Why does the engine warning light come on in my newly purchased 2021 Excelle?

There are mainly 7 reasons why the engine warning light comes on in an Excelle: Sensor malfunction: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption occurs, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine warning light. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of air-fuel mixture: Poor combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, and fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: Intake turbocharging pipelines and turbochargers can also cause the engine warning light to come on. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, and blue or black smoke from the exhaust pipe. Intake issues: If there is a problem with the vehicle's intake, it may lead to engine pipeline blockage, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust faults can also trigger the engine warning light. Rear oxygen sensor, three-way catalytic converter, exhaust camshaft, and bearing failures are all causes of exhaust problems, with the three-way catalytic converter being the most common. Using leaded gasoline, lead or silicon-containing lubricant additives, physical damage to the three-way catalytic converter, or fuel system failures can easily cause three-way catalytic converter issues. Anti-theft system malfunction: If the vehicle's electronic anti-theft system malfunctions, or if the anti-theft controller does not match the engine electronic controller, the anti-theft system can also prevent the engine from operating normally and trigger the engine warning light. If the engine warning light comes on, follow these steps: First, check if the engine is running normally and if there are issues such as shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off for 5-10 minutes, then without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The vehicle will enter self-check mode after powering on. Wait for 5-10 seconds and observe if the warning light on the dashboard turns off. If the warning light remains on, visit a service station as soon as possible to diagnose the issue. The service station can use a portable diagnostic tool to read the fault code, obtain fault information, and perform targeted repairs.

How to Check Coolant Level?

Here are the methods to check coolant level: 1. Check the MIN (minimum) and MAX (maximum) markings on the car radiator. The coolant level should be maintained between MAX and MIN for normal operation. 2. If the coolant level is below MIN, it indicates insufficient coolant and requires immediate replenishment. Below is relevant information about coolant: The primary function of coolant is to cool the engine, with additional anti-rust properties. It mainly consists of compounds like water, ethylene glycol, and propylene glycol, with specified boiling and freezing points. Particularly important is coolant's freezing point, typically around minus forty degrees Celsius.

Does the BMW X3 rearview mirror have a water droplet removal function?

The BMW X3 rearview mirror can use the heating function to remove water droplets. Automatic heating: The BMW X3 rearview mirror heating switch is integrated with the rear window defogger switch. When the rear window defogger is activated and there is a temperature difference of 6 degrees between the inside and outside of the vehicle, the BMW will automatically heat the mirrors to remove water droplets. Using the rear windshield heating function: When the rear windshield is heated, the rearview mirrors are also heated. Using the automatic wiper sensing heating function: When the green light above is on, the exterior mirror heating automatically starts.

What does vehicle damage assessment mean?

Vehicle damage assessment refers to the process where insurance company assessors determine the damaged parts of a vehicle by visiting the accident site and taking photos. They then decide which parts need to be replaced or repaired, and finally determine the loss amount. Essentially, it's the confirmation of the financial loss caused by the accident, which only becomes valid when both parties involved in the accident agree. Below is relevant information: The principle of vehicle damage assessment is based on automotive construction theory. Through scientific, systematic professional inspection, testing, and surveying methods, it conducts comprehensive analysis of vehicle collisions and accident scenes. Utilizing vehicle damage assessment data and repair records, it provides a scientific and systematic pricing for collision repair costs.

What is the normal voltage of an oxygen sensor?

The normal voltage of an oxygen sensor ranges between 0.1 and 0.9V. Here are the specific details about oxygen sensors: 1. The oxygen sensor is a standard configuration in automobiles, utilizing the Nernst principle; 2. It measures the oxygen potential in the exhaust pipe of a vehicle using a ceramic sensitive element, calculates the corresponding oxygen concentration based on chemical equilibrium principles, and serves as a measuring component to monitor and control the air-fuel ratio of combustion to ensure product quality and compliance with exhaust emission standards; 3. It features advantages such as simple structure, rapid response, easy maintenance, convenient use, and accurate measurement.
