Today, you will discover the meaning of the yellow engine light that turns on in the dashboard (we are in an Audi A4): this indicates that there is some anomaly with the engine control unit that prevents the engine from functioning properly. By connecting a computer to the OBD port of your car, you can perform a diagnosis that may (not always) help you understand the car's problem, thanks to various sensors located on the engine.

Once the damage is identified and repaired, reset the light using specific software. In any case, consult a specialized workshop or obtain an OBD scanner to understand any potential issues.
