What does Audi epc mean?

Generally speaking, there are two possibilities for EPC lights to turn on. First of all, the throttle is dirty and needs cleaning. In another case, the brake light is not on, so it is necessary to check the brake switch and wiring. Because of the oil problem, the EPC fault light will also light up.

When the EPC light is on, check the electronic throttle body first. You will find that the throttle is too dirty. Clean the throttle and then make basic settings.

Namely EPC electronic power control and engine electronic power control system. In EPC system, the engine control unit (ECU) calculates the optimal target throttle opening according to the position data fed back by the pedal sensor, and sends a signal to the throttle drive motor to make the throttle rotate to this angle. The power of the engine can be controlled by controlling the opening of the electronic throttle of the engine.

Processing method when the extended data general contracting light is on;

1. Troubleshoot the air intake system, select qualified fuel and clean the throttle body.

2. Remove carbon deposits on related parts and clean them.

3. Rewrite the relevant data of ECU (the situation that cannot be ruled out after solving other faults).

4. Do not rule out the possibility caused by other faults, and then carry out maintenance according to the test results of real vehicles.
