r/RenaultZoe

Hello, I have a Renault Zoe Intense R110 (2015) which has 110K KMs with a rental battery. For over a year now it has been parked in my parking lot after intermittently not charging (it would stop spontaneously) and finally dripping water onto the pedals if I drove it after it rained or left it charging while raining. Then came the dreaded "electrical fault DANGER" message. Now I ordered an OBD2 adapter in order to diagnose it but the issue is it doesn't start up anymore. Long story short, I just wanna know just how much this would cost to repair, if it's something I can diagnose on my own considering it won't start up, and how I can do so. Thank you all for your help and I'm sorry if I am ignorant on the matter, i am very new to this.

I have left my Konnwei KW902 ELM327 reader plugged in my ZE50. But I have travelled from home for a week.

Is it a problem? Will that drain the battery?

Hi,

Need some advice, buying a used zoe 2020 model R135 with 19K miles mileage. Asked for a SOH and it came out today with 84.2%. Is it too low or the right ballpark?

Thanks

Hey there,

I own a first generation Zoe Q210 from 2013, almost 200k km and still going. I bought it in 2020 and range was good with 130km in summer and around 90km in winter which I was happy with. This was also matching what I saw on the totals for charging and distance driven.

In spring 2025 I noticed that range wasn't going back up as usual. It was at 110km max which was still fine but not what I was expecting. For winter 25/26, range was ok at 85km. But this year it looks like it will not even get back up from the winter range.

First thought obviously, the battery is dying. Interestingly though, when I drive the car for a certain distance and park it, the range will go back up, sometimes as much as 20km. Last week for example there was the following situation:

Start at 80km range, drove 22.5km -> remaining range shows 50km
2 hours break -> range is back up to 70km
Same route back -> remaining range was at 40km
A couple hours later in the evening when I had another look it was back up at 50.

So overall, I get more range than initially shown and range is effectively >100km, but the display value is behaving quite strange.

Resetting drive stats will make it show 130km range for a short time, but that will quickly go back to the 85km we now typically see after charging.

I also had a look at CanZE, here are some numbers:

Usable charge: 98.4%
Real charge: 92.9%
Available energy: 18.5 kWh (I've seen 19.5kWh here recently when it is fully charged)
Voltage: 394V
SoH: 84%
Range: 84km

I read about some calculation bug in the software, my LBC has version 0854 and as far as I understood this bug should be fixed. Voltage difference between cells when the car is not moving is around 10-30mV which I think should be fine as well.

I then started the car and drove around and noticed that cells are starting to act weird when I accelerate. Voltage differences jumps up to 100+mV and I can see cells 1-62 being at the lower end of the difference and all the other cells being at the upper end (3.88V vs 3.99V). When I let go of the pedal and recuperation kicks in, this turns around (4.02V vs 3.92V).

My guess now is that one of the cells is acting up and the balancing is trying to fix it which seems to partly work.

Has anyone had similar experiences? If so, have you been able to find any solutions to this or is it time for a new car? I'd love to keep it if possible, I'm really happy with it overall.

Hi, thanks for taking the time to read this. my air-con definitely dosnt work right, its definitely full of gas and doesn't have any leaks. If i use recirc it gets hotter . If it’s above 25c it’s basically useless. Any help and ideas would be highly appreciated, thanks

It’s a 2021 Renault Zoe

Has anyone got any experience if these Australian dashboard covers for the Zoe? Worth getting? I was toying with making one as theres nothing available in the UK I can find.
