heat work OK BEFORE the Regas?
What is the Ambient Temperature and What is the Air Vent Temperature?
You don't have ECO mode selected do you?
