Passat cannot continue to be driven when the EPC light is on. EPC: EPC is the abbreviation for the Electronic Throttle Control system, which assists in engine power control. It involves many components, including the engine control unit, electronic throttle body, accelerator pedal position sensor, brake switch, clutch switch, power steering switch, alternator load, wiring, etc. If any of these components malfunction and cause inaccurate power control by the engine control unit, the EPC warning light will activate. It is recommended to take the vehicle to a specialized repair shop for a comprehensive inspection of these components. Reasons for the indicator light and solutions: There may be a fault in the electronic throttle control system; the brake switch may be damaged. Clean carbon deposits in the throttle body area; after cleaning, use specialized diagnostic equipment to relearn and match the throttle position. The normal opening degree should not exceed 2.0%.
