Hello all,
I'm coming to you for help with my MG ZS EV 2022 luxury (long-range battery). I've bought the car in June 2023 pretty much brand-new from a dealer and I've had trouble charging it from the beginning.
What I normally do is, I drive up to a charger, I turn the car off, then press the start button twice without pushing the brake pedal, so that the car is "on" but not in "drive mode". I then connect the charging cable, first to the charger, then to the car. I make sure the cable is pushed in all the way on both places, the charger and the car.
I then unlock the charger, whether with an app, RFID chip, of if I'm lucky just with a contactless credit card. In about 1% of cases the car connects and starts charging on the first go. In almost every case the car says "Connecting" for a good 2 minutes until it eventually says "Electrical grid abnormal". I then get out of the car, disconnect and reconnect the cable, and try again. Usually it works on the 3rd go or so. I've noticed it's worse in winter, which, here in Norway, is a problem. While this is incredibly annoying, I've not cared too much about it until recently, when I was about 400km from home and could not get the car to charge at all at 4 different chargers. I was fiddeling with this for over 20 minutes and could not get the car connected. I tried 4 different chargers that were available, no such luck. I thought I'd have to get the car towed but ended up driving to a different location where it eventually connected.
To be clear, this happens with everything from 1-phase slow chargers to 150kw fast-chargers.
I've got a good hour of "video evidence" of the car just not charging and I've had the car back at the dealership 3 times now. Each time they tell me they cannot find a fault and it connects every time for them. Last time they updated the car's firmware to no avail. I've offered to drive the mechanic to any public charger so he can see with his own eyes that it's not working. He says even if he did come with me, it wouldn't matter because he can't read out any error codes when the car is away from the garage.
I bought myself an OBD2 bluetooth dongle (OBD2 ELM327 V1.5) to maybe read out the error code myself, but the dongle won't connect to the car properly. It connects to the ELM but not to the ECU.
Do any of you have any good advise?
I'm grateful for anything that can help me with this.
Thanks in advance,
Stefan

- I'm thinking I can bring the car to another mechanic. Maybe it will show the same issue at their chargers?
- Do you know of any OBD dongle that works for this model?
- Can I use the MG iSmart app to read error codes?
- Is there something else I can try or I am doing wrong? I read on here that some people turn the car off, connect the charger and then turn the car back on. Is that what everybody is doing?
I'm grateful for anything that can help me with this.
Thanks in advance,

But that's probably because I need an OBD dongle that's MG compatible. Any thoughts there?
I'll try this and will let you know. I'm not sure when I will be able to try this - it might take me a few days.
