The Mercedes-Benz engine fault light is on, but there is no problem. What's the matter?

1. Fuel quality problem: fuel quality is not up to standard. Some car owners have just finished refueling, and the engine fault light lights on the dashboard, which is generally caused by adding poor quality oil at non-standard gas stations. This situation will not affect the driving of the vehicle, but it will cause damage to the engine.

2. The specific reasons are as follows: Error: The information transmitted by the sensor is wrong, or the sensor instantly detects that the operating status of the vehicle exceeds the initial calibration limit. At this time, the engine fault light will be notified to remind the owner that there is a problem with the vehicle. The most common point is the lack of vehicle power, resulting in confusion of the internal signal of the sensor system, resulting in engine failure.

3. The reasons are as follows: the problem of fuel quality. The quality of fuel is not up to standard. Some car owners have just addedAfter running out of oil, the engine fault light lights up on the dashboard, which is generally caused by adding poor quality oil at non-standard gas stations. This situation will not affect the driving of the vehicle, but it will cause damage to the engine.

4. Pulled and dragged by other vehicles. Borrow the power supply of other vehicles to start. Use the downhill to start.

5. The reasons why the engine fault light of Mercedes-Benz is as follows: fuel quality problem: fuel quality is not up to standard. Some car owners have just finished refueling, and the engine fault light lights on the dashboard, which is generally caused by adding poor quality oil at non-standard gas stations.

6. Reasons and methods for the engine fault light: fake fault. The fault code is reported, but it works normally. It may be that an operation is beyond the control of the computer. The fault code feedback by the computer can be eliminated first, and then see if the fault code is still skipped.Small malfunction.

What is the reason why the Mercedes-Benz engine fault light is on

1. There are the following 7 main reasons why the Mercedes-Benz engine fault light is on: Sensor: The sensors mentioned here include water temperature, crankshaft position, and empty air flow , intake temperature, oxygen sensor, etc.

2. The quality of fuel does not meet the standard. Some car owners have just finished refueling, and the engine fault light lights on the dashboard, which is generally caused by adding poor quality oil at non-standard gas stations. This situation will not affect the driving of the vehicle, but it will cause damage to the engine.

3. The Mercedes-Benz engine fault light is on, and there are three situations: false fault, minor fault and major fault. The specific reasons are as follows: Error: TransmissionThe information transmitted by the sensor is wrong, or the sensor instantly detects that the operating state of the vehicle exceeds the initial calibration limit. At this time, the engine fault light will be notified to remind the owner that there is a problem with the vehicle.

4. Poor engine maintenance is the most common cause of engine failure. Therefore, it is recommended that the car should be maintained on schedule and maintain good driving habits, otherwise the engine operation burden will be aggravated.

5. The reason why the Mercedes-Benz engine fault light is on: There are many cases where the engine fault light alarm is caused by abnormal engine oxygen sensor.

6. After the inspection of the Mercedes-Benz, the dashboard shows that the engine fault is abnormal. The Mercedes-Benz engine fault light is on. There are three situations: false fault, minor fault and major fault. The specific reasons are as follows: Error: The information transmitted by the sensor is wrong, or the sensor instantly detects that the operating status of the vehicle exceeds the initial calibration limit.

What should I do when the Mercedes-Benz engine fault light is on

It is necessary to turn off the engine immediately, and then check the motor vehicle. The inspection parts include: the relevant sensors of the vehicle, the position is the water temperature, the crankshaft , air flow, near-air temperature, oxygen sensor, etc. The vehicle was not maintained on time. There is something wrong with the oil used.

Detect that the coolant temperature is abnormally below the normal value range, the reason is that the coolant thermoster is stuck, and it is judged that the thermoster is damaged. After replacing the thermost, use the diagnostic computer to test, and the test is normal. There is no abnormality in the test drive, troubleshooting.

You need to turn off the engine immediately and then check the motor vehicles, including: 1. The relevant sensors of the vehicle are located in water temperature, crankshaft, air flow, near temperature, oxygen sensor, etc.The vehicle was not maintained on time. There is something wrong with the oil used. Which country's brand is Mercedes-Benz? It is a German car brand and a luxury car brand.

There is a false failure in the engine: you can try to start and turn off the vehicle three times in a row, or turn off the engine and unplug the negative pole of the engine battery, wait for 30 seconds to connect it, and then try to start. After completing the above method, check whether the engine fault light on the dashboard is still on.
