If your Audi is displaying an EPC light on the dash, it means that there is a problem with the electronic throttle control system. The first thing you should do is check the throttle body for any debris or build-up that might be causing the issue. If there doesn’t seem to be anything blocking the throttle body, then the next step is to check the throttle position sensor. This sensor tells the computer how far open or closed the throttle body is, and if it’s not working properly, the EPC light will come on.

These wires can sometimes get damaged or corroded, so it’s important to check them for any signs of wear or tear. If you find any damaged wires, you’ll need to replace them before the EPC light will go off.
