I think the home page has changed: 'EV Management' to 'Charging Management'.

Using the HVAC reduces the range as well has high. Speed and acceleration. What driving parameters have you set, eg, Sport, regen 1.

I agree but I should have explained a bit better. If I need to access the car's status / heat it and it does not respond I use the technique of multiple states requests followed by the keyfob lock/unlock option to bring the car out of deep sleep. As regards draining the 12V battery the ongoing...

The trouble with AI is that no data is referenced so you cannot check whether its interpretation/ understanding in context is correct. I heard the word 'hallucination' the other day with respect to AI models in that they always seek to supply an answer and can come up with some odd results.

No problem pre-heating here in Sheffield. Put it on to try to reduce amount of snow on roof/windscreen. Strangely the bonnet and rear window were completely clear with snow piles beneath them. Isn't there a video where the front vents, which I think open when using the HVAC were frozen shut in...

@Joningy, if you are asking whether your dealer is correct or the AI then I believe the AI is correct except, as @siteguru says no-one really knows at what level the HV stops charging the low voltage battery. You may have 2 problems - a parasitic drain and failure of the low voltage battery...

@Pete1w, you may find this attachment more explanatory. Thanks to @stevedee on the MG5S Forum. Just replace S5 with 4 and Carplay with Android Auto as appropriate. Note the WiFi is for Trophy only in the MG4.

The wiki refers you to the appropriate thread: You are likely to see warnings but these should disappear when you put the car into drive and drive a little way. The iSmart app connects to the car via Bluetooth and via a mobile signal, the latter used when the car is out of Bluetooth range. The...

Further to my post above which may still be necessary. I seem to remember that the app can use either Bluetooth or the car's eSim to lock/unlock. Try disabling Bluetooth on your phone and see if you can still lock/unlock. If what I remembered is correct and you are unable to lock/unlock then...

I assume you have used the car before and after trying to get the other functions to work. So the only thing you can do now is to disconnect the 12V negative battery terminal for 10/20 minutes to reboot the software. After you reconnect the battery you need to carry a set up procedure, please...

For clarification, how do you know SC077 was not done before you got the car? If it wasn't done then how do you know it wasn't done at this first service. My Trophy was done at its second (edit) service in April 2025. The update is a Service Campaign and thus my understanding is that it should...

It would appear that other manufacturers have problems with maintaining the 12V battery capacity. Hyundai and Kia have recalls for the Ioniq 5/6 and EV6 to software update/replace the ICCU (Integrated Chargung Control Unit). The part that maintains the 12V battery can fail completely causing...

According to the manual, if there is a fault with the low-voltage battery charging circuit then the car will display a warning symbol. Unless someone has access to the charging circuit and software then finding the fault would be difficult.

According to the MG4 Manual, keeping the 12V battery charged is 'intelligent'.

I'm in Sheffield too and had no problems this morning. I use the keyfob occasionally to wake the car plus trying a status update a couple of times too just to badger the car. Note that sometimes the Servers don't respond one day but do the next. It appears not to be a blanket effect with only...

I've just repeated the second experiment - screening the keyfob with car auto-locking. Again the car locked automatically followed by the car warning the smart key could not be detected. But no alarm sounded when I opened the door. So, @Zdenek, your car is not working the same ways as my car...

I do not know, the update occurred at the car's first service and was combined with other changes, one of which was ACC. See the thread below (not a link).

@Zdenek, Edit to my last post: the back up location is in the arm rest centre console. My car is MY22 Trophy (top specification). Today I tried to recreate your fault. For my first attempt I put the car into Ready mode, placed the keyfob in tinfoil, locked the doors with the inside door...

I believe your car has a fault. You can investigate by putting the car in Ready mode but not driving and then locking the car from the inside. Does the keyfob error show and the alarm sound when you then exit the car? I assume you can power down the car (with the doors locked) from the...

Lights coming on in sunshine and bright days was fixed for me with SC007UK update. There is a thread about this back in 2023.
