What is the common EPC fault in the 2007 A6L?

[MackenzieFitz]

2007 A6L common EPC fault is an electronic throttle failure. Causes of electronic throttle failure: Damaged throttle position sensor. Poor contact, open circuit, or short circuit in the throttle position sensor wiring. Incorrect initialization position. Excessive carbon buildup in the throttle. Damaged throttle servo motor. Poor contact or short circuit in the throttle servo motor wiring. Fault in the engine control unit. Electronic throttle fault diagnosis: Use a computer diagnostic tool to read freeze frame data. When a DTC (Diagnostic Trouble Code) is stored, the ECM (Engine Control Module) records vehicle and driving condition information as freeze frame data. During troubleshooting, freeze frame data helps determine whether the vehicle was running or stopped when the fault occurred, whether the engine was warm or cold, whether the air-fuel ratio was lean or rich, and other data.
