How to solve the trouble of Volkswagen epc

EPC light is mainly caused by dirty throttle body. This situation can be solved by cleaning the throttle and then re-matching. There is also a leak in the air intake system, which causes the engine control unit to light the EPC warning light after detecting this problem.

If the above problems occur, you can stop the car, turn off the ignition switch and restart the engine. If the fault light goes out, it is an accidental fault. You can continue driving and drive the vehicle to the maintenance agency for maintenance as soon as possible. If the fault indicator does not go out after restarting the engine, it proves that the fault still exists. You can drive in the same place or at a low speed. If the refueling door does not respond, it is recommended not to drive as much as possible.

Matters needing attention in automobile throttle

When cleaning the throttle valve, the throttle valve must be removed for cleaning, so that the cleaning can be carried out, and the electric part of the throttle valve will not be sprayed because the cleaning liquid is sprayed in only one direction, which will seriously damage the throttle valve.

When cleaning the throttle, spray the throttle cleaning solution to the position with more carbon deposits, wait for 5- 10 minutes, and the carbon deposits will be dissolved by the cleaning solution. At this time, brush with a clean brush and wipe with a clean towel. Before installation, you must wait until the throttle cleaning solution is completely dry before installation, otherwise the position sensor will be damaged.
