The causes behind the engine light staying on

For many reasons, the engine light stays on in your Audi A4. The following points define the causes behind the activated engine light in your car.

Failed catalytic converter

In your car, the catalytic converter is used for controlling the exhaust emissions produced by the internal combustion engine and filters out the harmful byproducts in the exhaust gases and burns them up.

When the catalytic converter is failed, you will notice that harmful exhaust emissions are produced from the exhaust system that can pollute the environment, reduce the efficiency of the engine and activate the engine light on the dashboard.

Wiring issues

Apart from the other causes, the wiring harness and the problems within the spark plugs also activate the engine light in your Audi while driving on the road. Left untreated for longer can cause severe damage to your car such as failing the catalytic converters, wearing out the ignition coils and damaging the oxygen sensor.

When it happens, you have to bring it to a licensed mechanic to look at the wiring problem and fix it efficiently for smooth driving.

Bad oxygen sensors

Thus, the main purpose of the oxygen sensor in your car is to control the exhaust emissions of gas engines. It is commonly measuring the amount of unburned oxygen available in the exhaust. If the oxygen sensor of the car is failed, then it can reduce the gas mileage, trigger the engine light, and affect the functions of the catalytic converter.

Ignoring the problem for longer can cause significant damage to the catalytic converter and affect its functions. So, when it happens, you have to consult a mechanic for diagnosing the problem and fix it as soon as you can.

Failed mass airflow sensor

The main function of the mass airflow sensor in your car is to measure the airflow into the engine and maintain the air-to-fuel ratio in the internal combustion engine for a smooth combustion process.

If the mass airflow sensor of the car is failed, then it could affect the fuel efficiency, activate the engine light, and reduce the engine performance. So, inspect the failed mass air flow sensor by a mechanic for fixing the problem.
