I've personally experienced the EPC light coming on in my Volkswagen Tiguan. While driving, a sudden yellow warning light flashed on, which really spooked me. The EPC light indicates an issue with the electronic throttle control, which could be caused by a dirty throttle body with excessive carbon buildup, a faulty throttle pedal sensor, or some malfunction in the engine control unit. When my light came on, the throttle response became sluggish and acceleration felt weak, so I immediately drove to the dealership for inspection. It turned out the throttle body had never been cleaned - cost me just over 200 yuan to fix. Don't ignore it, as prolonged neglect may lead to increased fuel consumption or even breakdown risks. My advice is to have technicians clean the throttle body during regular maintenance, which can prevent similar issues and give you peace of mind while driving.
