I have posted something similar on another forum, so apologies if anyone is already aware of this problem.

Not being a high mileage user, it wasn't until mid September that I needed to charge my car at home on my EO Mini Pro2. When I tried, I kept getting error messages and the light in the car's charge port turned red. I rang EO support to get some help. Anyway, to cut a long story short, it would appear that after the 12v battery swap and v2.4 software update, there appears to be a problem with my EO charger talking to the car. Since first reporting the problem, EO have been in contact with VW in Germany, who recognise there is a problem and are now working with them on a solution.
Although inconvenient, I have been able to charge my car at Tesco on one of their 7kWh chargers and also on a granny plug charger at home.

No such problem with Wallbox Pulsar Plus, so maybe the issue is with EO? (ID.4 with V2.4 update and 12V battery swap)

Hope it gets resolved soon for all EO customers.

I've just been called by VW Dealership and 2.4 has been stopped for rollout again and 3.0 updates are suspended for OTA because of other problems- I'm stuck on 2.4 and half charging with EO Mini Pro 2.

Why did the VW dealership call you if you already have 2.4, just in response to your EO issues you’d raised?

3.0 OTA is about to be trialled in the UK and other EU countries, and the learning from that will feed into the full rollout shortly after.

That’s my understanding anyway.

 

[chrisnewmanuk]

They called because I have a problem where 2.4 broke the charging - it wont go above 3.7kwh AC at all. I complained to VW directly and had a response today via the dealership. Nothing specific on the EO but they did tell me about the suspension of any more 2.4's and 3.0 wont be coming within the 3-4 weeks that the VW website for 3.0 was saying.
The VW 3.0 site said 7 days from 2.4, after it checked in, 3.0 would start downloading - my 2.4 was installed 2 weeks ago after a pause because of suspected 2.4 problems and the 12v temporary shortage.

I mentioned this over in the ID.3 forum, but I had the same issue with my EO Mini Pro 2 charging at half speed the first time I tried to charge after having 2.4 installed on my ID.3. This was with the EO charger starting the charge at 20:30 for Octopus Go Faster. Going outside and unplugging it and plugging it back in put it back up to full speed.

It has since been working at full speed even when the charger has started the charge.

Maybe not much help, but it may resolve itself at some point. Equally I may experience the issue again at some point.

My car won’t remember the charge location since 2.4, so won’t run with my charge timers.

Fortunately, my wallbox pulsar plus can be set to charge off peak, and the car charges happily during that 7 hour economy 7 period.

2.4 is paused at some dealerships as they can’t get hold of the 2.4 12v batteries which are on back order.

3.0 OTA is about to enter a trial phase across the EU, that was on the VW firstmovers Facebook page a week or so ago.

What a dealership tells you is always worth checking before assuming it’s gospel.

Update: Since my original post, I contacted VW Customer Support as well as EO. Then, last week, VW contacted me to say they were going to talk with my dealer (Listers Evesham). Anyway, on Monday, Listers rang and one of their technicians arranged to come over to my house on Wednesday. First of all he tried a new charging cable. This worked. He then tried my cable which also worked. Previous to this, I had tried numerous suggestions from EO, none of which worked. What has happened, you tell me. All of a sudden all working again! I emailed EO to ask if they had rolled out an over the air fix to my charger, but as yet, no reply.

 

[roadhawk]

I've both an ID.3 and ID.4 and an EO Mini Pro 2. Both cars are on 2.4 and are able to charge ok. I use timed charging setup on the EO (Go Faster 5 hours from 8:30pm->1:30pm). My EO is non-tethered. A couple of times since 2.4 the cars have started charging at half the normal rate (3.6kwh?). If they do I stop the charging on the WeConnectID app and restart and it comes up at the full 7kwh rate.

Perhaps getting it working with the other cable was enough to cause the EO to reset?

 

[hez]

It definitely seems a bit random and is all to do with the timed charging being set on the EO unit. Mine as noted above charged at half rate the first time I charged after 2.4, but since then has been fine. The one time it did start at half rate, unplugging and plugging back in kicked it up to full speed.

However, last night it charged at half rate again. Annoyingly I didn't check at 20:30 when it would have kicked in as it had been fine the last few times. But woke up this morning to just over 30% being added to the car over 5 hours.

 

[hez]

Happened again last night, started half rate at 20:30. Did as suggested and stopped and started it from the app and it went back to full speed.

Bit frustrating, but not a massive deal given the start time. Would be more of an issue on normal Octopus Go if already in bed when the charge starts.

Update: I did manage to get in touch with EO eventually and they advised me that there was an update in the pipeline, but it hadn't been rolled out yet, so still a mystery.

 

[hez]

I had the following email today from EO following me logging the issue with them. Some of it is a bit above me in terms of my knowledge, but it at least shows they know what the issue is and are attempting to fix it:

"Here is more information about this issue. I can confirm some things with you, firstly the issue you are experiencing is happening across the whole VAG group so Audi, VW, Skoda etc. This is something that is happening on other charge points as well and identified as a vehicle issue and our R&D team is working with VW technical for a solution. Unfortunately, we are at the mercy of the VAG group in terms of a timeline for a fix for this issue. We currently have 6 Employees all experiencing this issue which we are testing to see if we can implement a workaround.

We had a VW Technician to our HQ recently and they made a report on the issue. I don’t have access to the full report but I do have the case notes for the visit and this is the findings below:

We can now replicate this issue more easily:

Wait for the vehicle to go to sleep – 10min after locking

Plug the vehicle into MP2

Vehicle only charges at 16 amps

Pause the vehicle

Unpause the vehicle

Vehicle charges at 32amps

This impacts all VW vehicles and most of the other VAG group cars and models because of the same EV platform the vehicles use. The VW technician that was on-site running through the testing has confirmed the following:

This is a VW vehicle issue

The charger is in spec

What is the root cause:

When the vehicle starts to charge, it pulls the CP line down to 6V and enters state C2 – the charging state. The MP2 then closes the relays and allows power to flow. The Mini Pro 2 closes the relays within 150ms of entering state C, the vehicle then reacts too slowly to this change and the vehicle's OBI only requests 16A. The relay timings in the charger are well within spec and are there for safety/regulation reasons.

But fear not, we are going to find a solution that works around the vehicle issue and with the findings, we can implement something that is still within spec. I have had a chat with our R&D team and this shouldn’t be too far away but I’m afraid I can’t give you a timeframe for this."

Has anyone heard of an update to resolve this issue yet? I'm still experiencing it on an intermittent basis but probably 70% of nights it pulls 3.5kW but some nights it runs at 7kW.

 

[Warrior]

Not heard of any update, but mine is still working fine after mysteriously starting to work as per my comments in Post #8.

 

[hez]

Yeah I can confirm mine seems to be behaving now too. Not had a slow charge in a while. Not heard any updates though.

Scheduled charging via the car is completely broken in 2.4, it's fixed in 3.0.
Scheduled charging via the charger will only be fixed the charger supplier. Most of those affected by the reduced charging rate issue (Ohme, Podpoint, maybe now EO?) already have a fix in place but you might need to call them up and register your problems before they will apply it to your charger.

Thanks. I have raised a query again with EO (they didn't reply to the one I raised in December). Hopefully they will confirm what is happening. At the moment the behaviour is random e.g. two weeks ago I had several nights at 7kW then last week it ran at 3.5kW but last night at 7kW again. This is what you might expect when it's a timing issue in the sync between car and charger and it makes it hard to know if it's resolved.
Is there some strong evidence that the VW v3.0 fixes it? If it does then that would be fine.

 

[Warrior]

Just to add, my problem wasn't with scheduled charging, it just wouldn't charge.

I haven't heard of as many people having the reduced charge rate issue with 3.0, but at least one person with a Cupra Born (and an Ohme charger) has, so it's not entirely eliminated. It doesn't matter so much though, because if your charger supplier doesn't fix it, you can put the charger in dumb mode and schedule through the car, which I have found very reliable with 3.0. Then it will always work at full rate.
