What should I do if the Volkswagen Bora light is faulty and the Bora engine fault light is on

The reason why the Bora engine failure light is on:

1. If the combustion state of the engine is not good, the fault light will be on. In order to ensure that the engine of the car is in good working condition and maintain the normal service life, an oxygen sensor is installed to detect the combustion state of the engine during the design. If the combustion condition of the engine is not good, it will increase fuel consumption and wear, and it will also pollute the environment.

2. Poor fuel quality. Automobile engines have certain requirements for the quality of fuel, and now the requirements for fuel quality are getting higher and higher. If the quality of the oil you add is not good, of course the engine failure light will come on.

3. There is carbon deposit in the engine cylinder. As the operating time increases, a certain amount of carbon deposits will form inside the engine. These deposits can cause changes in the engine's design parameters.

4. When the thermostat is abnormal, the engine fault light will also be on. If you see that the water temperature gauge does not rise to the ideal temperature (usually 90 degrees) for a long time in the car, the engine fault light will turn on.

Engine misfire.

If the spark plug ages, it can cause the engine to catch fire, and the engine fault light will come on. Remove the spark plug and observe if the electrode void is too large and if there is any black particulate material around it. If this is the case, it can be confirmed that the spark plug is aging and that the engine is catching fire.

Solution 3: Replace the spark plug, the cost of 4S shop is about 150-200 yuan, and the cost of repair shop is about 100-250 yuan. Spark plugs are wearing parts and are not covered by warranty, and it is recommended to replace them after 20,000 kilometers.

There are usually the following reasons for the engine failure light to be on: 1. Poor combustion state The poor combustion state of the engine is the main reason for the engine failure light. 2. There are usually three situations of engine knocking:

The first case: the car is weak; The second case: the car is weak and the engine noise is too loud; The third case:

There is a noticeable knocking sound.

Vehicle 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 and 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 sensor failure, or it may be an occasional failure can not be checked in time to the store.

Hello, the engine indicator light is yellow.

It is an engine clearance fault, which indicates that the engine control system has detected the engine condition or the signal of a sensor is out of alignment.

The reason for the yellow light of the engine indicator light is: the combustion state of the engine is not good; engine knocking; The fuel quality is not good, and the inside of the engine cylinder is not clean and there is carbon deposit.

The way to solve the yellow light of the engine indicator is: go to the auto repair shop to use the car computer testing instrument, detect the engine system, read the fault code, you can find the car problem, and then repair it according to the fault content, not blind action.

Reasons for the engine failure light: 1. The sensor is damaged, the contact is poor or the signal is interrupted; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioner filter is blocked.

1. Sensor problems; The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to turn on. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, and these will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally turn on the fault light to warn of the intake air intake problem; When the engine burns, it needs to take intake, the air filter element is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly, and it will be blocked for a long time, and if it is serious, it will cause the engine failure light to turn on. pressurization issues; Intake booster lines and turbochargers can also cause engine failure lights to illuminate.

The most common of these is turbocharger damage, while the vehicle can also experience symptoms such as oil leakage, high oil consumption, loss of power, metal noise, and blue or black smoke from the exhaust pipe. 7. Exhaust problems; Rear oxygen sensor, three-way catalytic converter, exhaust camshaft and bearing. The most common of these is a failure of the three-way catalytic converter that causes the engine failure light to illuminate.

The use of leaded gasoline, the use of leaded or silicone lubricant additives, the bump of the three-way catalytic converter, and the failure of the engine oil supply system are some of the factors that can easily cause the failure of the three-way catalytic converter. anti-theft system; If the car's electronic immobilizer fails, or if the immobilizer does not match the engine electronic controller, the immobilizer system will also cause the engine to not work properly and the engine fault light will be lit at the same time.

On the car, this fault light yellow can be driven. But it is also necessary to find it as soon as possible, there is no factory for maintenance in general, well, there will be faults. But it can be exercised. In many cases, it is fuel-intensive.

Regarding the landlord's concern about "what should I do if the Volkswagen Bora engine failure light is on", the following is my personal opinion:

What should I do if the Volkswagen Bora engine fault light is on? The Volkswagen Bora engine fault light is on, and the treatment method is as follows:

1. The first is that the car cannot be started, which may be caused by the failure of the fuel pump or ignition parts, and you need to call ** directly for help;

2. The second is that the fault light is on, but there is no abnormality in driving, which may only be a sensor failure, and you need to slow down to a nearby maintenance shop at low and medium speed;

3. The third is that the fault light is on, and the vehicle can be driven, but there are symptoms such as severe shaking and acceleration weakness, and you need to wait for rescue.

Bora ( Check price |.)The engine fault light is always on should be a problem with the engine sensor, caused by the abnormal data of the monitored combustible mixing ratio, and it can be detected and replaced by a computer in the repair shop.

There are many reasons why an oxygen sensor can fail, such as not changing the oil regularly or not cleaning the engine from the coolant in a timely manner. If the oxygen sensor fails, fuel consumption may increase by more than 40% compared to usual. When there is an abnormality in the thermostat, the engine fault light will also turn on.

If you see that the water temperature gauge has not been able to rise to the ideal temperature (generally 90 degrees) in the car for a long time, the fault light will turn on when you start the messy manuscript stop. In general, the coolant is not replaced within the specified number of kilometers or the engine water tank does not have a heat dissipation function, resulting in engine overheating, which will cause rust or even damage to the thermostat.

The fault light of the engine is generally due to the failure of the engine's electronic control system, sensors, and wiring, and then the fault light is on. Go to 4S and use a special computer diagnostic instrument to read the fault**, you will probably know that it is the problem**, and then check and repair it according to the fault**.
