How to Turn Off the Engine Warning Light on a Dr 3?

Model: DR 3 MK 1 - Years 2018-2026
Part: Warning light – error code

The engine warning light, which is yellow and illuminated, indicates a variety of faults in the vehicle, such as an inefficient fuel pump, dirty injectors, oxidised spark plugs, a dirty lambda sensor, and so on. When this warning lights up, it is clear that you need to address and investigate the cause and resolve it, but if the light does not turn off by itself, it must be done forcibly. For this, you can refer to the tutorial provided: connect your smartphone via cable, equipped with the appropriate app, to the OBD2 port of the vehicle, located under the dashboard on the left side, connect via Bluetooth, configure the vehicle model, and once the active fault is found, delete it.
