BMW's second maintenance requires replacing the engine oil, oil filter, air filter, fuel filter, and cabin air filter. The second maintenance also involves checking the engine's working condition, such as whether the pipeline connections are normal, if there are any leakage points, and if the engine sounds normal. Additionally, the vehicle will be lifted to inspect the chassis components for scratches or corrosion, as well as checking the braking system, suspension system, and the inner side of the tires. Related introduction to car maintenance: Content: Modern car maintenance mainly includes the maintenance of the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. Purpose: The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent failures, slow down the deterioration process, and extend the service life.

The second maintenance for a BMW is typically performed between 10,000 to 15,000 kilometers, depending on the mileage. I recommend focusing on changing the engine oil and oil filter, as BMW engines are quite precise, and fresh oil can reduce wear and keep the engine running smoothly. The air filter should also be replaced to prevent dust from clogging the intake and affecting power output. Other routine checks include the braking system—inspecting brake pad thickness and fluid levels to avoid failure in emergencies—and tire pressure and alignment checks to ensure driving stability and fuel efficiency. Testing the lights and wipers is also essential to maintain clear visibility at night or during rain. It’s best to schedule an appointment in advance at an authorized BMW service center and bring the maintenance manual; the entire process usually takes about one to two hours if everything goes smoothly. Sticking to regular maintenance helps the car last longer and stay safer, offering great value—spending a little now to prevent major repairs later is definitely worth it.

What to Do When the Steering Wheel Locks?

The solution to a locked steering wheel is: insert the steering wheel key, then gently wiggle the steering wheel left and right to unlock it. Typically, steering wheels can be categorized into power-assisted and non-power-assisted types. The former requires 1.5 turns to fully lock the steering wheel, while the latter, found in older models, requires 2 turns. Steering wheel lock is a very basic anti-theft feature of a car. Its principle involves using the rotation of the key to control a steel pin via a spring. When the key is removed, any movement of the steering wheel causes the steel pin to pop into a pre-drilled hole, thereby locking the steering wheel to prevent rotation. When the steering wheel is locked, it cannot be turned, the key cannot be twisted, and the car cannot be started, thus achieving anti-theft.

What Does Idle Speed Mean?

Idle speed refers to an operating condition of a car where the engine runs in neutral gear. The engine speed during idle is called the idle speed, which can be adjusted by modifying the throttle opening size, among other methods. Idle speed means the engine is "producing power without doing work." When the engine is running, if the accelerator pedal is fully released, the engine enters idle mode. When adjusting the idle speed, the RPM should not fluctuate abruptly, as this can cause premature wear to the engine. It is best to have the idle speed adjusted at an automotive repair facility. The idle speed can be adjusted by modifying the throttle opening size or the idle fuel supply. Generally, the optimal idle speed is the lowest RPM at which the engine operates smoothly within the idle range and maintains good acceleration performance.

What is the normal tire pressure for cars?

Standard tire pressure is 2.4-2.5 bar, reinforced tire pressure is 2.8-2.9 bar, and the maximum tire pressure should not exceed 3.5 bar. If the tire pressure is too high or too low, it needs to be addressed promptly to avoid affecting the normal operation of the vehicle. Factors affecting tire pressure: The tire pressure standard also depends on the type of tire and the vehicle model. Different vehicle models have varying weights, heights, and tire sizes, requiring different tire pressures. Standard tire pressure is 240-250 kPa, while reinforced tire pressure is 280-290 kPa. Additionally, cold tires and hot tires have different pressures, with hot tires having about 20 kPa higher pressure than cold tires. Moreover, tire pressure is significantly influenced by seasonal factors. In summer, high temperatures can cause tires to heat up during driving, and high pressure can lead to blowouts, so the pressure should be slightly lower. In winter, tire pressure should be slightly higher than in summer due to thermal contraction and expansion. Generally, a tire pressure of 250-280 kPa is suitable for cars in winter. Precautions for checking tire pressure: Observe the tire condition before traveling. Radial tires—commonly known as low-pressure tires—should have sufficient flexibility when pressed with the foot, not feeling too soft. High-pressure tires—bias-ply tires with inner tubes—should not have bulging shoulders when viewed from the front, and the contact area with the ground should be normal when viewed from the side. While driving, pay attention to the sound of tire friction with the ground, the cushioning effect on smooth roads, and any changes in acceleration compared to normal conditions. These observations help build experience. Normally, check and adjust the tire pressure at a professional tire repair shop every week.

How to Turn on Fog Lights?

To turn on the fog lights: 1. Activate the vehicle's parking lights, locate the fog light symbol on the light control lever, and rotate the control ring to align the front fog light symbol with the activation point. The dashboard will then display that the front fog lights are on. 2. Rotate the control ring to align the rear fog light symbol with the activation point, and the dashboard will show that the rear fog lights are on. Front fog lights are designed to enhance illumination in unclear road conditions, providing a high-intensity scattered light source that penetrates thick fog and alerts oncoming drivers. Rear fog lights are installed at the rear of the vehicle to ensure visibility for other road users in low-visibility conditions such as fog, snow, or rain, emitting a stronger light than the tail lights.

What does 'sport' mean on a car?

The 'sport' mode on a car refers to the vehicle's sport mode. In this mode, the electronic control unit (ECU) increases the engine's RPM to maintain sufficient torque, enhancing power performance, but at the cost of higher fuel consumption. This mode temporarily boosts engine power for quick acceleration, essentially acting as an acceleration gear, hill-climbing gear, or overtaking gear. Engaging sport mode causes a sharp increase in RPM. Additionally, high RPM in sport mode can help clean engine carbon deposits, but it should not be used continuously. In sport mode, the transmission experiences increased load, higher temperatures, and accelerated wear. Sport mode is suitable for complex real-time road conditions such as highways, muddy roads, or new roads, or when the vehicle needs to carry heavy loads. Furthermore, in some higher-end cars, switching to sport mode makes the suspension damping stiffer, thereby improving the vehicle's overall performance. Modern automatic transmissions are designed to meet different driving requirements and adapt to various road conditions. The ECU includes different shift logics, and the control panel features a mode selection switch, allowing drivers to choose the transmission control mode. Common automatic transmission control modes include: Standard Driving Mode (Normal): This is the most commonly used mode. In this mode, the car's performance is balanced in terms of fuel efficiency, quietness, and power, making it ideal for urban driving. Power Mode (Power): This mode is designed to maximize the car's power performance. The shift logic ensures the engine operates within high-power ranges, improving acceleration and hill-climbing ability. Snow Mode (Snow): Some automatic cars have a 'snowflake' button near the gear lever, which activates snow mode. This mode programs the transmission to start in second gear, ensuring smoother and gentler torque output to reduce wheel spin on slippery snow. Individual Mode (Individual): This mode allows customization of various modules, such as steering weight, chassis stiffness, throttle response, transmission reaction, engine mode, steering system mode, and exhaust system mode. Eco Mode (Eco): In this mode, the ECU analyzes factors like transmission gear, engine RPM, speed, braking, and transmission oil temperature to calculate the optimal fuel supply, effectively reducing fuel consumption compared to normal driving mode.
