What are the reasons for the engine warning light in the Lynk & Co 02?

[LaEvan]

The engine warning light in the Lynk & Co 02 may illuminate due to the following 7 main reasons: Sensor malfunction: The sensors mentioned here include those for coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which may trigger the engine warning light. Fuel or oil quality issues: If fuel or engine oil is not added as required by the manufacturer, it may cause engine wear and lead to the illumination of the warning light. Poor combustion of the air-fuel mixture: Poor combustion can result in engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines can cause poor combustion of the air-fuel mixture. Turbocharging problems: Issues with the intake turbocharging pipeline or turbocharger can also cause the engine warning light to illuminate. The most common issue is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If there is an issue with the vehicle's intake, it may lead to clogged engine pipelines, and in severe cases, trigger the engine warning light. A dirty or uncleaned air filter can cause intake problems. Exhaust problems: Exhaust system faults can also cause the engine warning light to illuminate. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearing wear. The catalytic converter is the most frequent culprit. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily lead to catalytic converter failure. 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 prevent the engine from operating normally and trigger the engine warning light. If the engine warning light illuminates, follow these steps: First, check whether the engine is running normally, such as if there is shaking, black smoke, etc. If such symptoms are present, avoid restarting the engine. Particularly, 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. Without pressing the brake pedal, press the start button once or turn the key halfway to the 'ON' position without pressing the clutch. The vehicle will perform a self-check after powering on. Wait for 5-10 seconds and observe whether the warning light on the dashboard turns off. If the warning light remains on, visit a service center as soon as possible to diagnose the issue. The service center can use a portable diagnostic tool to read the fault codes, identify the problem, and perform targeted repairs.

I just encountered a situation where my friend's check engine light came on, which usually indicates a minor issue with the engine. The most common causes are problems with the exhaust system's sensors or unburned fuel clogging the catalytic converter. Sometimes, it's just old ignition coils or spark plugs causing rough starts. Don't panic—first, check if the fuel cap is tightened properly, as even small things like that can trigger the engine warning light. If the light stays on, quickly visit an auto repair shop to use an OBD diagnostic tool to read the trouble codes, which can pinpoint the exact issue. Delaying repairs might worsen the situation, leading to increased fuel consumption or even engine damage. Regular maintenance, such as checking the air filter and changing the oil, can prevent these problems. A car is like a person—it needs careful attention. Safety comes first, especially when driving a performance car like the Lynk & Co 02 in the city. Address any issues promptly.
