An EPC light is an electronic power control system warning light. It is usually located in the instrument cluster of your Audi and indicates that there is an issue with the engine computer or powertrain.
The average cost of an EPC light will cost $350. Repairs can cost anywhere from $100-$800 depending on whether you visit a mechanic, dealership, or Audi service center. The price will also vary depending on whether the light just needs a reset or extensive damage needs to be repaired.
The type of Audi you have will also help determine the repair cost of an EPC light. The repair cost for a 2002 Audi A4 sedan equipped with a 2.0L, four-cylinder engine will only be about $100-$350 at most mechanics and service centers if there is no extensive damage.
However, if you have an Audi A6 3.2L V-6 engine in your car, the repair cost for an EPC light can be as much as $800.

What Does The EPC Light On My Dash Mean?
EPC stands for electronic power control. When your Audi’s engine is running correctly, it will have the EPC light on during startup but then turn off shortly after.
If the light appears while you are driving, it means that there is a problem with your car’s computer system or with your vehicle’s powertrain. The light appearing can happen for many reasons, including an oil change.
It’s vital to get the light checked out as soon as possible to try and prevent more damage from occurring.
The EPC light is not the same as the check engine light on some other cars; it’s a different warning altogether. While some manufacturers will use one single warning light for both systems, Audi has separated them.
