Audi epc lights up and the car shakes. Can you keep driving?

The light of Epc indicates that there may be a fault in the electronic throttle system, which will affect the normal use of the vehicle. Can't continue driving, you need to drive to a professional vehicle maintenance center to find someone to check and repair.

EPC is the full name of engine electronic power control system, also called electronic throttle. You can try to turn off the fire and restart it to see if the epc light is still on. If it doesn't light up, it means there is no problem, but the epc light is affected by false alarm; If the epc light is still on or always on, the following solutions need to be taken:

1, air intake system failure, such as leakage or blockage.

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.

This situation can also be extended to the situation when the engine is started. Do not pull out the fuel gauge or open the fuel filler cap. Otherwise, the engine controller will misjudge that there is air leakage in the engine route, and at the same time, it will also cause a fault, which will lead to the EPC light being on and the engine shaking. If there is a leak in the crankcase ventilation system, this fault may also be caused.

Solution: Clean the throttle body.

2. The throttle body is dirty and has too much carbon deposit;

Remove carbon deposits in related parts.

3.ECU failure.

Rewrite ECU related data.

Extended data:

The electronic throttle control system can accurately control the throttle opening, which can not only improve fuel economy and reduce emissions, but also make the system respond quickly and obtain satisfactory handling performance. On the other hand, it can realize the integration of idle speed control, cruise control and vehicle stability control and simplify the structure of the control system.

There is no special restriction on the throttle. Generally, it will be cleared when the idle speed is unstable. It has something to do with the air environment of the car, the type of oil used, the interval between changing air filters and the habit of opening the electronic throttle.

Generally, people will clean the vehicle when the working condition of the vehicle begins to deteriorate (unstable idle speed and obvious engine jitter during cold start). In fact, it is recommended to find a familiar repair shop and connect the computer to check the throttle opening every once in a while (generally free of charge). If the opening is less than 5%, it can be cleaned.
