Common MG4 Firmware Update Problems (And How to Fix Them)

Despite best efforts, updates can fail. Here is the troubleshooting hierarchy for a failed MG4 firmware update.

🔁 How to Update

There are two main ways:

1. Over‑the‑Air (OTA) – For infotainment and some minor modules.
   Go to Settings > System > System Update on the main screen. Connect to Wi‑Fi (or use the car’s built‑in 4G) and follow the prompts.

2. Dealer update (USB / diagnostic tool) – Most vehicle control modules (BMS, VCU, EPS, etc.) require a dealer visit. These aren’t OTA‑capable on the MG4. If you’re experiencing specific issues (e.g., heated steering wheel not working, erratic ACC), ask your service centre to check for outstanding campaigns.

🗣️ Owner Tip

“After the November 2024 dealer update, my Trophy’s adaptive regen feels much more natural. And the infotainment boot time dropped from 45s to ~20s.” – MG4 owner on an EV forum.

The "Dealer Only" Essentials: BMS and VCU Updates

Do not rely on OTA for safety. The most critical MG4 firmware update for the longevity of your car is the Battery Management System (BMS) . What is the MG4 firmware update

How to know if you need a dealer BMS update:

• Your DC fast charging speed drops to 40kW on a 150kW charger.
• The state of charge (SOC) jumps erratically (e.g., from 50% to 55% instantly).
• The estimated range plummets faster than the actual energy consumption suggests.
• You receive the dreaded "Reduced Propulsion" warning on the highway.

Action Plan: Call your MG service center. Ask them explicitly: "Is there an open recall or technical service bulletin (TSB) for the VCU or BMS for my VIN?" Many dealers will not proactively inform you; you must ask for the MG4 firmware update during a service appointment.
