355 and 380 brake discs differ by 25mm in diameter. The former has a diameter of 355mm, while the latter has a diameter of 380mm. The function and advantages of brake discs: Simply put, a brake disc is a round disc. The brake caliper clamps the brake disc to generate braking force. When the brake is applied, the brake disc clamps to slow down or stop the vehicle. Brake discs offer excellent braking performance and are easier to maintain compared to drum brakes. Classification of brake discs: Disc brake rotors are divided into solid discs (single-piece discs) and ventilated discs (two-piece discs). Solid discs are straightforward—they are solid. Ventilated discs, as the name suggests, have ventilation properties. Externally, ventilated discs have numerous holes around the circumference leading to the center, known as ventilation channels.

What Causes the Engine Warning Light to Illuminate in a Range Rover Evoque?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: The sensors referred to here include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen, etc. When these sensors are damaged, have poor contact, or their signals are interrupted, 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, leading to the illumination of the warning light. Poor combustion of the 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 an alert. Spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline or turbocharger can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leakage, high oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. 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 system faults can also cause the engine warning light to illuminate. Common causes include rear oxygen sensor failure, three-way catalytic converter failure, exhaust camshaft and bearing failure, with the three-way catalytic converter being the most frequent issue. The use of leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel supply system faults can easily lead to three-way 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 is on, follow these steps: First, check whether the engine is running normally, and if there are issues such as shaking or black smoke, 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 pressing the clutch. The vehicle will perform a self-check after powering on. Wait for 5-10 seconds to see if the warning light turns off. If the warning light remains on, visit a service station as soon as possible for diagnosis. The service station can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.
