More information about the Audi EPC system
Audi Electronic Power Control is a computerized system designed to optimize the efficiency and performance of the A4’s engine. Specifically, the EPC system allows you to manage and optimize the vehicle’s stability control and cruise control.
When working properly, you will never realize that the car’s EPC system is activated. However, when this computerized system experiences problems, you will know because your vehicle will likely lose acceleration power and a warning light will turn on.
What does the EPC warning light mean on an Audi A4?
If you notice your car’s EPC light on the dashboard, don’t worry if other warning lights are also on. Since the EPC system works in conjunction with other vehicle systems, a problem with the EPC can cause other warning lights to come on.
If you notice that your car’s throttle power is having trouble after the EPC light comes on, you’ll want to get off the road as quickly and safely as possible. From there, have your vehicle towed to a service center for further diagnosis and repair.
If your car is still running fine, it is always recommended that you limit driving to your local mechanic or an authorized Audi service center so as not to further damage the vehicle.
In most cases (as explained in this YouTube video), an EPC light is caused by something as simple as a dead battery or a faulty sensor. However, the only way to know the exact cause is to have an OBD2 scanner read the problem code.
You can request that this code be read at any dealership or mechanic. From there, you can make any necessary repairs and get back on the road as soon as possible. However, it is important not to ignore this problem, as it can damage the engine over time.
