Mg4 Firmware Update ((new)) 🎉

This report details the current state of firmware updates for the MG4, covering update methods, known issues, and the 2026 model refresh. Current Update Methods

Contrary to many modern electric vehicles, the MG4 primarily relies on dealer-based servicing for critical system updates. Dealer-Led Updates

: Most core system updates (battery management, safety systems, powertrain) must be performed at an authorized MG service center.

: The vehicle is connected to a diagnostic computer to download and install proprietary files.

: Timeframes vary significantly. While minor fixes take 20 minutes, major cumulative updates (e.g., 18+ individual modules) can require the vehicle to stay at the dealership for 1 to 3 days. Over-the-Air (OTA) : While higher trims like the MG4 Essence

have hardware capable of OTA, the feature is not widely active for major firmware updates as of early 2026. Some owners receive infotainment-specific notifications, but these are often limited to minor software tweaks or app-based updates. USB Updates

: Used primarily for navigation map refreshes or by technicians when standard diagnostic software fails to push an update. Key Firmware Versions & Fixes mg4 firmware update

Firmware releases focus on resolving "micro-aggressions" in the user interface and critical safety bugs. www.which.co.uk MG4 software updates and firmware versions?

Updating your firmware is less like a modern smartphone update and more like a traditional dealership pitstop. While the car has the hardware for over-the-air (OTA) updates, MG has historically required owners to visit a service center to have new software "flashed" manually by a technician. 🛠️ The Dealership Dependency

Unlike a Tesla, you typically won't see a "Download Now" prompt on your dashboard. Most MG4 owners receive updates during scheduled maintenance or if they specifically report a fault to their dealer.

The "Workaround": Many owners have found that dealers won't update the car "just because." To get the latest firmware, you may need to mention specific issues like Bluetooth dropouts or overly sensitive driver aids.

Update Duration: Depending on the size (like the R59 update), it can take anywhere from a few minutes to several hours as it involves updating multiple vehicle modules. 🚀 Key Recent Updates (R59 / R11)

The most significant firmware jump for the MG4 (particularly the Trophy and Essence trims) has been the R59 (or R11) update. It addressed several of the car's most vocal criticisms: This report details the current state of firmware

Taming the ADAS: The Lane Keep Assist (LKA) is significantly less aggressive. A new shortcut in the swipe-down menu also makes it easier to toggle off.

Cruise Control Logic: Adaptive Cruise Control (ACC) now adjusts speed in 5 mph/kph increments with a long press and remembers your last distance setting.

Safety Fixes: Specifically addresses "phantom braking" issues related to the Advanced Driver Assistance System (ADAS).

Infotainment: Includes better Bluetooth stability and fixes for radio station icons (e.g., BBC stations in the UK). ⚠️ Common Firmware "Niggles"

Despite updates, owners still report a few persistent software quirks:

The "Kamikaze" Lane Assist: Even with the update, some find the LKA can still be unpredictable on roads with unclear markings. How to check if your MG4 has the update

Disappearing Features: Some owners reported that the "Battery Health Mode" (limiting charge to 80%) went missing after certain updates.

USB Playback: The infotainment still tends to sort USB music alphabetically by track name rather than by album or folder structure. 🔮 Looking Ahead: 2026 Refresh

MG has begun rolling out a 2026 update (already appearing in some markets as the MG4 "Urban" or refreshed base model). This includes hardware-linked software improvements like a larger 12.3-inch screen, HD 360-degree cameras, and better energy cycle management.

If you'd like to check your current version, you can usually find it under Settings > System > Software Information on your infotainment screen.
