Volkswagen Sutar engine fault light, where is the 18 Sutar engine fault light

Check the front and rear oxygen sensors first, this thing is broken, the initial appearance is shown in the instrument to show that the engine fault light is always on (or occasionally flashing), but the car can barely drive for a short time;

If it is not repaired for a long time, the computer (ECU) of the electronic fuel injection system will not be able to obtain the information of oxygen concentration in the exhaust pipe, so it will not be able to feedback and control the air-fuel ratio, which will increase the fuel consumption and exhaust pollution of the engine, and the engine will have unstable idling, lack of fire, surge and other fault phenomena. Therefore, it is necessary to troubleshoot or replace it in a timely manner.

Generally, today's cars have two oxygen sensors at the front and rear, respectively in the front and rear of the three-way catalytic converter, and the faulty one should be replaced in time. The failure of this product mostly occurs in the case of mixing gasoline (ethanol gasoline, etc.) with different grades and types of gasoline in different regions, or adding fuel treasure.

If that's the problem, hurry up, don't delay. In 4s, plug in the computer and measure the exhaust gas flow data feedback.

Hello, through your description, if the engine fault light is on, it means that the engine control system signal is abnormal, it can be a line failure, a sensor failure or a control module failure, you need to go to the repair shop in time, use a special computer to detect, analyze the specific cause of the failure, and then make corresponding treatment.

Causes of the engine light on: 1Poor quality of gasoline will cause the mixture to burn inadequately in the cylinder, resulting in polluting lights, and it is also prone to carbon deposits.

2.The presence of carbon deposits in the inlet duct and piston tip will lead to poor atomization, which will lead to insufficient combustion and the pollution lamp will be on. 3.

Cold car starts, especially when the weather temperature drops sharply, due to the computer.

The 18 Sutar engine fault lights are on the dashboard of the car, and the logo is in the shape of a yellow engine. The engine fault light is lit, which means that the engine electronic control system has detected that the engine operating conditions or electronic equipment (various sensors and actuators and wiring) are faulty or not working well, which is divided into current faults and past faults, and does not mean that the engine will be damaged.

Introduction to automobile enginesThe role of the engine in the car is the device that provides power for the car, and the alarm code is the heart of the car, which determines the power, economy, stability and environmental protection of the car. According to the different powers, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors and hybrids.

Common gasoline engines and diesel engines belong to reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy of piston movement and output power to the outside world. The components of the engine are five major systems and two major mechanisms, and the five major systems are the fuel supply system, the cooling system, the lubrication system, the ignition system, and the starting system; The two major mechanisms are the crank connecting rod mechanism and the valve mechanism.

What should I do if the Volkswagen Sutar engine fault light is on? Volkswagen Sutar ( Price |What should I do if the engine fault light is on? If the engine fault light of Volkswagen Sutar is on, you should go to the 4S shop as soon as possible and let the maintenance personnel decode and repair.

The reasons for the engine failure light are as follows: 1. The combustion state is not good: the engine is detonated, the fuel quality is not good, the inside of the engine cylinder is not clean, there is carbon deposit, and the computer cannot obtain the engine data; 2. There are two situations when the engine fault light is on:

Yellow symbol light, indicating that the engine is faulty, but the fault does not affect the normal operation of the engine, but the car needs to be maintained; The red symbol light indicates that the engine has a serious fault and needs to be repaired immediately under normal circumstances. The yellow light indicates that the engine is faulty, but the fault does not affect the normal operation of the engine, but it must be tested and repaired; The red light indicates that the engine has a serious fault, and under normal circumstances, it needs to be repaired immediately, if it is in special road conditions, it can be used in an emergency, but you need to pay attention to the working status of the engine at all times. @2019

Volkswagen Sutar dashboard fault light is generally caused by the fuel emission system, you start and extinguish the vehicle when the fault light is on, start and extinguish the car three times after starting the vehicle you observe whether the fault light is still lit, or it is still lit You need to go to the store in time to check the fault code, to see whether it is an engine problem or a sensor failure, or it may be an occasional failure, you don't need to go to the store in time to check. To eliminate the fault light, you need to go to the 4S store to eliminate the fault code.

Fault indicators, including engine (exhaust system) fault lights, oil system fault lights, battery and power generation system fault lights, etc., these fault indicators are rarely lit, but as long as they are lit, it means that the vehicle has been faulty or abnormal, which affects driving safety and may damage the vehicle if it is large, and needs to be repaired immediately, or contact the brand 4S store of the vehicle for rescue.

The Volkswagen Sutar fault light is basically divided into four categories: the red indicator light means a warning, and the driving should be stopped immediately for maintenance. The yellow indicator light is just an early warning, just deal with it as soon as possible.

The blue indicator lights warn car owners to be careful about whether the high beams will affect other vehicles. Green indicators are functional lights, such as low beams, width indicators and turn signals.

Volkswagen Sutar fault lamp:

1. Cleaning liquid level. The indicator light is on, which means that it is time to fill the glass water.

2. Brake friction pads. It means that the friction plate is badly worn and loses its effectiveness. It should be noted that the friction plate on one shaft should be replaced at the same time.

3. Steering locking system. There is a fault in the steering system, and steering will be extremely difficult. Do not tow the vehicle at this time, it will cause danger.

4. Tire inflation pressure monitoring system. This fault light will be lit when the pressure of the tire is high or low, and of course it may be that the information is not re-entered after the tire change.

5. Electromechanical parking brake. It is used to monitor whether the electric handbrake is working in place, release the parking brake, and the indicator light must be turned off. The indicator light flashes continuously, indicating that the braking force is not enough to prevent the vehicle from moving. (Photo by Tang Longlong, Pacific Automobile Network).
