What is the lighting treatment method of Tiguan epc lamp?

Under normal circumstances, dirty throttle body, vacuum leakage of intake system, broken brake switch and failure to upgrade engine in time may all lead to EPC failure. Because the throttle body is too dirty, this situation can only be solved by cleaning the throttle and re-matching. Due to the failure of the brake light switch, on-site inspection and post-treatment are needed.

There is a leak in the air intake system, which causes the engine control unit to light the EPC warning light after detecting the problem. If there is a leak in the crankcase ventilation system, this fault may also be caused. Serious or obvious vacuum leakage is not a problem, only slight leakage can not be effectively detected by the control unit. If the compensation adjustment made by the control unit exceeds the limit allowed by the internal program of the control unit, the control unit will judge that there is something wrong with the electronic throttle system, and the EPC fault light will light up.

The EPC fault light is always on, indicating that the engine management system or electronic control is out of order, which is often accompanied by unstable idle speed of the vehicle or engine jitter during cold start. Generally, due to the domestic oil quality and dirty vehicle environment, it is necessary to drive to the maintenance service station as soon as possible for maintenance.
