This is the only part of the car that typically updates via OTA (Wi-Fi). This changes the UI, wallpaper, and basic clock settings.
The MG4’s Wi-Fi module is weak.
Troubleshooting: If the car says "No update available" but you know a newer version exists, your VIN has not been whitelisted by MG for OTA. You must visit a dealer.
The MG4 is a brilliant car trapped behind mediocre software. A successful MG4 software update transforms it from a glitchy prototype into the smooth, efficient hatchback you paid for.

The MG4 software update process is primarily dealer-led, as MG currently does not widely support Over-the-Air (OTA) updates for major system improvements. Updates are typically performed during scheduled maintenance or if a specific issue is reported. Key Update Improvements
Recent software versions have addressed major driver concerns and added features:
Safety Enhancements: Updates have significantly improved Autonomous Emergency Braking (AEB) and Lane Keep Assist (LKA), reducing "jerky" interventions.
Driving Features: The One Pedal Driving (OPD) function was added to 51kWh variants.
Infotainment & Comfort: Improvements include a persistent touchscreen status bar, refined HVAC controls, and more accurate battery consumption statistics.
Connectivity: Updates have refined iSmart connectivity and addressed bugs in Apple CarPlay, such as screen orientation issues. How to Get an Update
Because MG often limits updates to cars with documented issues, following these steps can help ensure your vehicle is current:
Report Specific Issues: Some dealers only apply updates if you complain about a specific problem, such as "phantom braking" or "erratic lane keeping".
Request During Service: Ask your local MG Dealer to check for and install all available updates during your next scheduled service.
Check Your Version: You can view your current software version (e.g., R33, R46, R63) through the vehicle's "Engineer Menu" or system settings to compare with the latest community-tracked versions on the MG EVs Forum. Common Version Landmarks Key Changes R33 / R46
Improved HVAC controls, battery status fixes, and energy stats. R59 / R63
Introduced a drop-down menu to disable LKA and further infotainment stability. R11 (AU)
Specific to Australia; refined iSmart, improved adaptive cruise control (ACC), and persistent status bar. MG4 Phantom Braking Software Update and Installation
For the MG4 EV, software updates are generally managed through authorized MG dealerships rather than standard over-the-air (OTA) methods common in other EVs. While the car has a SIM card, it is primarily used for the MG iSMART app's remote functions rather than major system-wide updates. Key Methods for Updating
Dealer Installation: This is the official and most reliable method. Most owners receive updates during scheduled maintenance or by booking a specific software service appointment.
Manual Request: Because some dealers do not automatically check for updates, you may need to explicitly ask for them. Mentioning specific issues, such as "phantom braking" or wanting to enable "One Pedal Driving" (OPD), can help ensure the dealer performs the update under warranty.
DIY Engineer Menu: Advanced users sometimes access the "Engineer Menu" to update components like the AVN-SOC (MPU) or Infotainment System ECU (MCU). This typically requires specific files on a USB drive and carries a risk of "bricking" the system if done incorrectly. Latest Known Improvements (2024–2026)
Updates are released to address system stability, safety features, and new functionalities:
Safety (AEB): Bulletin # AS-TEC-07022024-01 was released to address "phantom braking" issues in the Automatic Emergency Braking system.
One Pedal Driving (OPD): A major update for early models (specifically the Excite 51) to enable single-pedal driving capability.
System Versions: Recent system versions reported by users include R21, R63, and MCU 69.3. How to Check Your Current Version To see if your car is running the latest software:
Are software updates for MG4 free or paid after warranty? - Facebook
Even after an update, glitches happen. Here are the top three complaints solved:
1. The "Black Screen of Death"
2. "Lane Keep Assist Resets to ON every drive"
3. eCall (SOS) System Fault Error
MG markets the MG4 with "OTA capability." However, there is a massive distinction between the two types of updates.
Update Process
Once you've initiated the update, the process will begin. This may take several minutes or up to an hour, depending on the size of the update and your internet connection.
