So I had the BMS update done along with the first service last week and have just fully charged, forgot to reset to see what I actually get, but I will reset it now (after ~ 6 miles) and see how it goes, granted some of the last charge was used just driving locally which has improved m/kWh.

Just booked my Zoe 50 in for it's first service next week. Things did not go well when the service desk person told me that the fix I had been emailed about shortly after purchase was just a software update. I told her it specifically said the car needed a new CPU to enable remote activation via the app. She then stated that the information they had was in French and then eventually agreed that it listed a part no, so yes it did involve a hardware change. We then discussed the ACTIS numbers I wanted them to apply, mainly the BMS update as the range had dropped by 10% in less than a year. She noted this and I asked her to check with the EV specialist. I got called back an hour later to be told that the ACTIS number I had given was not related to the CPU change. I agreed and restated that it was because the range had fallen. The answer was that this would only be addressed as a result of a complaint. So I made a complaint. I came away from the conversation convinced that not a lot is going to get updated when I take it in. Let's hope I'm wrong.

Sourced myself a dongle and had a look at the CanZE app today. Had to use the iOS beta as I don't have an android device.

Couldn't find the exact screen posted earlier but this one seems to suggest a SOH of 92%. This seems a bit low? Manufactured in 2020 with only 6k miles on the clock.

Today I took the Zoe in for its first service.

I had asked for them to:

1) Carry out the first A service (12 months and 5500 miles)
2) Replace the CPU as detailed in the recall email I received last October which stated -

Our tech team have been working hard to identify the issue with some of the connected features between the MY Renault App and ZOE.

The good news is that a fix has been found to allow remote activation of pre-conditioning of your ZOE from the MY Renault App.

The Tech bit

The Central Processing Unit (CPU) in your ZOE is not ‘talking’ to the MY Renault App. The CPU, which is located in the passenger compartment of your ZOE, needs to be replaced. Your local Renault dealer will be able to replace the CPU for you in less than an hour and of course completely free of charge.



3) Fix the issue with fully maximimum range showing as only 210, even after a reset.

They did 1)

On 2) I'm not sure what they did. They didn't seem to know anything about the CPU change described in the email even though I had gone through the email at length with the person who booked the car in. However, they told me that the 'BCM has been replaced and reprogrammed as part of a product update and this can improve range - reset and customer to monitor'. Does anyone know if this is the same as the CPU? Regardless, checking the battery percentage against predicted range still shows a maximum of 210 miles. If I fully charge and reset should I expect to see an increase?

On 3) I was told 'Investigated reported range issue - No Actis solutions or updates available. Checked and no faults stoted (stored?). I had given the receptionist a list of the Actis numbers listed on this website as fixing the range issue, but clearly none of these had been applied.

I didn't want to be confrontational as I was cross and it had been a long day. We live an hour away and dropped it off at 0900 as requested to be told it would be ready at 1600. They told me they would try and get it done earlier, but having little faith in them we drove back home so the day wouldn't be totally wasted. On the way back to pick it up I got a call at 1530 to say work had been delayed and they had just started working on it. At 1630 I got another call to say it was ready. It appears that I have paid £118 to have the car washed and the pollen filter changed.... On the plus side, the service report gave a green light to items such as engine oil level, fuel system and cambelt.

Can anyone advise me if the BCM is the same as the CPU and any other thoughts on the above?

The service report also stated that I would get a follow up email from Renault, who would be expecting them to get 10/10 and to make them aware if I intended scoring something else. I'm thinking about 2 or 3 on what I saw today

Cheers

The CPU, as defined in Renault's email, is definitely not the BMS (the battery management system). It is the processor running the user interface and communicating back to Renault.

OK, so something has worked. I now get a notification when the car starts and stops charging and I can remotely change the preconditioning. Hurray. However, the the range issue remains. I charged to 100% overnight and reset using the ok button on the stalk. The maximum range shown is 220miles which is about 8.5% loss of range in 12 months. I have read about a 2 pedal reset. I have tried holding both pedals down while turning the car on and also while resetting the trip with the OK button. This has made no difference. Can anyone confirm how the 2 pedal reset is done on the 50?

So, I've just taken my ZE50 into Renault Telford for the 1st year service and asked them to apply ACTIS 64453, which I believe carries out the BMS update. The SOH has been varying between 92% and 96% over the last 6 months and the car has only done about 6,000 miles due to Covid. My notes, from various threads and forums, say that the ACTIS should update the following:

LBC: from 521 or 530 to 543.
LBC2: to 521 or 530 to 543.
EVC: to 69B0.
BCB: to 0A40.

Renault Telford tell me that the ACTIS has been applied, but CanZE tells me that the LBC and LBC2 are at 530 (which I'm fairly certain is what they were at before the service). The SOH is showing as 94%, so no improvement there.

I suspect the updates have not been applied. Can anyone confirm that the above is correct please?
