* Buick's engine fault light is DigiPlus fair valueon, which is a very annoying thing for the owner. The engine fault light is flashing, which means that the vehicle has a fault or problem and needs to be dealt with in time, otherwise it may cause greater damage to the vehicle. In this article, we will introduce the reasons, handling methods and preventive measures for Buick owners to turn on the engine fault light. I. The reason why the engine fault light is on 1. Engine electronic control system failure The engine electronic control system is the core part of the on-board electronic control unit. If a failure occurs, it is easy to cause the engine failure light to light up. In this case, the operation performance of the vehicle may be affected, such as difficulty in starting, slowing down, etc.Two. Engine mechanical failure If the mechanical failure causes the fault light to turn on, it may be caused by tire imbalance, ignition system failure, excessive fuel consumption and other reasons. Mechanical failure will not only affect the vehicle, but also may endanger driving safety. Therefore, once the fault light is found, it should be checked and repaired in time. 3. If the temperature is too high, if the temperature of the engine is too high, it will also cause the fault light to turn on. At this time, you can slow down on the highway, open the window for ventilation and heat dissipation at the same time, and carry out overhaul after cooling down to avoid aggravated damage. II. Handling method 1. Parking check If the engine fault light is on, you should park in a safe place and determine whether there are any obvious mechanical faults through the exterior inspection. If not, you can try to restart the vehicle. If there is still a problem, you should find professional technicians with relevant repair capabilities.Two. Check the engine oil level. Low engine oil may cause the fault light to turn on, so it is necessary to check and add engine oil. When adding oil, the correct model and grade of oil should be added according to the manufacturer's requirements, otherwise it may lead to slow acceleration and aging of the engine. 3. If abnormality is found in regular maintenance, parts should be replaced in time to avoid more serious mechanical failures. If necessary, you should seek the help of experienced technicians. III. Precautions 1. Regular maintenance inspection Regular engine maintenance inspection can effectively prevent or find potential faults. For the shiny engine fault light, we should first enter the interior of the car for inspection, and at the same time understand the position of the front wheels, maintenance, road conditions and other factors of the car. If there is a problem, it should be repaired as soon as possible.Two. Slow start, refueling, stable driving. Car owners should be familiar with the performance and ability of the car. When there are rough or special roads, they should avoid excessive bumps, control the driving speed, slow start, no overload, no excessive acceleration and sudden braking to ensure the high stability of the car. 3. Quick troubleshooting. Once the engine fault light is found to be on, it should be handled quickly to avoid more serious mechanical failures. If you encounter car repair problems, you should choose a car repairperson with handling skills. Don't forget to contact the Buick dealer or the official to track the after-sales service.
