The MG MG3 is a keenly priced supermini that punches above its budget billing with a generous standard kit list, including electronic service monitoring. Once an oil change or wheel swap is done, that system needs resetting so the dashboard stops flagging overdue maintenance. On the MG3 you will usually carry out an oil service reset, clear the service-interval reminder, and run a TPMS reset after correcting tyre pressures. MG revised the cabin and its menus across the model’s life, so the procedures differ between earlier and later cars. Select your MG3’s generation below to follow the appropriate guide.
