Audi A4 - Video tutorial

Model: Audi A4 B6 - Years 2000-2004
Part: Checks and maintenance
Operation: Audi A4 engine yellow warning light meaning

Today we will discover the meaning of the yellow engine warning light that comes on in the dashboard (we are in an Audi A4): this means that there is some anomaly in the engine control unit that does not allow the engine to run smoothly. By connecting the computer to the OBD socket of our car it is possible to carry out a diagnosis that will allow us (not always) to be able to understand the problem of the car, thanks to various sensors placed on the engine. Once the damage has been discovered and repaired, the light is always reset with specific software. In any case, contact a specialized workshop or obtain an OBD control unit to be able to understand any problem.
