If the engine warning light remains illuminated on the instrument panel, you need to check the fault memory of the engine management unit to understand the source of the anomaly. This operation is performed by connecting a diagnostic tool to the OBD (On Board Diagnostics) socket that can communicate, through appropriate protocols, with the engine control unit.

The OBD socket is located beneath the panel directly under the steering wheel: rotate the central screw, remove the panel, access the OBD socket and connect the diagnostic tool interface; then start the program by selecting the make, model, year, and engine type of the vehicle; then read the error codes and try to clear the fault memory; if the fault reoccurs, further investigation will be necessary.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
