If you are an Audi owner, you may have experienced the EPC light appearing on your dashboard while driving. This can be alarming, especially if you notice that your car is shaking or vibrating. In this article, we will discuss what causes the Audi EPC light to come on and the possible solutions to fix the problem.
What is the EPC Light?
The EPC light stands for Electronic Power Control. It is a warning light that appears on the dashboard when there is a problem with the engine or the transmission. The EPC light can indicate a range of issues from minor to severe, and it is important to address the problem as soon as possible.
Causes of Audi EPC Light and Car Shaking
There are several reasons why the EPC light may come on and your Audi may start shaking. Some of the most common causes include:
1. Faulty Throttle Body
The throttle body is responsible for controlling the amount of air that flows into the engine. If the throttle body is faulty or dirty, it can cause the EPC light to come on and your Audi to shake. Cleaning or replacing the throttle body can fix the problem.
2. Malfunctioning Mass Airflow Sensor
The mass airflow sensor is responsible for measuring the amount of air that enters the engine. If the sensor is dirty or malfunctioning, it can cause the EPC light to come on and your Audi to shake. Cleaning or replacing the mass airflow sensor can fix the problem.
3. Faulty Spark Plugs
Spark plugs are responsible for igniting the fuel in the engine. If the spark plugs are faulty or worn out, they can cause the EPC light to come on and your Audi to shake. Replacing the spark plugs can fix the problem.

Fuel injectors are responsible for delivering fuel to the engine. If the fuel injectors are dirty or clogged, they can cause the EPC light to come on and your Audi to shake. Cleaning or replacing the fuel injectors can fix the problem.
5. Low Fuel Pressure
Low fuel pressure can cause the EPC light to come on and your Audi to shake. This can be caused by a faulty fuel pump or a clogged fuel filter. Replacing the fuel pump or fuel filter can fix the problem.
