The MG MG3 Mk1 (SZP1) 2011-2023 was MG’s affordable supermini, offered with a willing 1.5-litre petrol engine and personalisation options that kept it popular as a value buy. After servicing, its instrument cluster holds counters that need clearing so the dashboard stays accurate. An oil service reset removes the service interval prompt, and a service reminder reset clears the maintenance light. Depending on the job you might also need a TPMS reset after a tyre change and a brake pad wear reset once new pads are fitted. A replacement 12V battery may require registration. Pick the reset procedure for your MG3 from the list below to follow the correct steps for your car.
