I think you’re on to something; ours was serviced recently (2nd year) and pre-heat/demist works fine, but I know for certain that they didn’t do any SW updates??
Don’t think I will be ever be able to clarify this for everyone, but I will try anyway:
an equalisation charge and cell balancing are the same thing
the important step for balancing is to reach 100% while AC charging, starting SoC is irrelevant
the BMS will decide if balancing is required...
The short answer is no, after 100% SoC is reached (AC charging only) the BMS checks if there is a voltage difference between the individual cells and (only if there is) starts the balancing process.
Starting @ low SoC is done for a different reason altogether (calibrating the BMS).
The video...
Before you go about a warranty claim you will find out if the car is still covered.
It’s not a requirement to have it serviced by a MG dealer if the works are done in time and according to MG’s maintenance procedures.
Given MG’s notorious inflexible around all things warranty related, the most...
It should not enter sleep mode when used daily.
Try a HW reset (disconnect 12V battery minus pole for a couple of minutes, then reconnect it) start the car, move steering wheel fully in both directions to clear faults.
Not sure what exactly you’re looking for, but the CCU charges the aux battery every time the car is READY or charging.
Probably the easiest way to achieve your goal is put the second battery in parallel with your aux and disconnect it once the voltage drops below a certain level.
More than likely the update will still be required, unless a dealer showed some initiative? But luckily it’s now possible to do this DIY style:

DC charging is using the AC signal connections of the charge port but completely bypasses the AC/DC section of the CCU.
I wouldn't rule out corrosion on the AC contacts completely, but the likelihood of an issue further downstream (CCU, EV-ECU) is far more likely.
As always with intermittent...
This seems to be a general ‘bug’ as ours does the same on ‘high’? I wouldn’t bother bringing it to the dealer, just use the windscreen demist setting instead…
