By following this guide, you'll be able to keep your MG4's software up-to-date, ensuring a safe and enjoyable driving experience.

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 mg4 software update

The story of updating an MG4’s software is often described by owners as a journey of patience, dealer visits, and notable quality-of-life improvements. Unlike many modern EVs, the MG4 typically requires a trip to a service center for major module updates rather than receiving them over-the-air (OTA) The Service Center Experience

The update process usually starts with a scheduled service visit. Owners often report that the car needs to be left at the dealership for a full day. This is because the car contains multiple distinct modules (like the ADAS system, climate control, or motor tray) that each require separate updates. At some locations, such as the MG Indooroopilly Dealership

, dealers may now require owners to specifically mention a problem (like AEB or Lane Keep Assist issues) before they will initiate a module update. Key Improvements After Updating

When the software is successfully brought up to date, drivers often notice several significant changes: Refined Adaptive Cruise Control

: Older software often slows the car aggressively on bends or only allows speed adjustments in 5 km/h increments. Newer versions generally allow for more precise 1 km/h adjustments Enhanced Interface

: A "swipe down" shortcut menu for climate and car settings is a common addition found in updated infotainment systems. Smoother Safety Features

: Updates frequently focus on smoothing out the Lane Keeping Assist (LKA) and Emergency Lane Keeping (ELK) systems to make them less intrusive during daily driving. Improved Cabin Comfort

: Some updates address the "calibration" of the climate control, ensuring that the temperature on the screen more accurately reflects the actual air temperature in the cabin. How to "Prepare" for the Update Document Issues

: Since some dealers only update modules if a fault is reported, keep a list of specific quirks (e.g., "Lane Keep is too aggressive" or "AEB warned unnecessarily") to share with the service advisor. Allow Time

: Expect the car to be "plugged in" for several hours or the entire day. Manual Map Updates

: While system software is a dealer task, you can often update the navigation maps yourself using a USB stick and the Naviextras Toolbox currently available in your region? Pilot software update in March for MG? - Facebook 18 Feb 2026 —

Keeping your car's software current is essential for optimizing performance, safety, and the overall driving experience. For MG4 owners, a software update can resolve common glitches, improve efficiency, and even unlock new functionalities. Current Software Versions and Key Updates

MG frequently releases updates to address user feedback and technical bugs. Several significant versions have been identified by owners and technical forums:

R59 (for Trophy/Luxury models): This major update, often part of the SCUK00001 service campaign, focuses on both the infotainment system and underlying car modules. Notable changes include:

Safety Features: A new shortcut in the drop-down menu for easier deactivation of Lane Keep Assist (LKA). MG4 software is split into two distinct categories,

Cruise Control Improvements: Adaptive Cruise Control (ACC) now responds more predictably to button presses (adjusting speed by 5 mph with a long press) and remembers the last distance setting.

Driving Dynamics: Fixes for the "slowing down in curves" issue and smoother Traffic Jam Assist (TJA) operation.

R33 (for SE/Standard models): This version brought back the external temperature display on the infotainment screen and added the LKA deactivation shortcut.

R63: Primarily addresses HVAC temperature scaling issues, ensuring the target temperature more accurately matches the actual cabin temperature. How to Update Your MG4 Software

Unlike some modern EVs, the MG4 currently relies heavily on dealer-based updates rather than consistent Over-the-Air (OTA) functionality. MG4 Software updates | MG4 EV (2022 to 2025) Forum

Technicians connect the vehicle to a computer to download and install files across various control units (e.g., CCU, BCM, EVCC) Updates are time-intensive, often ranging from several hours

to an entire day, depending on the number of control units being updated OTA Status: While there is high owner demand for reliable OTA updates

Not everyone loves the new update. MG has slightly nerfed the acceleration in Eco mode to preserve range. If you drive mostly in Normal or Sport, you won't notice. But if you lived in Eco, the car feels a tiny bit lazier off the line post-update.

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
