Hi everyone,
I own a 2023 MG4 Luxury (manufactured in December, 64 kWh battery, ~19,750 km) and I’m currently facing a serious issue:
DC fast charging no longer works — only AC charging via Type 2 (around 10 kW) functions correctly.
I’ve tested the car at multiple DC fast chargers from different providers, but none of them initiate charging.
No error appears on the charger or on the car — it just doesn’t connect.
A yellow warning icon (battery with a slash through it) appears on the dashboard.
Ever since this symbol showed up, DC charging has been completely blocked.
I scanned the car using Car Scanner, and here is the list of DTCs I found:
Any help or advice would be greatly appreciated!
Thanks in advance!
